The Sundarbans: when to go, and when it's closed

The Sundarbans, the world's largest mangrove forest, is not open all year. The Forest Department closes it for three months each monsoon so that fish, wildlife and plants can breed and regenerate undisturbed.

When it's closed

In 2026, entry was banned for everyone, including tourists, fishermen, wood collectors and honey collectors, from 1 June to 31 August. The Forest Department, Coast Guard and River Police monitored the closure jointly. The forest reopened to visitors on 1 September.

When to go

The forest is open from September to May. Most visitors go in the dry, cooler months from November to February, when river travel is most comfortable. That is also peak demand, so book early.

How trips work

• Most trips run as multi-day boat packages from Khulna or Mongla.
• Entry needs Forest Department permission and fees. Registered tour operators usually arrange this; ask when you book.
• Check that the operator is registered, the boat carries life jackets, and the trip includes a trained guide.

In the forest

• Keep noise down and don't play music; wildlife moves away from sound.
• Never throw plastic or waste into the rivers or forest.
• Only leave the boat when your guide says so.
