Zion National Park is situated in South Utah in United States. Zion National Park covers an extensive area of 146,578 acres. Zion National Park is an unique biosphere located at the junction of the Colorado Plateau, Great Basin and Mojave Desert. It is famous for various landscapes with unique life zones. The main attraction of the park is the Zion canyon, a slit of 24 kilometers in length and up to 800 meters deep excavated by the north arm of the Virgin River on red sandstone terrain. Other points of interest are the Great White Throne, the narrows of the Virgin River and the Kolob Arch. In the area of ​​the Zion and Kolob canyons, there are nine geological formations that date back 150 million years, originating from sediments that occurred during the Mesozoic Era, time of the dinosaurus. During all that time, the region has been covered by swamps, streams, ponds, lakes, vast deserts and dry beds. The elevations caused by the Colorado plate raised the region some 3,000 m 13 million years ago.

The first humans arrived in the area 8000 years ago. They were small family groups of Amerindians who settled in the region such as the weavers of Anasazi baskets that arrived in 300 AD. The increasingly nomadic habits prompted this people to move to what is now known as Virgin Anasazi in the 500 AD. Another group, the Parowan Fremont also inhabited the area. Around the fourteenth century there was the mysterious disappearance of both groups, arriving in the area the Parrusits ​​and other southern tribes. The cannon was discovered by the Mormons in 1850, inhabiting it two years later. In 1909, the Mukuntuweap National Monument was created, intended for the protection of the canyon. In 1919 it was decided to extend the protection thus creating the Zion National Park. Zion or Sion means in ancient Hebrew place of refuge or sanctuary as a reference to mount Sion in Jerusalem. The Kolob section was proclaimed Zion National Monument in 1937 but became a park in 1956.

Zion National Park is located at the junction of the Colorado plate, the Great Basin and the Mojave Desert. The unique geography and the variety of ecosystems allow the existence of an important diversity of flora and fauna. There are 289 species of birds, 75 of mammals (including 19 species of bats), 32 species of reptiles as well as a large number of plants. Biodiversity is distributed through four zones: desert, riverbanks, forests and coniferous forests. Among the fauna highlights the puma, deer, eagles, California and mountain goats.

 

Fees and permits

A $30 entrance fee is required for all private vehicles entering the park that is good for seven days. Motorcycles, individuals on foot, and bicyclists are charged a $12 entrance fee. Private vehicles which only visit Kolob Canyons still need to pay the $30 entrance fee (good for the whole park).

There are several passes for groups traveling together in a private vehicle or individuals on foot or on bike. These passes provide free entry at national parks and national wildlife refuges, and also cover standard amenity fees at national forests and grasslands, and at lands managed by the Bureau of Land Management and Bureau of Reclamation. These passes are valid at all national parks including Zion National Park:

The $80 Annual Pass (valid for twelve months from date of issue) can be purchased by anyone. Military personnel can obtain a free annual pass in person at a federal recreation site by showing a Common Access Card (CAC) or Military ID.
U.S. citizens or permanent residents age 62 or over can obtain a Senior Pass (valid for the life of the holder) in person at a federal recreation site for $80, or through the mail for $90; applicants must provide documentation of citizenship and age. This pass also provides a fifty percent discount on some park amenities. Seniors can also obtain a $20 annual pass.
U.S. citizens or permanent residents with permanent disabilities can obtain an Access Pass (valid for the life of the holder) in person at a federal recreation site at no charge, or through the mail for $10; applicants must provide documentation of citizenship and permanent disability. This pass also provides a fifty percent discount on some park amenities.
Individuals who have volunteered 250 or more hours with federal agencies that participate in the Interagency Pass Program can receive a free Volunteer Pass.
4th graders can receive an Annual 4th Grade Pass that allows free entry for the duration of the 4th grade school year (September-August) to the bearer and any accompanying passengers in a private non-commercial vehicle. Registration at the Every Kid in a Park website is required.
In 2018 the National Park Service will offer four days on which entry is free for all national parks: January 15 (Martin Luther King Jr. Day), April 21 (1st Day of NPS Week), September 22 (National Public Lands Day), and November 11 (Veterans Day weekend).

