Open: 6:30am- 6:30pm
Udawalawe National Park is a significant protected area in southern Sri Lanka, renowned for its diverse landscapes shaped by its position on the boundary between the island’s wet and dry climatic zones. Established on 30 June 1972, the park was created primarily to safeguard wildlife displaced by the construction of the Udawalawe Reservoir (dammed in 1971 on the Walawe River) and to protect the reservoir’s catchment area. It straddles the Sabaragamuwa Province (western half, primarily in Ratnapura District) and Uva Province (eastern half, in Monaragala District), with coordinates centered around approximately 6°26′18″N 80°53′18″E. The park lies roughly 165–170 km southeast of Colombo, near the towns of Embilipitiya and Udawalawe.
Best Time to Visit
Dry season (May–September, and
December–March): Optimal for wildlife viewing. Vegetation thins out,
animals concentrate around waterholes and the reservoir, and spotting is
easier. Lower rainfall means more comfortable conditions.
Wet season
(October–April): Lusher greenery, more migratory birds (November–March
peak), and potential for baby elephant sightings (births often
October–January). Roads can get muddy, and animals disperse more, but
sightings remain strong.
Time of day: Morning safaris (starting
~5:30–6:00 AM) are widely recommended—cooler, animals more active
(elephants grazing), golden light for photos, and fewer crowds
initially. Afternoon safaris (~2:00–2:30 PM) work well for reservoir
visits at dusk but can be hotter and busier. Full-day options allow
deeper exploration.
The park is open daily from ~6:00 AM to 6:00 PM.
Wildlife Highlights
Elephants: The star attraction. High density
means near-guaranteed sightings of herds, mothers with calves, and
bulls. They are habituated to vehicles but still impressive.
Other
mammals: Water buffalo, spotted deer/sambar, wild boar, golden jackals,
toque macaques, grey langurs. Leopards are rare (fewer than Yala; treat
any sighting as a bonus, more likely at dawn/dusk with a skilled guide).
Birds: Over 180–200 species, including peacocks, Malabar pied hornbills,
white-bellied sea eagles, kingfishers, bee-eaters, and migrants.
Reptiles: Mugger crocodiles, monitor lizards.
Expect a mix of open
savanna-like areas near the reservoir and denser patches. Jeeps spread
out inside the park, but popular spots can get crowded with vehicles.
How to Get There
From Colombo: 4–5 hour drive (~200 km
southeast).
From Ella: ~2–3 hours.
From southern beaches (Mirissa,
Galle, Unawatuna): Similar 2–4 hours.
Best options: Private
driver/taxi (most convenient; book via hotel or apps), or bus to
Embilipitiya/Udawalawe town then tuk-tuk. No self-drive in the park.
Base yourself in Udawalawe or nearby Embilipitiya for easy access. Many
hotels offer pickup/drop-off within ~5 km of the gate.
Booking a
Safari: Practical Tips
Format: Open-top 4x4 jeeps with licensed
driver-guide (mandatory; no self-drive). Half-day (3–4 hours) or
full-day. Private jeeps (max ~6 people) are strongly recommended for
flexibility, quieter experience, and better wildlife respect over larger
group tours.
Cost (approximate 2026; confirm current rates):
Foreign adult entrance: ~$25–42 USD/person (plus service charge
~$8/group, VAT, jeep fee). Children 6–12 half price; under 6 often free.
SAARC rates lower. Pay in LKR (cash often needed).
Jeep + guide:
~4,500–6,000+ LKR for half-day.
All-inclusive private tour (with
pickup/entrance): Often $50–85+ per person depending on group size. Book
via hotel, GetYourGuide, Viator, or local operators for convenience.
Tips: Book in advance, especially peak season. Private is worth it
to avoid convoy chaos. Ethical operators follow park rules (no
off-roading, engine off near animals, no feeding). Online permits via
Department of Wildlife Conservation site if self-arranging.
What
to Bring and Wear
Essentials: Binoculars, camera with zoom (200mm+),
sunscreen (SPF 50+), insect repellent, hat, sunglasses, light layers
(cool mornings, hot days), reusable water bottle, snacks, cash
(entrance/tips), phone/power bank.
