Uda Walawe National Park

Uda Walawe exists because of a dam. When the Walawe River was blocked in the late 1960s to create a reservoir for irrigation and hydropower, the flooding displaced elephant herds and destroyed their habitat, and the Sri Lankan government responded by declaring a new national park specifically to give those displaced animals, and the reservoir’s own catchment, somewhere protected to be.

Born From a Dam Project

The story of Uda Walawe begins with an act of large-scale infrastructure development rather than conservation. Between 1967 and 1969, engineers dammed the Walawe River as part of Sri Lanka’s post-independence irrigation and hydroelectric programme, creating a substantial reservoir that flooded large areas of dry-zone forest and grassland. That flooding displaced elephant herds and other wildlife en masse, and destroyed the habitat many depended on, alongside triggering widespread logging and slash-and-burn chena farming in the surrounding cleared land.

In response, the government officially declared the area a national park on 30 June 1972, Sri Lanka’s fifth, under the Fauna and Flora Protection Ordinance. Its dual purpose was explicit from the start: protect the reservoir’s catchment area, and provide a home for the elephants displaced by its construction. A number of deliberate “elephant drives” were conducted in the years after, herding animals from developed land into the new park, and an electric fence was later built along the southern boundary to manage the boundary between park and farmland.

Grasslands Born From Farming

One of the park’s more ironic details is that its open, elephant-friendly grasslands are themselves a legacy of the very farming activity the park was created to end. Areas cleared for chena cultivation before the park’s declaration became colonised by Guinea grass, an imported fodder grass that spread widely after being introduced in the 1800s. That grass-dominated landscape, unintentional as its origins were, turned out to be ideal for elephant viewing, since it offers unobstructed sightlines across open plains rather than the dense forest cover that makes elephant spotting harder in parks like Wilpattu.

Sri Lanka’s Most Reliable Elephant Safari

Uda Walawe is widely considered the best place in Sri Lanka to see wild Asian elephants consistently, year-round, with an estimated 500 elephants living within the park, sometimes gathering in herds of up to 100 individuals around the reservoir’s shoreline. Beyond elephants, the park supports water buffalo, wild boar, spotted and sambar deer, jackals, toque macaques and grey langurs, along with over 180 recorded bird species, including painted storks, openbill storks and lesser adjutants. Leopards and sloth bears are present too, though sightings require considerably more luck than at Yala or Wilpattu.

Visiting Tips

• Book a jeep safari through a licensed operator or lodge near the park entrance; early morning or late afternoon drives generally offer the best sightings.
• Combine a park safari with a visit to the Elephant Transit Home for a broader elephant-focused day.
• The park’s smaller size and open terrain generally make for more predictable elephant sightings than at larger, denser parks.
• Uda Walawe pairs naturally with a wider South Coast itinerary, being roughly equidistant between Colombo and the beach towns further south.