 

Geography

The national park is located in southwestern Utah in Washington, Iron and Kane counties. Geomorphologically, the park consists of the Markagunt Plateau and the Kolob Plateau at the intersection of the Colorado Plateau, the Great Basin, and the Mojave Desert. The northern portion of the park is referred to as Kolob Canyons and is accessible from Interstate 15 via exit 40. To the south runs Utah State Route 9, which at Mt. Carmel Junction joins the U.S. Hwy 89 joins. Many topographical names were taken from the Bible by the Mormon settlers. The List of Peaks in Zion National Park lists some of the significant peaks.

Rivers in the park follow perpendicular clefts in the rock. The Virgin River begins at the confluence of the East Fork and North Fork at 3,500 feet (1,147 m) and empties 200 miles (320 km) southeast into the Colorado River, now in Lake Mead Reservoir, at an elevation of 1,200 feet (367 m). meters. This makes it the river with the highest gradient in North America.

 

History

early history
Finds show that since 6000 BC. BC people settled in this area to collect plants and seeds and to hunt animals. Around the birth of Christ the first corn plantations came into being. Remains of pueblos indicate a settlement up to the year 500 AD. Some finds of baskets, ropes and sandals made from yucca palm fibers date from this period. Knife blades and arrowheads were also found. However, the arrows were not used with a bow, but with a throwing device called an atlatl. Some groups settled in the area of today's park and developed into the Anasazi, also known as basket makers. This happened around 300 AD. They stored food and sometimes built underground dwellings, but they were still hunter-gatherers who expanded the food supply through agriculture.

Early Indian settlement
The Anasazi were so dependent on agriculture from around AD 500 that they built pueblo-like settlements along the Virgin River. However, these only accommodated small groups and never grew into Pueblo towns, as is known from Mesa Verde National Park. The plants were located on terraces slightly above the river, from which one had a view of the fields on the banks of the river. The sedentary groups in this period are called Virgin Anasazi by archaeologists. They left numerous petroglyphs.

At the same time, the Fremont People emerged to the north of the park. The finds from that period show characteristic differences from those of the Anasazi. Only in the area of the Kolob Canyon one finds finds of both cultures mixed. It is believed that the two peoples traded with each other here, but otherwise lived separately.

In both cultures, maize and squash were mainly grown. Ceramic objects used for storage were found. Both the Anasazi and Fremont People left the area for unknown reasons around 1300. Major droughts followed by brief but severe floods may have been a cause. The intrusion of Ute and Paiute around 1100 and thus a competitive struggle would also be a possible reason for the disappearance.

Later Indian settlement
The Paiute Indians advanced to the Virgin River. In contrast to the displaced Anasazi, however, they migrated back and forth along the Virgin River seasonally, since they obtained their sustenance mainly by gathering seeds and nuts and engaged in agriculture and hunting only as a supplement. The Paiute had strong religious ties particularly to the cliffs, rivers, and springs in Zion Canyon and believed they were responsible for that area. Even today, Paiute Indians come to the park for religious reasons, but also to collect rare plants.

Discovery and exploration by whites
In the late 18th century, Utah was explored by white people for settlement. The first historically documented exploration was undertaken by two Spanish Franciscan Fathers, Francisco Antanasio Domínguez and Silvestre Vélez de Escalante, in 1776. In 1826, trapper and fur trader Jedediah Smith led an expedition to the area with the aim of finding a route to California. Other expeditions from the New Mexico direction paved the Old Spanish Trail, which was largely based on the Virgen River. The officer John C. Frémont wrote down his impressions of the area in 1844, whereupon further trails were established.

First settlement by whites
Around 1850, Mormon farmers and cotton planters from Salt Lake City first entered and began to settle in the region around the Virgin River. Cedar City was founded in 1851, and the area of present-day Kolob Canyon served as a natural resource for timber, but also as a grazing ground for cows, sheep, and horses. Some rivers were diverted for mineral prospecting, but the productivity of the mines was very small. Mormons gave the area the name Kolob - for the Mormons the star closest to the abode of God.