Clothing: Lightweight, neutral
colors (khaki, greens, browns to blend in), comfortable closed shoes or
sturdy sandals for any short stops. Modest coverage for sun protection.
Don't bring: Drones (restricted), flash photography, loud items,
single-use plastics.
On-the-Ground Experience and Rules
Expect
bumpy tracks, dust, and heat. Safaris are immersive but touristy—drivers
communicate via radio for sightings, leading to occasional vehicle
clusters.
Rules: Stay in vehicle (except designated areas), no
littering, respect distance (guides know limits), quiet voices, no
feeding animals. Guides share excellent info on behavior and
conservation.
Combine with the Udawalawe Elephant Transit Home
(nearby orphanage for rescued calves; feeding times ~9 AM, 12 PM, 3 PM,
6 PM) for a full day, but prioritize the wild park.
Where to Stay
Options range from budget guesthouses to eco-lodges:
Eliyanth
Udawalawe or similar boutique spots: Treehouse vibes, pools, nature
immersion, safari booking help.
Others: Waraka Udawalawe, Jungle
Paradise, Centauria Wild. Stay near the park for early starts.
Overnighting allows morning/afternoon safaris without long transfers.
Day trips from farther away are possible but tiring.
Pros, Cons,
and Comparisons
Pros: Elephant-focused reliability, affordability,
accessibility, scenic reservoir views, good for families/birders.
Cons: Can feel crowded at hotspots; elephants are habituated (less
"wild" behavior than remote parks); leopards rarer than Yala.
Vs.
Yala: Udawalawe wins for elephants; Yala for leopards/big cats and
variety. Many do both.
Prehistoric and Ancient Human Presence in the Walawe
River Valley
Archaeological evidence shows the Walawe River basin
(historically called Vana Nadi) has supported human activity for
millennia. Prehistoric skeletal remains believed to be about 28,000
years old were discovered at Bellanbendipelessa near Handagiriya (in the
northwestern corner of what is now the park). Settlements around
Balangoda, which straddles the western edge of the basin, date back to
approximately 6,500 B.C.
During the early historic period, the area
was part of the ancient Ruhuna kingdom. The Mahawamsa chronicles mention
Magama as an important city in the middle of the present-day Udawalawe
Irrigation Project area as early as 246 B.C. Kings such as Dutugemunu
(161–137 B.C.) and Valagamba (104–76 B.C.) developed extensive paddy
cultivation and anicut-based irrigation systems upstream in the Walawe
basin. Nearby sites like Kaltota (ancient Kalathitha Pura, ~2nd century
B.C.) contain ruins of Buddhist temples (e.g., Budugala Purana Rajamaha
Viharaya and Kuragala Purana Rajamaha Viharaya) and evidence of advanced
iron-smelting furnaces powered by monsoon winds that operated from the
3rd century B.C. to the 12th century A.D.
Handagiriya (ancient
Chandana Grama) served as a provincial center with multiple ancient
tanks (only five of which remain functional today). Sri Lankan legends
and the Ramayana even associate the area with King Ravana (~1500 B.C.),
though this remains mythological.
The basin prospered until around
the 13th century, after which factors such as invasions, malaria, and
migration to the wet zone led to depopulation. By the Kandyan period
(1524–1815), settlements were sparse, and the area relied on ancient
tanks for water. British colonial records from 1818 (after an
insurrection) describe the Walawe basin as thick jungle with malaria and
very low population. A major drought in 1866 highlighted the need for
large-scale irrigation, but British efforts remained limited until the
early 20th century.
Colonial Era to Post-Independence Development
(Late 19th–Mid-20th Century)
Under British rule, the Walawe plain
remained largely underdeveloped and sparsely populated, with local
communities practicing chena (slash-and-burn shifting cultivation). By
the 1940s, colonial authorities began ambitious plans for the Walawe
River Basin Scheme to modernize agriculture.
After Sri Lanka’s
independence in 1948, the new government prioritized dry-zone
development for food security, land resettlement, and economic growth.
Surveys and feasibility studies intensified for the Uda Walawe
Irrigation and Resettlement Project (UWIRP), which aimed to irrigate
over 32,000 hectares and resettle thousands of landless families from
the wet zone.
