Udawalawe National Park is a national park on the boundary of Sabaragamuwa and Uva Provinces in Sri Lanka. The park was created to provide a sanctuary for wild animals displaced by the construction of the Udawalawe Reservoir on the Walawe River, as well as to protect the catchment of the reservoir. The reserve covers 30,821 hectares of land area and was established on 30 June 1972. Before the designation of the national park, the area was used for shifting cultivation (chena farming). The farmers were gradually removed once the national park was declared. Udawalawe is an important habitat for water birds and Sri Lankan elephants. It is a popular tourist destination and the third-most visited park in the country.
