Nalaban Island: The 15 km Nalaban Island is within the Lagoon and is the core area of the Ramsar designated wetlands. It was declared a bird sanctuary under the Wildlife Protection Act in 1973. It’s the heart of the park where one can seen thousands of birds descending during the migratory season. The island disappears during monsoon season due to inundation, and post-monsoon, the island emerges again.

The vast lake harbours 225 species of fish, a wide variety of phytoplankton, algae and aquatic plants, and also supports over 350 species of non-aquatic plants. The other areas where high concentrations of birds are recorded are Gerasara, Parikud Island, and the western shores of the Northern sector.

Chilka Lake is one of the best bird watching spots in India, and is also popular for fishing and angling.
