Established in 1954 around Senanayake Samudraya — Sri Lanka's largest reservoir, formed by damming the Gal Oya river — this eastern park stands apart as the only one in the country explored primarily by boat rather than jeep. Its signature sight is genuinely rare: wild elephants swimming between the reservoir's scattered islands, using their trunks as snorkels, a behavior scientists believe traces back to the very first elephants that swam to Sri Lanka from India. Years of wartime inaccessibility left it far less developed and far less crowded than Yala or Udawalawe, giving it a wilder, more untouched feel.

Wildlife safarisNature & viewpoints

Best time to visit

Dry season, roughly June to September, when water levels are lower and elephants gather more predictably near the shrinking shoreline.

Visitor tip

Boat and park access are weather-dependent; use authorized guides and operators.

Local pick

Combine the boat safari with a visit to Dambana, a nearby Vedda indigenous village, for a side of Sri Lanka most itineraries skip entirely.
