Area: 30,000 ha
Brasília National Park (Parque Nacional de Brasília, often called Água Mineral) is a large protected area of Cerrado (Brazilian savanna) just outside the capital, covering roughly 42,000–42,400 hectares. Created in 1961 to protect water sources for the new capital, it safeguards springs, gallery forests, typical Cerrado vegetation, and significant biodiversity while serving as a popular urban-adjacent recreation spot.
Location & Getting There
The main entrance is about 10 km from
central Brasília (Plano Piloto) via the Estrada Parque Indústria e
Abastecimento / Via EPIA (around BR-450/EPIA Norte area). Public buses
run from the main bus terminal (Rodoviária do Plano Piloto). Taxis,
Uber, or a private car work well; parking is available near the
pools/visitor areas (with priority spots for disabled visitors, elderly,
pregnant women, etc.). There is also a secondary access point (Portal do
Arco Brasília near BR-080) mainly for through-hikers connecting to
Floresta Nacional de Brasília.

pricing, as it can change.
Main Attractions & Trails
The park
features two main visitation zones: Água Mineral (pools + Capivara area)
and Cristal Água (trail system).
Trilha da Capivara: Short, easy,
mostly shaded circular trail (~1.3–1.8 km, about 20–30 minutes). Ideal
for families, beginners, birdwatching, and environmental education.
Access near the Pedreira area. Occasionally closed for maintenance or
used for guided Forest Bathing (Banho de Floresta) sessions (free with
park entry, limited spots, usually Saturdays mornings and Tuesdays
afternoons—registration often required).
Sistema Trilhas Cristal
Água: Color-coded routes of increasing length and difficulty:
João de
Barro (~5 km, pink)
Arara-canindé (~10 km, orange)
Seriema (~15
km, blue)
Mutum (~18 km, yellow)
Suitable for hiking or mountain
biking (shared use—cyclists yield to walkers and wildlife). Landscapes
mix typical Cerrado and gallery forest; some views of the city in the
distance. Access generally until early/mid-afternoon.
Arco
Brasília: Longer crossing (~21 km from the Cristal Água start) linking
the National Park to Floresta Nacional de Brasília, marked with
distinctive footprints. For experienced hikers or cyclists; early start
required.
Ilha da Meditação: Quiet contemplative area by a lagoon.
Swimming is not allowed due to risks and water infrastructure. Good for
photography and relaxation.
Other: Visitor center/education area,
historical sections of the old Estrada Real Santa Luzia-Contagem
(colonial gold route), and natural viewpoints.
Wildlife & Flora
Expect classic Cerrado vegetation: twisted trees, grasses, gallery
forests along streams, and seasonal flowering. Notable (and often
threatened) fauna include the maned wolf (lobo-guará), giant anteater
(tamanduá-bandeira), giant armadillo, ocelot, tapir, puma, and various
birds (e.g., campo jay, yellow-faced parrot). More commonly seen are
capybaras, birds, and smaller mammals. Sightings are better in the dry
season; stay on trails, do not approach or feed animals, and be aware of
snakes and insects.
Best Time to Visit
Year-round is possible.
Dry season (roughly May–September) offers easier trails, clearer views,
and better wildlife visibility, with milder mornings. Wet season
(roughly October–April) brings greener vegetation and more flowers/birds
but muddier paths and higher risk of storms. Arrive early (especially
weekends) to beat crowds and heat. Mornings are cooler and quieter.
Practical Tips
What to bring: Plenty of water and snacks (food
sales are limited or irregular; no cooking/grilling), sturdy closed-toe
shoes or trail shoes (avoid sandals), sunscreen, hat, insect repellent,
light rain layer if needed, and personal medications. Clean shoes/bikes
before entry to avoid introducing exotic seeds.
Rules & restrictions:
No pets (except service animals), no alcohol, no smoking/fire/glass
containers, stay strictly on marked trails, pack out all trash, no
camping or overnight stays, no loud music. Minors under 18 need adult
supervision on trails; under-12s cannot enter alone. Respect shared
trail etiquette.
Safety: Risk of sun exposure/dehydration, wildlife
encounters, falls, lightning, or falling branches. No on-site rescue
service—call 192 (SAMU) or 193 (firefighters) in emergencies. Tell
someone your plans for longer trails. Speed limit inside is 40 km/h;
yield to animals and pedestrians.
Facilities: Restrooms,
showers/changing areas, and drinking fountains near main areas
(availability tied to open attractions). Lifeguard/first-aid posts at
pool areas when operating. Bike racks available.
