Anawilundawa Wetland Sanctuary
A Ramsar listed wetland of six ancient tanks between Chilaw and Puttalam, full of herons, storks, pelicans and, from October to April, migrant birds.
Anawilundawa, between Chilaw and Puttalam, is a chain of six ancient irrigation tanks surrounded by marsh, scrub, paddy fields and mangroves, and it is one of Sri Lanka's internationally protected Ramsar wetlands. The tanks were built centuries ago to store water for farming, and over time they have become one of the richest bird habitats on the west coast.
Birdwatchers come here for the sheer number and variety of species. Herons, egrets, cormorants, spot billed pelicans, painted storks, open billed storks and purple swamphens are everywhere, and in the right season the water is covered with ducks, waders and other visitors. Look closely along the banks and you may also see monitor lizards, crocodiles, otters and plenty of butterflies and dragonflies.
The best time to visit is from around October to April, when migrant birds arrive from the north and join the resident species. At any time of year, go early in the morning, roughly from sunrise to 9am, or in the late afternoon, when the birds are most active and the heat is gentler. In the middle of the day, the tanks can feel quiet.
You can walk along the tank bunds, which give good views over the water, but keep to the paths and walk quietly so you do not disturb the birds. Bring binoculars, a hat and water, and wear muted colours. Anawilundawa is a great stop on the drive between Colombo and Kalpitiya, and it combines easily with Munneswaram Temple near Chilaw.
