The Kadalundi Bird Sanctuary is spread over a cluster of islands in a scenic area surrounded by hillocks where the Kadalundi River flows into the Arabian Sea. The place is locally known as Kadalundi Nagaram.

This virgin land is the abode of a hundred species of native birds and over 60 varieties of migratory birds that flock here in large numbers during February-March.

A hillock nearby, which is 200 m above sea level, offers a splendid view of the river mouth and the sea. Kadalundi is also known for a wide variety of fish, mussels and crabs.
