Tucked away on the western coast of Sri Lanka, Anawilundawa — also known as the Annaiwilundawa Tanks Sanctuary — is one of the island's most quietly remarkable wetland habitats. Sitting within the Puttalam District, this sanctuary has earned international recognition as a wintering ground for migratory water birds, drawing attention from naturalists and wildlife enthusiasts alike.

The short film captures the sanctuary's character: still waters reflecting sky and greenery, the unhurried rhythm of wetland life, and the rich biodiversity that makes this corner of Sri Lanka so ecologically significant. For those who appreciate nature in its less-visited forms, Anawilundawa offers a glimpse of a landscape shaped by water, season, and migration.

A Sanctuary of International Importance

What sets this sanctuary apart is its role in the broader story of bird migration across Asia. Season after season, migratory water birds arrive here to winter, making the wetland a critical stopover and resting ground on their long journeys. The diversity of species that gather in and around these tanks underscores why the site is regarded as internationally important — not just a local treasure, but a significant node in a continent-wide ecological network.

Wetlands, Tanks, and Biodiversity

The sanctuary takes its character from a series of ancient irrigation tanks, a landscape feature common to Sri Lanka's northwest. These man-made reservoirs, over time, have become thriving ecosystems in their own right, supporting aquatic plants, fish, reptiles, and a remarkable variety of birds. Birdwatching here rewards patience — the sanctuary's calm, undisturbed environment encourages species to linger rather than flee.

Getting There and Nearby Attractions

The sanctuary lies close to Puttalam City, the main urban hub of the district, making it accessible for travellers exploring Sri Lanka's northwest. Visitors interested in exploring similar protected landscapes across the country will find that Sri Lanka's National Parks collectively offer a wide spectrum of ecosystems, from dry-zone forests to coastal wetlands such as this one.