Construction of the Udawalawe Reservoir (1960s)
The cornerstone of the UWIRP was the Udawalawe Dam, an earth-filled
embankment (approximately 3.9–4 km long and 36 m high) built across the
Walawe River. Tenders were invited in 1963 by the River Valleys
Development Board (RVDB), construction began in late 1964, and the
headworks were completed in 1967–1968 (some sources cite full reservoir
filling by 1968 or 1971). Two hydroelectric plants (total ~6 MW) were
commissioned in April 1969.
The reservoir covers about 34 km² with a
live storage capacity of ~240–268 million cubic meters. Its primary
purposes were:
Irrigation for double-cropping rice and other
crops across ~32,000+ hectares (right and left bank canals).
Hydropower generation.
Flood control.
Resettlement of around
12,000 landless families.
The dam flooded large areas of forest
and farmland, displacing wildlife (especially elephants) and submerging
trees—skeletons of which are still visible in the reservoir today. By
the time the park was declared, forest cover in the area had dropped
dramatically (from over 80% in 1956 to about 4% by 1972) due to chena
farming and project-related clearing.
Establishment of Udawalawe
National Park (1972)
To address the ecological fallout, the
government declared the surrounding area and reservoir catchment a
national park on 30 June 1972. The explicit goals were:
To provide a
sanctuary for wild animals displaced by the dam.
To protect the
reservoir’s catchment area from further degradation.
Local
farmers practicing chena cultivation were gradually relocated. The
resulting open grasslands (a legacy of former shifting agriculture)
combined with the reservoir created an ideal habitat for elephants and
water birds, making the park unique among Sri Lanka’s more densely
forested reserves. A pre-existing teak plantation below the dam remains
visible today.
The park is administered by the Department of Wildlife
Conservation (established in 1949). It lies at the boundary of the dry
and intermediate climatic zones, with plains, some mountainous areas
(Kalthota Range), and features like Diyawini Falls.
Post-Establishment Development and Conservation Milestones
1991–1998:
The Mau Ara tank was constructed inside the park boundaries as part of
ongoing irrigation expansions.
October 1995: The Udawalawe Elephant
Transit Home (ETH) was established within the park to rehabilitate
orphaned or abandoned elephant calves. It has successfully hand-reared
and released dozens of calves back into the wild (e.g., releases of nine
calves in 1998/2000 and eight in 2002). The ETH remains a major visitor
attraction and a flagship of Sri Lankan elephant conservation.
The park now supports a resident population of roughly 250 elephants
(plus transient herds), along with 184 bird species (33 migratory),
water buffalo, spotted deer, leopards, and other mammals. Its open
terrain guarantees frequent elephant sightings, boosting tourism
(hundreds of thousands of visitors annually in recent decades).
Challenges and Legacy
Like many protected areas born from development
projects, Udawalawe has faced ongoing issues: human-elephant conflict on
its borders, poaching, illegal logging/gem mining, encroachment,
invasive plants (e.g., Lantana camara), and occasional overgrazing.
However, it is widely regarded as a conservation success
story—transforming a disrupted landscape into a thriving wildlife haven
and a vital link in Sri Lanka’s protected area network.
Size and Boundaries
The park covers approximately
308.21 km² (30,821 hectares or 119 square miles), though some sources
cite a total extent of around 32,315 ha when including the full
reservoir at capacity. The Udawalawe Reservoir itself accounts for
roughly 3,400–3,405 hectares of open water at full supply level. The
boundaries encompass the lower and immediate catchment areas of the
Walawe River (Walawe Ganga) and the Mau Ara (Mau Aru) drainage basins.
The western edge follows the left bank of the reservoir in Ratnapura
District, while the eastern sector lies on the right bank in Monaragala
District. Northern boundaries reach the Kalthota Escarpment, and the
park includes surrounding lowlands and foothills.
Topography and
Landforms
Plains dominate the topography, creating an undulating
lowland landscape that gives the park its characteristic open,
savanna-like appearance. The average elevation is about 163 m (535 ft)
above sea level, with the core plains sitting around 100 m. The terrain
rises gently in places but features more pronounced relief along the
boundaries:
Western foothills: Ulgala rises to approximately
373–380 m.
