The Sundarbans form the largest contiguous mangrove forest on the planet, stretching across roughly 10,000 square kilometres where the Ganges, Brahmaputra, and Meghna rivers empty into the Bay of Bengal. What many first-time visitors overlook is that this UNESCO World Heritage Site is not a single destination — it is divided by an international border. About 40 % of the forest lies in India (West Bengal) and the remaining 60 % in Bangladesh (Khulna Division). If you have been searching for whether Sundarban India or Bangladesh is the better side to visit, this guide breaks down the key differences in area, wildlife, permits, and overall tourist experience so you can plan the right trip.
Area, Geography, and UNESCO Status
The Indian Sundarbans cover approximately 4,263 square kilometres, of which 2,585 square kilometres form the Sundarban Tiger Reserve and the core national park. The Bangladesh Sundarbans are significantly larger at roughly 6,017 square kilometres, making up the bigger portion of the delta. Both sides earned independent UNESCO World Heritage Site designations — India in 1987 and Bangladesh in 1997. The terrain on each side is similar: tidal waterways, mudflats, and dense mangrove islands. However, the Indian side tends to have narrower creeks and more human settlement along its fringes, while the Bangladesh side retains larger tracts of unbroken wilderness.

India vs Bangladesh — Side-by-Side Comparison
| Parameter | Indian Sundarbans | Bangladesh Sundarbans |
|---|---|---|
| Total Area | ~4,263 km² | ~6,017 km² |
| Tiger Population (est.) | ~100 (2024 census) | ~114 (2024 census) |
| UNESCO Status | Since 1987 | Since 1997 |
| Entry Point | Godkhali / Canning (from Kolkata) | Mongla / Khulna |
| Permit Required | Yes — Indian nationals & foreigners | Yes — via Forest Department, Khulna |
| Permit Cost (approx.) | ₹100–₹400 per day | BDT 1,500–3,000 per day for foreigners |
| Best Season | October – March | November – February |
| Safari Style | Motorised boats + watchtowers | Larger launches + forest trails |
| Tourism Infrastructure | Well-developed; eco-resorts, homestays | Basic to moderate; growing steadily |
| Ease of Access for Indians | High — no visa needed | Low — Bangladesh visa + local permits |
Tiger Population and Wildlife Sightings
The Royal Bengal Tiger is the headline act on both sides, yet sighting odds differ. India reported roughly 100 tigers in the latest census, concentrated in a smaller core zone. Watchtower observation at Sajnekhali, Sudhanyakhali, and Dobanki provides fixed vantage points, while boat safaris follow mapped tiger corridors. Bangladesh holds around 114 tigers spread over a much wider area, which can make individual sightings rarer despite the higher count. Both sides host estuarine crocodiles, Gangetic dolphins, fishing cats, and over 300 bird species. Explore more in our Sundarban facts and amazing things article.
Permits, Access, and Tourist Infrastructure
For Indian tourists, the domestic Sundarbans win on convenience. A day trip starts just 100 kilometres from Kolkata with entry permits available online or at Gosaba check-posts. Foreign nationals need a valid Indian visa plus a forest entry permit, both of which are straightforward. The Bangladesh Sundarbans require a visa (for Indian and most international travellers), a separate forest permit from the Divisional Forest Office in Khulna, and a licensed local tour operator. Infrastructure on the Indian side has matured considerably — eco-resorts, budget homestays, and organised Sundarban tour packages cater to every budget. On the Bangladesh side, accommodation ranges from government rest houses to a growing handful of private eco-lodges, though facilities outside Khulna remain basic.
Which Side Should You Choose?
If you want a hassle-free mangrove safari with comfortable stays and well-mapped boat routes, the Indian Sundarbans are the practical choice. Proximity to Kolkata, familiar currency, and an established tour-operator network make planning effortless. Adventurous travellers holding a Bangladesh visa who crave wilder, less-crowded forest will find the Bangladesh side rewarding — expect longer boat journeys, fewer tourists, and a raw wilderness feel. Either way, the mangrove ecosystem is contiguous; tigers, dolphins, and tidal rhythms do not recognise the border. Sundarban Ecofriends organises guided trips on the Indian side with transparent pricing, solar-powered boats, and community lodges. Share your dates on WhatsApp for a custom itinerary.
Frequently Asked Questions
Is Sundarban in India or Bangladesh?
Sundarban spans both countries. About 40 % of the mangrove forest (4,263 km²) lies in West Bengal, India, and the remaining 60 % (6,017 km²) is in the Khulna Division of Bangladesh. Both sides hold independent UNESCO World Heritage Site status.
Which side of Sundarban has more tigers?
Bangladesh holds a slightly higher estimated tiger population (~114) compared to India (~100). However, because the Indian core zone is smaller and has fixed watchtowers, tiger sighting chances per visit are often comparable.
Do I need a passport to visit Bangladesh Sundarbans from India?
Yes. Indian citizens need a valid passport and a Bangladesh visa. You also need a separate forest entry permit from the Divisional Forest Office in Khulna. No passport is required for the Indian Sundarbans if you are an Indian national.
Which Sundarban side is easier to visit for Indian tourists?
The Indian Sundarbans are far more accessible. The entry point at Godkhali is only about 100 km from Kolkata, permits are available online, and a wide range of tour packages, eco-resorts, and homestays are readily available.
Can I visit both Indian and Bangladesh Sundarbans in one trip?
It is not possible to cross the border inside the forest. You would need to return to Kolkata, fly or travel overland to Khulna in Bangladesh, and arrange a separate tour. Most travellers plan them as two independent trips.
