The Sundarbans is the largest mangrove forest on Earth, and it doesn’t belong to just one nation. Roughly 40 % lies in India (West Bengal) and 60 % in Bangladesh (Khulna Division). Travellers planning a Sundarban India vs Bangladesh trip inevitably ask: which side should I visit? This guide compares area, wildlife, accessibility, permits, cost, and tourist infrastructure so you can make an informed choice.
Size & Geography at a Glance
India’s Sundarban covers about 4,264 km² while Bangladesh’s portion stretches across roughly 6,017 km². The Bangladesh side includes three wildlife sanctuaries — Sundarban West, Sundarban South, and Sundarban East — that together form a UNESCO World Heritage Site inscribed in 1997. India’s Sundarban National Park, also a UNESCO site since 1987, protects 1,330 km² of core tiger habitat within the larger Sundarban Biosphere Reserve.
Both sides share the same tidal river network, mudflats, and dense mangrove ecosystem that make this delta unique. The India–Bangladesh border runs along the Hariabhanga and Raimangal rivers, splitting habitats that tigers, crocodiles, and dolphins cross freely. Ecologically they are one forest; administratively, the visitor experience on each side is quite different.
India vs Bangladesh Sundarban — Detailed Comparison

| Nearest City | Kolkata (≈ 110 km) | Khulna (≈ 50 km) |
| Permit Required | Yes — forest entry + boat | Yes — forest pass via Divisional Forest Office |
| Permit Cost | ₹200–₹400 per person | BDT 1,500–3,000 per person |
| Best Season | October – March | November – February |
| Tourist Infrastructure | Good — lodges, resorts, guided tours | Basic — limited accommodation |

Wildlife & Tiger-Spotting Chances
Both sides harbour the iconic Royal Bengal Tiger, saltwater crocodiles, Gangetic dolphins, horseshoe crabs, and over 300 bird species including kingfishers, white-bellied sea eagles, and masked finfoots. However, tiger-sighting probability differs significantly. India’s watchtowers at Sajnekhali, Sudhanyakhali, and Dobanki funnel visitors along known tiger corridors, improving odds considerably. Guides on the Indian side use pug-mark tracking and camera-trap data to position boats for the best chances.
Bangladesh’s remoter creeks in the East Wildlife Sanctuary offer a wilder, less-managed experience — but sightings are rarer because tourist routes are fewer and watchtowers almost non-existent. If a tiger sighting tops your list, the Indian side has a clear edge thanks to better infrastructure and established permit routes.
Accessibility & Travel Logistics
Getting to the Indian Sundarbans is straightforward. Fly into Kolkata, then drive 3–4 hours to Godkhali or Sonakhali jetty where boats depart daily. Dozens of licensed tour operators run Sundarban tour packages ranging from budget day-trips to premium 3-night houseboat cruises. International visitors only need a standard Indian e-Visa.
Reaching the Bangladesh Sundarbans requires flying into Dhaka, then a domestic flight or 8-hour bus ride to Khulna, followed by a boat to Mongla. Tour operators are fewer, and foreigners need a separate Bangladesh visa plus a forest permit from the Divisional Forest Office in Khulna. The logistics aren’t impossible, but they add a layer of planning that India’s side doesn’t demand.
Cost Comparison
A 2-night package on the Indian side typically costs ₹4,500–₹12,000 per person (≈ $55–$145), covering transport from Kolkata, meals, boat safari, accommodation, and all permits and entry fees. On the Bangladesh side, comparable trips run BDT 8,000–18,000 (≈ $70–$160), though options are fewer and bargaining harder for international tourists.
Factoring in international flights, the Indian side is usually more cost-effective because Kolkata is a major aviation hub with competitive fares from the Middle East, Southeast Asia, and Europe. Budget travellers on the India side can even opt for a single-day boat safari starting at ₹2,500, an option that barely exists in Bangladesh.
So, Which Side Should You Visit?
Choose India if you want hassle-free permits, well-developed tourism infrastructure, easier tiger-spotting odds, and a wide range of tour packages at competitive prices. It’s especially suited for families, first-time visitors, and anyone short on time. Choose Bangladesh if you’re an adventurous traveller seeking raw wilderness, fewer crowds, and the thrill of exploring a less-commercialised forest where every creek feels like a discovery. Many wildlife enthusiasts eventually visit both sides — and that’s the best answer of all.
Frequently Asked Questions
Is the Sundarban bigger in India or Bangladesh?
Bangladesh holds roughly 60 % of the Sundarbans (~6,017 km²), while India’s share is about 4,264 km². However, both sides are UNESCO World Heritage Sites with protected core zones.
Can I visit both Indian and Bangladeshi Sundarbans in one trip?
Not easily. You need separate visas and permits for each country. Most travellers plan two independent trips — one from Kolkata (India) and another from Khulna (Bangladesh).
Which side has more Royal Bengal Tigers?
Bangladesh is estimated to have slightly more tigers (~115 vs ~100), but the Indian side offers better sighting infrastructure with dedicated watchtowers and managed boat corridors.
Do I need a permit to enter the Sundarbans?
Yes, on both sides. In India you need a forest entry permit and a boat permit, obtainable through your tour operator or online. In Bangladesh you must get a forest pass from the Divisional Forest Office in Khulna.
What is the best time to visit the Sundarbans?
October to March is ideal for the Indian side; November to February works best for Bangladesh. These months offer cooler weather, calmer tides, and the highest wildlife activity.