Accessibility:
Priority parking and some easier paths; longer trails are natural and
more challenging.
Geomorphology and Terrain
The park lies in the domain of plateaus
on sedimentary structures (Planaltos em Estruturas Sedimentares
Concordantes), specifically within the Chapadas of the Federal District
and related units. Three main geomorphological units are recognized:
Chapada da Contagem: The highest residual plateau surface (part of
the broader South American planation surface). Within the park it
generally ranges from about 1,200–1,279 m; the nearby high point
Rodeador reaches ~1,302 m. It features broad, gently undulating to flat
tops.
Depressão do Paranoá: The spatially dominant intermediate
dissection zone, typically 1,000–1,200 m, with gently undulating relief,
broad interfluves, and slopes often of 5–10°.
Encosta da Contagem:
The transitional slopes and escarpments (with steeper steps linked to
quartzite outcrops) connecting the chapada to the depression.
Overall elevation across the park is roughly 1,000–1,300 m. The terrain
is an undulating plateau with limited steep relief except along the
escarpment edges. Soils are predominantly reddish latosols, with
alluvial and hydromorphic soils in wetlands, marshes, and along
watercourses.
Geology
The park is situated in the eastern
sector of the Tocantins Structural Province and the south-central part
of the Brasília fold belt. Dominant rocks belong to the Mesoproterozoic
Paranoá Group (depositional sequence roughly 1,350–950 Ma), a thick
(~1,600 m) package of metasediments deposited in a passive-margin
setting. Key lithofacies include basal slates (ardósias, intensely
fractured), metarhythmites (with clayey, silty, and sandy
intercalations), and quartzites that cap higher surfaces and form
resistant escarpments. Limestones also occur. These formations produce
many springs, caves, and high spring density relative to similar Cerrado
areas. Aquifers include both porous and fractured domains, with features
such as pseudo-dolines (“três buracos”) linked to subsurface flow.
Climate
The climate is tropical savanna (Köppen Aw). Mean annual
temperature is around 20.6–22 °C (with absolute maxima historically in
the low 40s °C and minima occasionally near or below 5–8 °C). Annual
rainfall averages about 1,500–1,675 mm, of which ~84% falls in the wet
season (October–April; wettest months typically November–January). The
dry season (May–September) brings very low precipitation and relative
humidity that can drop below 15%. Elevation moderates extremes, and
easterly winds are common.
Hydrology
The park is a critical
headwater protection area. It safeguards the basins of streams that form
the Santa Maria Reservoir (Barragem de Santa Maria), which supplies a
substantial share of the Federal District’s potable water—historically
cited around 25%, with recent figures in the 19–29% range depending on
the source and system integration. The reservoir (capacity on the order
of 61 billion liters) has high water quality because of the surrounding
protected land with minimal human use in the immediate catchment. Key
streams include Santa Maria, Torto, Bananal, and others (tributaries
ultimately related to the Paranoá system and, in parts of the broader
area, the Maranhão). Numerous springs give the park its “Água Mineral”
nickname. Visitor pools near the entrance formed from former
sand-extraction pits along Córrego Acampamento and are fed by clear
groundwater.
Ecosystems and Vegetation
The park protects a
representative mosaic of Central Plateau Cerrado. Dominant vegetation is
cerrado sensu stricto. Other types include:
Gallery forests (mata
de galeria, both swampy/pantanosa and non-swampy)
Veredas (wet palm
wetlands dominated by buriti, Mauritia flexuosa)
Cerradão, dry forest
(mata seca)
Various grasslands: campo sujo, campo limpo, campo
rupestre, campo úmido, and campo de murundus (termite-mound grasslands)
These form a classic Cerrado mosaic adapted to seasonal drought and
fire, with deep-rooted plants, thick bark, and specialized wetland
communities along watercourses.
Fauna
Biodiversity is high and
includes many threatened or endemic Cerrado species. Notable mammals
include maned wolf (Chrysocyon brachyurus), giant anteater (Myrmecophaga
tridactyla), giant armadillo (Priodontes maximus), pampas deer, jaguar,
puma, ocelot, bush dog, and others. Birds are diverse (hundreds of
species recorded in the broader area), including greater rhea, toco
toucan, red-legged seriema, curl-crested jay, and various raptors and
endemics. The park also supports reptiles, amphibians, fish (including
small isolated headwater populations), and invertebrates. Overall animal
diversity is often cited as exceeding 1,000 species.
