Inscribed on the UNESCO World Heritage list in 1987 and the home land of the Royal Bengal Tiger, it is a marshy stretch of land located in the Sunderban Delta of the state of West Bengal in India and extends into Bangladesh. It is bordered by the Ganges in the Indian region and the Brahmaputras in the Bangladesh region. The Sundarbans Wildlife Sanctuary, the world's largest estuarine sanctuary is really worth a visit.
It derives its name from the Sundari trees once found in the region.With a series of densely forested islands and saline water channels, Sundarbans is home to 270 Royal Bengal Tigers along with the spotted deers, wild pigs, monkeys, herons, kingfishers and white-bellied eagles. The other wild animals found in the Sundarbans National Park are estuarine terrapins, Olive Ridley turtles, estuarine crocodiles, Ganges dolphins, water monitors and a wide variety of birds, fish and crustaceans. One of the major tourist attractions is the Sajnekhali Visitors' Centre, which has a crocodile enclosure, a shark pond, a turtle hatchery, and a Mangrove Interpretation Centre.
Sundarbans National Park has large mangrove forests. The commonly identifiable vegetation that grow in the dense mangrove forests at the Sundarbans are salt water mixed forest, mangrove scrub, brackish water mixed forest, littoral forest, wet forest and wet alluvial grass forests.The main highlights of the park, when it comes to flora are Heritiera fomes, Excoecaria agallocha, Ceriops decandra and Sonneratia apetala. Sterculiaceae and Euphorbiaceae are the main species of the mangroves found in SundarbansTigers remain the most scintillating wildlife found here. But there are several other reasons too which will pull one to the deltaic region like the river terrapin (Batagur baska), Indian flap-shelled turtle (Lissemys punctata), peacock soft-shelled turtle (Trionyx hurum), yellow monitor (Varanus flavescens), water monitor (Varanus salvator) and Indian python (Python molurus) are some of best.