In 1858, the settlers advanced as far as Zion Canyon, 120 kilometers away, which had not been discovered by whites until then. Paiute Indians led Nephi Johnson into Zion Canyon. Johnson Mountain was later named after him. Johnson was impressed by the sparse Indian planting and wrote a report praising the canyon's agricultural potential. In 1861, Joseph Black built the first farm in the canyon, but it wasn't until Springdale was founded in 1862 that the canyon caught the attention of farmers. Farmers settled in the canyon until 1863, including Isaac Behunin, who gave the canyon its current name. Mainly sugar cane and tobacco were planted, but also fruit. However, a high tide and limited cultivation opportunities in the canyon reduced yields, and interest in the canyon for agricultural use quickly waned. The Paiute Indians lived in the canyon until they were settled, but were already severely decimated by diseases and slavery that were previously unknown to them. Intensive farming by the immigrants quickly shrunk their living space, and eventually they emigrated altogether. They did not resettle the canyon either, when many farmers left the area a short time later until 1909, when no one worked the land anymore.

In 1869, John Wesley Powell explored the entire region coming from the direction of the Grand Canyon. Along with geologist Grove Karl Gilbert, he mapped Zion Canyon and named it Mukuntuweap, thinking it was the Paiute term for the canyon.

emergence of the park
A flood of published expedition reports, drawings and photographs and not least a newspaper report in Scribner's Magazine led to the then President William Howard Taft declaring the region around Zion Canyon Mukuntuweap National Monument on July 31, 1909. In 1918, the National Park Service renamed the national monument Zion National Park. On November 19, 1919, the park was enlarged and given national park status. In 1937 the Kolob Canyons were added, and in 1956 another expansion took place in the Kolob Canyons area.

Tourism was initially very sparse due to a lack of infrastructure. Only the disused portion of the Old Spanish Trail from Springdale along the Virgin River entered the park. In 1896, Zion Ponderosa Ranch farmer John Winder expanded a disused trail within the Long Valley, which the park officials continued to expand and now known as the East Rim Trail.

The Utah State Road Commission, founded in the year of the proclamation as a national monument, planned a road in the south of the park in the year of its founding, today's Highway 9 (Zion-Mount Carmel Highway). The first paved road from Cedar City to Springdale was completed in 1913. The Union Pacific Railroad began building a railroad line. After the completion of a road to Wylie Camp, cars could drive right into Zion Canyon, and the Utah Parks Company, a division of the Union Pacific Railroad, offered combined ten-day train and bus trips to Zion Canyon and Bryce Canyon National Park.

From 1920 to 1927, the Zion Canyon Lodge hotel, designed by architect Gilbert Stanley Underwood, was built near Wylie Camp. Construction was financed by the Utah Parks Company. The hotel burned down a short time later, but was rebuilt immediately afterwards. Only the log cabins belonging to the hotel did not fall victim to the flames. They are now listed on the National Register of Historic Places.

The Zion–Mount Carmel Highway (Utah State Route 9) was built from 1927 to 1930. He also opened up the Zion Canyon from the east with engineering structures that had not previously been thought possible. This also enabled a direct connection to nearby Bryce Canyon National Park and thus a round trip between them and the northern rim of Grand Canyon National Park. The highway is 40 km long and contains a nearly 2 km long tunnel. It is listed on the National Register of Historic Places and has been designated a Historic Civil Engineering Landmark since 2012.

 

Geology

The nine visible rock layers in the park are part of a very large rock formation called The Grand Staircase. It stretches from Bryce Canyon to the Grand Canyon. The layers, whose sedimentation sequence from bottom to top can be read largely undisturbed, go through 300 million years of geological history, with most of the deposits taking place in the Mesozoic. The oldest layers are intersected in the Grand Canyon, the uppermost layers of the Grand Canyon are identical to the deepest ones in Zion Canyon. Its uppermost and thus youngest rock layer continues in the lowest and therefore oldest layer in Bryce Canyon, which is the youngest of the three canyons. Four different climatic situations were the prerequisites for the formation of the various formations:

a shallow, warm sea, often retreating, formed the Kaibab and Moenkopi Strata
the Chinle, Moenave and Kayenta layers formed in streams, ponds and lakes
the Navajo and Temple Cap strata formed in extensive deserts
dry coastal landscapes gave rise to the Carmel and Dakota layers

