Pulicat Lake is spread over an expanse of 350 square kilometres which is famous for attracting several rare species of migratory birds. It is the second largest saltwater lagoon after the Chilka Lake in Orissa. It is separated from the Bay of Bengal by a stretch of land known as Sriharikota Island. Pulicat Lake is a good option as a picnic spot for tourists, as the area is generally calm and serene, surrounded by the ambience of the lake and the large numbers of migratory birds.
The lake is also a destination of choice for birdwatchers as several rare species of migratory birds come to the lake during most times of the year. It is possible to go on a boat trip in the lake. The best bet is to rent a boat from one of the fishermen for as little as 500 rupees for a boat and go on a boat trip in the lake. Some of the notable species of birds that can be found here are waterfowl, pelicans, herons and flamingos.
