Factfile
Formed by the union of three mighty rivers—Ganga, Brahmaputra and Meghna, the extensive Sundarbans delta covers an area of 38,500 sq km, with a major portion of it spreading into Bangladesh.
The Indian part of the delta is home to the Sunderbans National Park, declared a UNESCO World Heritage Site in 1987.
Made up of 54 small islands, swamps and an intricate network of waterways and canals, this 2,585-sq km park is the world’s largest estuarine mangrove forest.
Besides the forest itself, the tiger reserve, crocodile sanctuary and Sajnekhali Bird Sanctuary are major wildlife attractions.