About thirteen million years ago, the uplift that led to the formation of the Colorado Plateau began. The layers were last more than 3000 meters above their level of origin. This gave the forerunners of the Virgin River and other rivers an enormous gradient and high flow rates with a correspondingly strong erosion effect. Cracks and chasms formed during uplift became steep gorges by river erosion in the Cenozoic. Zion Canyon was formed this way by the Virgin River, which eroded up to 3 million tons of rock a year. The tributaries that formed later had much less erosion, so waterfalls and hanging gardens often formed. Most of the falls are temporary, flowing for a few days after thunderstorms, slightly longer during snowmelt. The most famous are those of Emerald Pool, whose jet plummets far from the overhanging wall, and the Temple of Sinawava Waterfall, accessible only by a longer trail. One of the tallest falls, clearly visible from the Zion-Mount-Carmel Highway, tumbles over the west wall of the canyon between Sentinel Peak and Streaked Wall.

Dakota Formation
The Dakota Layer is the youngest layer of sediment visible in the park and was formed in the Cretaceous Period. The sandstone interspersed with basaltic material is only found at the top of the Horse Ranch Mountains. The layer is rich in fossils and is quickly eroded by wind and weather.

Carmel Formation
A warm and shallow sea formed 150 million years ago, eroding countless sand dunes. Calcareous mud sedimented together with the sand to form a 30 to 120 cm thick layer of rock, in which fossils from the Triassic can be found. Small amounts of the calcareous mud penetrated under the sand layer of the eroded dunes and mixed there with the Navajo layer. The remaining layer of mud petrified and, together with the sand sediments, forms today's Carmel layer, which is 60 to 90 meters thick. This layer is visible only in the Kolob Canyons and near the Mount Carmel crossing. In the sequence of layers, after the Carmel layer, there are indications of another layer, probably up to 850 meters thick, which was completely removed by erosion.

Temple Cap Formation
In the early Jurassic period, streams of water with a high iron oxide content flooded the area, the sedimented iron oxide mud forms today's Temple Cap layer. Layers of silt and clay indicate the end of this sedimentation, when the area briefly changed to become desert-like. The Temple Cap Layer is best viewed at the East Temple and West Temple in Zion Canyon. Iron oxide washed out by rain forms characteristic red streaks, which are particularly evident at the Altar of Scrifice. Penetrated iron oxide also stains the lower part of the Navajo layer orange to red.

Navajo Formation
The Navajo Layer is the most significant and largest formation. It stretches from Wyoming to southwest California. Wherever it is subject to erosion, water erosion rapidly forms canyons. In Zion Canyon at the Temple of Sinawa, this layer has its greatest thickness of over 700 meters and is considered the world's thickest sedimentary layer. The Virgin River has cut down to the Kayenta Layer. The sandstone is extremely porous and can absorb large amounts of water, which seeps into the stone. It emerges at the boundary with the impermeable Kayenta layer, the so-called source line. The springs are the cause of the many hanging gardens in the park and still today form cliffs, arches and overhangs by leaching out the binding components of the sandstone.

Kayenta Formation
The 60 to 180 meter thick Kayenta Layer was formed from Early Jurassic sand and silt by slow flowing waters in a semi-arid to tropical environment. In this layer, footprints of some dinosaurs were found near the Left Fork of North Creek. The Kayenta Layer is red to purple in color and is composed of sandstone, siltstone and shale. It can be seen almost anywhere in the park.

Moenave Formation
At the beginning of the Jurassic period, the Moenave layer was uncovered by uplift of the area. It consists mainly of reddish siltstone interspersed with clay and sandstone. This 40 to 120 meter thick layer was formed by rivers, ponds and larger lakes, which is why many fish fossils can be found.
Above this red layer there is another brown layer, which is also counted towards the Moenave formation. It is 20 to 50 meters thick and consists mainly of sandstone. It was mainly deposited from larger rivers with plenty of water, which is evident from the fossils found, mainly of freshwater fish, e.g. B. the sturgeon can be read.

