Bengal tigers in the Sundarbans are unique for their ability to drink saline water.
The forest covers approximately 10,000 square kilometers, with about 40% located within India.
Mangrove trees here utilize pneumatophores, or breathing roots, that protrude above the mud to intake oxygen.
The park is home to the world's largest population of the estuarine crocodile.
The Sundari tree (Heritiera fomes), from which the forest derives its name, provides high-quality timber.
The region experiences two high tides and two low tides every 24 hours.
It is the only mangrove forest in the world inhabited by tigers.
The complex tidal creek system changes constantly due to heavy siltation and erosion.
Sundarbans National Park is the world’s largest contiguous mangrove forest, designated as a UNESCO World Heritage site. Located in the Ganges Delta, the preserve spans the border between India and Bangladesh. The area is defined by a complex network of tidal waterways, mudflats, and salt-tolerant mangrove trees. It serves as a critical habitat for the endangered Bengal tiger, which has adapted to a semi-aquatic lifestyle. The ecosystem supports high biodiversity, including saltwater crocodiles, spotted deer, and the Irrawaddy dolphin. Visitors access the park exclusively via boat from designated entry points like Gosaba. The park's hydrological regime is dominated by daily tidal cycles, which regularly submerge large portions of the forest floor.
The Sajnekhali Watchtower provides an elevated vantage point overlooking the confluence of the river channels.
Hire a government-registered guide and boat operator to ensure compliance with forest department safety regulations.
Pack lightweight, breathable, and full-coverage clothing to protect against both tropical sun and insect bites.
Carry high-quality binoculars to view wildlife from the mandatory distance required by park authorities.
Do not attempt to walk on the forest mudflats or beaches, as they are high-risk zones for crocodile attacks and tiger sightings.
The park remains open year-round, but specific core areas may close temporarily during monsoon season or periods of extreme weather conditions.
Strict silence is required while cruising to avoid disturbing wildlife; plastic use is prohibited inside the forest zone.
