Puri
Asia's largest brackish water lagoon and India's premier birding destination, Chilika Lake is home to over a million migratory birds from Siberia, Iran, and Central Asia between October and March. Irrawaddy dolphins inhabit the Satapada area of the lake, making this one of India's most biodiverse day-trip destinations.
Satapada is the best dolphin-spotting area; Mangalajodi village is the top birding spot — plan your boat to visit both if time allows.