Northern section: The Kalthota Range (or Escarpment) forms
a dramatic backdrop, with the spectacular Diyawini (or Diyawinne) Falls.
Internal features: Prominent rock outcrops such as Bambaragala and
Reminikotha punctuate the plains.
Overall range (per topographic
data): Minimum around 49 m near watercourses or low valleys; maximum up
to ~747 m on higher ridges or escarpment edges.
This moderate
elevation keeps the park in a tropical lowland setting, distinct from
the cooler central highlands just to the north. The open plains,
combined with scattered hills and escarpments, allow for excellent
long-distance visibility—ideal for wildlife observation.
Hydrology
Water is the defining geographical feature. The Udawalawe
Reservoir, a large man-made lake at the park’s heart, draws water
primarily from the Walawe River and its tributaries originating in the
Peak Wilderness Sanctuary and central highlands. It also receives input
from the Mau Ara system. The reservoir’s surface area fluctuates with
seasonal water levels, and submerged dead trees (remnants of pre-dam
forest) still stand as striking silhouettes, especially during lower
water periods.
Surrounding the reservoir are extensive marshes and
wetland fringes. Smaller water bodies, including the Mau Aru
reservoir/tank, add to the aquatic mosaic. Riverine habitats line the
Walawe River and tributaries, creating corridors of denser vegetation.
The park protects these drainage basins, ensuring the reservoir’s role
in irrigation and flood control while maintaining ecological integrity.
Geology and Soils
Geologically, much of the park lies within the
Vijayan Series—hard crystalline rocks from the pre-Cambrian era,
primarily gneisses and granites. There is a transitional influence from
Highland/Khondalite Series rocks toward the west and north near the
escarpment.
Soils reflect the topography and hydrology:
Well-drained reddish-brown earths predominate across the plains.
Poorly drained low-humic grey soils (gley soils) occur in valley bottoms
and low-lying areas.
Alluvial soils dominate along riverbeds and
watercourses.
Some areas feature solodized solonetz or other variants
influenced by seasonal flooding.
These soils, combined with past land
use, support the park’s current vegetation mosaic.
Climate
Udawalawe sits in Sri Lanka’s dry zone but on the boundary with the wet
zone, resulting in notable biodiversity. Annual rainfall averages 1,500
mm (about 59 inches), concentrated in two periods: the northeast monsoon
(October–January) and a shorter inter-monsoonal period (March–May). A
pronounced dry season occurs from February to March (sometimes extending
into September).
Temperatures remain uniformly high, with an annual
average of 27–28 °C (81–82 °F); daily highs can reach 37 °C and lows dip
to around 17.7 °C in cooler months. Relative humidity ranges from
70–83%. This tropical lowland climate, with seasonal rains feeding the
reservoir and grasslands, drives the park’s ecological dynamics.
Vegetation and Habitats Shaped by Geography
The combination of
topography, hydrology, climate, and historical human activity (former
chena/shifting cultivation) has produced a rich mosaic of habitats:
Grasslands (roughly 31–32% of the area) dominate the open plains,
featuring species like Guinea grass (Panicum maximum) and Imperata
cylindrica—key forage for elephants.
Scrub and thorn-scrub cover over
50%, creating savanna-like expanses interspersed with bushes (e.g.,
Grewia tiliifolia).
Dry mixed evergreen forest patches remain (canopy
up to ~30 m), with taller trees such as Palu (Manilkara hexandra),
Chloroxylon swietenia, and others.
Riverine forest along the Walawe
River features endemic species like Hopea cordifolia (Uva Mandora) and
Kumbuk (Terminalia arjuna).
Aquatic habitats include marshes, the
reservoir (with algae like Pediastrum and Microcystis), and wetland
fringes.
Minor areas include rock outcrops and small plantations
(e.g., teak south of the dam).
The transitional wet/dry location,
combined with the reservoir’s influence and open terrain from past
cultivation, creates an extraordinarily varied habitat within one
relatively compact park—ranging from arid scrub to lush riverine
corridors and expansive grasslands framed by the Kalthota Range.
