The Sundarbans is the great tidal mangrove forest at the mouth of the Ganga, and you see it from a boat, not a jeep.
To enter the forest you need an entry permit, and the West Bengal Forest Department issues it. Most travellers do not queue for the permit themselves. They join a boat run by a registered operator, and the operator takes the permit for the whole group. Foreign visitors need extra permission, so plan ahead. You can look at the official Sundarban Tiger Reserve site, sundarbantigerreserve.org, for the rules and the boat booking.
Who needs a permit
Everyone who enters the tiger reserve needs an entry permit, Indian or foreign. You cannot take a private boat into the core without a permit and a registered guide. Because the forest is a maze of tidal creeks, a licensed boat, a boatman and a forest guide go with every trip.
How the permit works, in plain words
The West Bengal Forest Department controls entry to the Sundarban Tiger Reserve. You get a permit for the boat and the people on it, and you show it at the check post, usually at Sajnekhali, where the reserve has its office and a watchtower. In practice, the boat operator arranges the permit for the group, because they know the paperwork and the check posts. You can also see the rules and the boat booking on the official reserve site.
The boat safari, in plain words
Your day is spent cruising the wide channels, stopping at watchtowers such as Sajnekhali, Sudhanyakhali and Dobanki, where you climb up and watch the mudflats and the water. You may see a saltwater crocodile, spotted deer, wild boar, plenty of birds, and, if you are very lucky, a tiger swimming or on the bank. Tiger sightings are rare here, so come for the wild beauty of the mangroves, and treat any tiger as a gift.
For foreign visitors
Foreign visitors need extra permission to enter the Sundarban Tiger Reserve, on top of the ordinary entry permit. A registered operator usually arranges this for you, because it needs the right forms and time. So if you hold a foreign passport, book through a recognised Sundarbans operator well ahead, and carry your passport. [The exact foreigner rule can change, so confirm it with the operator and the forest department before you travel. Last checked 13 September 2026.]
How to book, step by step
Pick a registered Sundarbans boat operator, or use the boat booking on the official reserve site. Tell them your dates and the number of travellers. Let the operator take your entry permit and, if you are a foreigner, the extra permission. Reach the jetty on time, because the boats work with the tide. Carry the same original identity you gave for the permit, because staff check it at the reserve office.
What it costs
Your cost has several parts: the entry permit and camera fee, the boat hire, the guide, and, on most trips, food and a night stay on the boat or at a lodge. The forest department sets the permit and camera fees, and the operator sets the boat and package price. We do not print a fee we cannot see clearly on the official source, because these figures change. You will get a clear price from the operator before you pay.
Documents you need
You need one government photo identity per traveller for the permit. Indians can use Aadhaar. Foreigners use a passport, and need the extra permission. Carry the same original to the reserve office, because staff match it to the permit.
Season, so you plan the right months
You get the best of the Sundarbans in the cooler, drier months, from about October to March, when the weather is kind and the birds are many. The summer is hot and humid, and the monsoon brings heavy rain and high water. Plan for the winter window for the most comfortable trip.
Common mistakes to avoid
- The biggest trap is thinking you can simply drive up and enter, because you cannot; you need a permit and a registered boat. Foreign visitors often forget the extra permission, so arrange it early. Do not expect a guaranteed tiger, because sightings are rare in this vast forest. Do not book a boat that is not registered for the reserve, because it will be turned back at the check post.
