Bundala National Park is one of the smallest national parks in Sri Lanka but quite unique. The national park is adjoined to a protected coastal area in the southeastern part of the country. It consists of marshes, lagoons, and sand dunes.

It is also the first wetland in the country to be declared in 1991 as Ramsar site in recognition of its importance to areas of high biodiversity value, including wetlands. The park is also considered an internationally important habitat for migratory birds. Bundala has about 230 indigenous and migrant bird species, including many wetland species.
