The Sundarbans is a cluster of low-lying islands in the Bay of Bengal, spread across India and Bangladesh, famous for its unique mangrove forests. This active delta region is among the largest in the world, measuring about 40,000 sq km. Its a  vast forest in the coastal region of the Bay of Bengal and considered one of the natural wonders of the world. Located in the delta region of Padma, Meghna and Brahmaputra river basins, this unique forest extends across Khulna, Satkhira, Bagerhat districts of Bangladesh and South 24 Paraganas , North 24 Parganas districts of West Bengal, India. World's largest coastal mangrove forest lies in this sector, with an area of about 10,000 Sq kilometer, of which about 6,000 Sq kilometer are located in Bangladesh and about 4,000 Sq kilometer in India. Though uninterrupted landscape, it has been listed separately in the UNESCO World Heritage List as Sundarbans and Sundarbans National Park for Bangladesh and Indian parts of the Sundarbans.

The Sundarbans is a network of marine streams, mud shores and mangrove forests. In the mangroves salinity level is higher than the inland forests with freshwater swamp. The Sundarbans basically named after Sunadri, one of the acstatic flora and also enriched by gewa, goran and keora all of which present prominently throughout the area. Withing the fauna this place is renouned as motherland of Royal Bengal Tigers. Apart from that, the  region  contain numerous endangered species of wildlife globally threatened wildlife species such as the estuarine crocodile (Crocodilus porosus), Royal Bengal tiger (Panthera tigris), Water monitor lizard (Varanus salvator), Gangetic dolphin (Platinista gangetica), and olive ridley turtle (Lepidochelys olivacea). Birds and reptiles, camot, chital, crocodile, snakes of many variety are seen here. Despite a total ban on killing or capturing of wildlife other than fish and some varients, it appears that there is a consistent pattern of depleted biodiversity and loss of species in the current century, and that the ecological quality of the forest is declining. The area is covered with many observatory as well as view points and tourist attractions. Some of them are Neti Dhopani, Do banki,  Bakhhali / Frazergunj / Henry’s Island / Diamond Harbour / Raichak,  Sudhanyakhali,  Pirkhali, Gazikhali, Noubanki, Panchamukhani, Deul Varani, Chargheri Char,  Sundarban Tiger Project,  Bono Bibir Pala,  BurirDabri, Kumirmari, MorichJhapi,  Godhkhali, Canning,  Sajnekhali,  Mangrove Interpretation Centre,  Kumirmari watchtower,  Kakdip, Gangasagar etc.

Administration and management of Sundarban National Park in West Bengal is looked after by the Directorate of Forest. In Banglaesh A new Forest Circle headed by Chief Conservators of Forests is responsible to preserve the forest. Despite preservation commitments from both Governments, the Sunderban & Mangrove forest is under serious threat from both natural and manmade sources. In 2007 the landfall of Cyclone Sidr damaged around 40% of Sundarbans. Rising sea level  with increased salinty level with and reduced freshwater supply is the real threat for the forest. 

Communitaion:  Major communication inside the forest is through boats or steamers. There are several starting points for Sundarban trip as  Godhkhali, Canning etc. Upto the points mentioned its motorable. After that the entire trip is covered by Boats / Steamers.
