About Sundarbans

The Sundarbans mangrove delta sprawls across 10,000 square kilometres—a labyrinth of channels, islands, and waterways where Bengal tigers hunt from water and land. The world's largest tiger population (around 500) stalks these waters; saltwater crocodiles, river dolphins, and monitor lizards complete the ecosystem. Tours depart from Khulna or Mongla by boat.

The Sundarbans is the world's largest mangrove forest, a vast, tide-flooded wilderness straddling Bangladesh and India that's home to the elusive Bengal tiger alongside saltwater crocodiles, spotted deer and a huge range of birdlife. Exploring it means slow boat journeys through narrow tidal channels, with sightings never guaranteed but the landscape itself reason enough to visit.

Frequently asked questions

When is the best time to visit the Sundarbans?

November to February offers the most comfortable weather and best wildlife visibility; the monsoon season makes river travel more difficult.

How do I visit the Sundarbans?

Multi-day boat trips departing from Khulna or Mongla are the standard way to explore, with overnight stays aboard the boat itself.

Is the Sundarbans dangerous?

Tiger encounters with boat-based tourists are extremely rare, but visitors should always stay with licensed guides and follow forest department guidelines.

What wildlife besides tigers can be seen?

Spotted deer, saltwater crocodiles, rhesus macaques, and an exceptional range of waterbirds including kingfishers and eagles are commonly spotted.

Traveler reviews

★★★★★

Didn't see a tiger but the boat journey through the mangroves at dawn, with mist rising off the water, was magical on its own. Saw crocodiles and dozens of bird species.

Hasan M. · January 2024

★★★★☆

A genuinely wild place — three days on a small boat with no phone signal and just the sounds of the forest. Worth going for the experience even without a tiger sighting.

Lucy F. · December 2023

★★★★☆

Karamjal's boardwalk was a good gentle introduction before our longer boat trip deeper into the forest, where the channels narrow and feel truly remote.