Chinle Formation
The mineral-rich chinle layer, heavily interspersed with volcanic ash, contains petrified wood and amphibian fossils, suggesting formation in a swampy environment. The color spectrum of this layer, caused by various embedded minerals, ranges from violet, pink, blue, white, yellow to red. The basic substance consists of slate, gypsum, limestone and quartz. The most common minerals are iron, manganese and copper compounds.
The silicic acid that contributes to the fossilization probably came from volcanic ash, but silicic acid dissolved in the groundwater is also responsible for the fossilization. It is the same layer that formed and preserved the fossils found in the Petrified Forest National Park.

Moenkopi Formation
In the early Triassic, sediments formed in a shallow lagoon composed of gypsum, clay, sandstone, limestone and shale deposited in thousands of very thin layers. Overall, the Moenkopi layer is up to 550 meters thick. The shoreline of the lagoon must have receded several times during sedimentation, as characteristic mud deposits of an estuary can be seen.

Kaibab formation
In the Permian, on the site of today's park, there was a warm ocean. Yellowish-grey limestone sedimented over 260 million years ago as fossil-rich mud. The fossils found indicate a tropical climate that prevailed at the time. Sponges proliferated during this time. Siliceous minerals contained in their bodies formed silica and flint in this layer under the high pressure. The Kaibab Layer can only be seen in the park at the Hurricane Cliffs above the Kolob Canyon Visitor Center.

 

Ecosystems

Zion National Park is divided into three natural areas according to its terrain. The rock plateau is more than 2000 meters high in the subalpine zone, the canyons cut deep into the plateaus, in them foothills of the Mojave Desert extend into the park. These two natural areas are separated by steep rock faces and small side canyons, which have completely different climatic conditions depending on their orientation.

 

Fauna

The cottontail rabbits can be seen all over the park. The diverse bird world includes the American dipper, which does not have a white throat, as well as the American falcon and recently (again) the condor. Finches, including the evening hawfinch, can be seen in all areas of the park. Although rarely seen, there are significant numbers of cougars, primarily in the Kolob and Parunuweap Canyon areas. Cougars are the natural enemies of the mule deer, which can also be found in the park. Other hunters include the gray fox and the cat frette. Normally they inhabit the same habitat, have the same prey and crowd each other out. In the park, however, both species coexist. While the gray fox hunts more on the ground, the cat frette specializes in climbing. The bobcat can be seen in rocky and steep places. A few beavers have settled along the Virgin River. Many rodents populate the park, which serve as prey for the coyotes. Several species of squirrels also live in the park.

 

Vegetation

valley bottoms of the canyons
The floors of the main canyons enter the park from the southeast. They are associated with the transition zone between the Mojave Desert and the Great Basin Desert. Typical animal and plant species of these two desert regions live in them. Agaves, cacti and various Helianthus species are common. There are also mugworts, opuntias, thorn apples and several broomrape plants.

The soil of the great canyons is completely different, where the park's rivers and streams provide adequate moisture and nutrients. Riparian forests of ash maple, cottonwood poplar, willow, and ash grow in the Virgin River valley in the main part of Zion National Park and Taylor Creek in Kolob Canyon.

Rock walls and side canyons
The slopes of the canyons are divided into very small parts. Depending on the soil conditions and orientation to the sun, very different ecosystems are in the immediate vicinity. Few species can survive on the bare rock of the steepest walls and on the south-facing slopes. A few yuccas or a stunted juniper grow in one crevice or another, surviving the scorching sun. Pines and a few oaks can survive here.

As soon as the rock face in the narrow side canyons faces other directions, the picture changes: shade reduces temperatures and evaporation. If enough water is available, undemanding deciduous trees, oaks and some types of maple grow here, while Pinyon pine (Pinus cembroides) and Utah juniper (Juniperus osteosperma) grow in drier locations. The cliff rose (Purshia mexicana) is also native there. Common mahonia (Mahonia aquifolium) often grows on the ground. Ferns, mosses and wood sorrel grow where springs appear in the side canyons, occasionally in the form of "hanging gardens", where erosion has undermined and washed out rock walls and the plants grow over the rock edge in the form of tendrils and "beards" made of moss.

 

Plateau

The ecosystem on the rock plateau is shaped by its altitude. Conifer communities grow here with the yellow pine as the key species, mixed with Colorado fir, Douglas fir and American aspen.

