Lying in the basin of the Heda Oya, 16km inland from Pottuvil on the east coast, Lahugala has a total area of 1,554 hectares, encompassing three tanks (ancient reservoirs), Lahugala, Kitulana and Sengamuwa. These tanks are largely silted up and support an abundance of beru grass – the Asian elephant’s favourite.
Nearby to Lahugala is the historic sight of Magulmahavihara, built for the King Kavantissa’s marriage to Viharamaha Devi. A visit to this monument is possible to combine with a trip to Lahugala National Park.
As the park lies in the dry zone, the vegetation surrounding the tanks is a dry mixed evergreen forest with scrubs. Beru, a tall reedy grass, covers the tanks. The park is traditionally used as a feeding ground by elephants, with herds of up to 150 known to be observed between June and August. Other mammals include endemic toque macaques, grey langurs, sloth bears, golden jackals, the Indian muntjac and spotted deer among others. The birdlife is diverse and includes a variety of waterfowl, raptors and the usual dry zone forest birds.
