The Anawilundawa Bird Sanctuary is situated in the Puttalam district in the North Western province of the country; between Chilaw and Puttlam – to be more specific - it is situated between the coast and the Chilaw-Puttlam railway line.
The uniqueness of Anawilundawa is its immediate proximity to three vastly different ecosystems; the coast, the mangroves and the fresh water tanks making it one of the six RAMSAR Wetlands in Sri Lanka. This unique ecological setting has made it a favorable nesting and breeding ground for hundreds of species of birds.