 

Conservation and management

Zion National Park is controlled by the U.S. National Park Service administered and managed.

Invasive and native species
Over 100 species of plants have been introduced to the park since it was settled around 1850.

Native plants are grown in special greenhouses and released again. Rare plants are protected in the park with wire cages from deer browsing, but also from visitors.

birds of prey
After the peregrine falcon was no longer to be found, 15 pairs of the formerly native bird are now breeding again in the park. Pesticides found in the park probably damaged the eggs to such an extent that the falcon almost died out in this area. However, the canyons provide excellent hunting and breeding grounds. In order to enable the falcon to breed undisturbed, there are year-round or seasonal climbing bans on the rock faces.

In June 2014, the first breeding of a California condor was confirmed in the park and thus in the state of Utah. The parents come from a reintroduction project in the Arizona Strip, the local population spreads after successful breeding and Zion National Park is considered an excellently suitable habitat.

fire in the park
Fires are a necessary part of many ecosystems. Initially, the park administration viewed the bush and forest fires as destructive and fought them. This changed the ecosystem of the park, especially the pine forests, quite significantly. Since 1991, the fires that are most frequently caused by lightning have only been observed and, if necessary, contained. Sometimes the fires are set by the rangers to prevent large amounts of combustible material from accumulating, which can lead to major fires. Smaller fires are largely survived by healthy plants without damage. The new practice has confirmed that the fires are natural occurrences in the national park.

Virgin River
When the upper reaches of the river were designated as a National Wild and Scenic River in 2009, the national park had to adjust its management goals for the river. A report listing possible management alternatives was submitted in the summer of 2013, and in early 2014 the National Park Service decided to manage the Virgin River catchment area in the park primarily from the perspective of protecting natural resources and only allowing tourist use where it is needed Do not endanger nature conservation.

 

Climate

The climate in spring is changeable. Stormy, rainy days alternate with warm, sunny ones. The amount of precipitation reaches its maximum in March. Rainy days are usually clear and mild, nights can still get cold.

In summer, temperatures rise up to 43 °C, which cool down again to 21 °C overnight. Afternoon thunderstorms are not uncommon from mid-July to mid-September. These thunderstorms create short-lived waterfalls on steep slopes, and rivers can burst their banks with spring tides.

The discoloration of the foliage in autumn begins as early as September at higher altitudes and reaches its peak in mid-October.

Winters in Zion National Park are generally mild. Winter storms bring heavy rain and little snow into the canyon, with heavy snowfall at higher elevations. On clear days, the daytime temperature can rise to 16°C, and nights rarely drop below -7°C. The winter storms can last for several days. From November to March you should only drive through the park with winter-proof automobiles.

 

Tourism

Access to the national park is limited to three roads due to poor infrastructure in this part of Utah. Access from the east is only through the Zion–Mount Carmel Tunnel. Vehicles wider than 8 feet (2.38 m) or taller than 12 feet (3.45 m) must be escorted through the tunnel by rangers (for a fee of $15) as they cannot accommodate one lane due to their size. Vehicles over 3.98 m in height, over 12.19 m (40 ft.) in length or over 22.6 t (50,000 lbs.) are not permitted. Even taller vehicles can only access the park via the north entrance. The park is open year-round, but the Zion Canyon Scenic Drive is closed to public traffic from March to October. Only the (free) shuttles are allowed to travel this route, as well as the guests of the Hotel Zion Lodge in the canyon. Winter equipment is required in the months of November to March. There are no paved trails between Zion Canyon and Kolob Canyon to the north. Within the canyon, temperature and humidity can already reach extreme values in spring. You should therefore take enough drinks with you on every hike.

Hike
There are more than 150 miles of hiking trails within the park. Ranger-led hikes are offered at the visitor center, as well as lectures on geology and biology. A popular but also strenuous hike leads through Zion Canyon, the Narrows to Chamberlain Ranch. Guided tours on horseback are also offered.

