Understand
The Sundarbans are the largest littoral mangrove belt in the world, stretching 80 km 50 mi into the Bangladeshi and Indian hinterland from the coast. The Sundarbans has been declared a UNESCO World Heritage Site. The forests aren't just mangrove swamps though, they include some of the last remaining stands of the mighty jungles which once covered the Gangetic plain. The Sundarbans cover an area of 10,500 sq km, of which about one-third is covered in water/marsh areas. Since 1966 the Sundarbans have been a wildlife sanctuary, and it is estimated that there are now 400 Royal Bengal tigers and about 30,000 spotted deer in the area.
Flora and fauna
Royal Bengal Tigers are the main draw, but you can also spot Saltwater Crocodiles, various primates, leopards, King Cobras and Indian Cobras.
Sundarbans is home to many different species of birds, mammals, insects, reptiles and fishes. Over 120 species of fish and over 260 species of birds have been recorded in the Sundarbans. The Gangetic River Dolphin Platanista gangeticus is common in the rivers. No less than 50 species of reptiles and eight species of amphibians are known to occur. The Sundarbans now support the only population of the Estuarine, or Salt-Water Crocodile Crocodylus parasus in Bangladesh, and that population is estimated at less than two hundred individuals.
The park is also home to sea gypsy fishing families who catch fish using trained otters.