Climb
Along with Yosemite National Park, Zion National Park is one of the most famous climbing areas in North America with hundreds of climbing routes. Unlike the granite of Yosemite Valley, the sandstone of Zion National Park is very sensitive. Climbing should not be attempted after it has rained because the soaked rock loses its stability and holds and steps can break off. This means that routes are damaged by climbers who do not follow the rules. The climbing equipment should also not hit the rock, even ropes rub off the rock.

Zion offers a wide variety of options, from short boulders to multi-day tours through big walls, walls up to 1200 meters high, but only in the higher and highest levels of difficulty up to 5.12. The best time for climbing is March to May and September to November. In midsummer, temperatures rise extremely, especially on the south faces, and the risk of thunderstorms is not low. A permit is required for routes that make a bivouac necessary or likely.

canyoning
Since the 1990s, canyoning (canyoneering in the USA), i.e. the descent through water-bearing gorges, has established itself as a popular extreme sport. The gorges of Zion Canyon are suitable for this and offer canyoning tours of varying difficulty. Guided canyoning tours can be booked through the visitor center and mountain guide offices in the national park. The risks, such as flash tides after thunderstorms, unpredictable currents and eddies and problems with abseiling should not be underestimated. The sport became known to a wider audience in the United States in 1993 when two leaders of a youth group died in an accident and the subsequent trial.

camping
There are three campgrounds in the park itself: South Campground and Watchman Campground with basic to medium facilities, and a very basic campground (Lava Point Campground) on Kolob Terrace Road. There is also a private campground with better facilities near Glendale, halfway to Bryce Canyon National Park. For multi-day hikes, which necessarily include camping, a permit from the park administration is required.

watching stars
Because of its remote location, Zion National Park is free from light pollution and is recognized by the Dark Sky Alliance. This makes it an ideal place to take a look at the starry night sky. Kolob Canyon and the eastern part of the park are better suited for this than Zion Canyon itself, because of its high cliff walls that limit the view upwards.

Sightseeing features
Angel's Landing
Angels Landing is a 1763m high rock formation accessed via a strenuous and partially exposed 8km trail over 450m of elevation gain. The path is extremely narrow in parts, but secured with chains, and offers spectacular views.

Emerald Pools
The Emerald Pools can be reached via the trail of the same name. This hiking trail, which runs through dense forests, is a popular day hike. The Emerald Pools are created by temporarily flowing rivers, the water from which seeps into the porous Navajo sandstone that can be found throughout the park, collects somewhere again into small streams and then emerges from the rock face. In the case of the Emerald Pools, this takes the form of small waterfalls. Their water flows into a series of circular rock pools called the Emerald Pools. They got their name because of their emerald color.

The Narrows
The Narrows are at the end of Zion Canyon. From the shuttle's final stop, Temple of Sinawava, it's a 30- to 40-minute walk to this gorge on the Virgin River. Here you walk through the river itself, since the steep walls do not allow a path along the bank at this point. The water is more than waist deep in places, so you have to swim in places. At the end of the narrows is Chamberlain Ranch. One to two days should be planned for the hike through. The 25km walk through the river is very strenuous as most of it is in the river itself. The walk-through must be registered at the visitor center at the backcountry desk. In the spring, no permission is granted because of the snowmelt and the associated water level. Even in summer, flash floods can occur due to violent thunderstorms. The thunderstorms do not have to come down in the park itself; the water may also come from the Colorado Plateau.

Kolob Arch
Depending on the measurement, the Kolob Arch shares the attribute “longest natural stone arch” with the Landscape Arch in Arches National Park. The mean value of the last measurements of the Kolob Arch is 89.6 m and thus exceeds the Landscape Arch by 1.2 m.

The Kolob Arch can only be reached via two hiking trails (22 km and 27 km in length). The arch itself sits right in front of a large, sheer cliff, so its view isn't as spectacular as other free-standing arches. A second natural rock arch is the Crawford Arch.

Checkerboard Mesa
At the park's east entrance is the Checkerboard Mesa, a mesa formed of Navajo Sandstone. Deep vertical grooves and chimneys and horizontal bands cut through the mountain's flanks. The bands form along the layer boundaries through weathering and erosion along different sedimentation layers. The vertical troughs can only be observed on the north side, since the snow melts more slowly here and they are widened by running water and frost erosion.
