Sundarbans National Park — A Complete Travel Guide to India’s Mangrove Wonderland

The Sundarbans National Park, located in the southern part of West Bengal, is one of India’s most awe-inspiring natural wonders. Spanning a vast network of tidal waterways, mudflats, and dense mangrove forests, it forms part of the world’s largest delta created by the Ganga, Brahmaputra, and Meghna rivers. Recognised as a UNESCO World Heritage Site, this unique ecosystem is home to an extraordinary variety of wildlife — from the elusive Royal Bengal Tiger to estuarine crocodiles, spotted deer, and hundreds of bird species.

What makes the Sundarbans truly exceptional is its constantly changing landscape, where land and sea blend seamlessly with the rhythm of tides. This enchanting wilderness offers an unforgettable experience for travellers seeking raw natural beauty, adventure, and peace. Beyond its ecological value, the Sundarbans also support the livelihoods of local communities who coexist with the forest’s untamed character. Visiting this mangrove paradise is not just a journey through nature, but a lesson in harmony and resilience — where every tide tells a story of survival.

1. History and Geography

The history of the Sundarbans National Park is deeply rooted in India’s conservation legacy and the evolution of its rich deltaic landscape. The name “Sundarbans” is derived from the Sundari tree (Heritiera fomes), one of the dominant mangrove species found here. Initially, parts of this region were declared as the Sundarbans Tiger Reserve in 1973 under Project Tiger, and later, in 1984, it was designated as a National Park to enhance wildlife protection and preserve the mangrove ecosystem.

Geographically, the park lies at the confluence of three great rivers — the Ganga, Brahmaputra, and Meghna — which together form the world’s largest delta. It covers an area of about 1,330 sq km, forming the core zone of the larger Sundarbans Biosphere Reserve, which extends over 9,600 sq km. The terrain is a complex mosaic of tidal waterways, mudflats, creeks, and islands, many of which submerge and reappear with the changing tides.

This dynamic landscape supports both terrestrial and aquatic life, creating a fragile yet fascinating ecosystem that constantly adapts to nature’s rhythm. The geography of the Sundarbans not only shapes its biodiversity but also defines its identity as a living, breathing delta.

2. Flora and Fauna of Sundarbans

The Sundarbans National Park is a living testament to nature’s resilience and diversity. As the world’s largest mangrove ecosystem, it supports an incredible range of life forms uniquely adapted to its saline, tidal environment. The constant ebb and flow of seawater have created a habitat unlike any other — one that blends terrestrial and aquatic life in perfect balance.

2.1 Flora

The park’s vegetation is dominated by mangrove forests, consisting of salt-tolerant species that thrive in muddy, oxygen-poor soils. These trees have stilt roots and pneumatophores (breathing roots) that help them survive tidal submersion. Prominent mangrove species include:

• Sundari (Heritiera fomes): The tree after which the region is named, known for its durable timber.
• Gewa (Excoecaria agallocha): A common mangrove species found along creeks.
• Goran (Ceriops decandra) and Keora (Sonneratia apetala): Important stabilisers of muddy banks.
• Dhundul (Xylocarpus granatum) and Passur (Xylocarpus mekongensis): Trees with large, decorative fruit and medicinal value.

These mangroves not only protect the coastline from erosion and cyclones but also serve as nurseries for fish and crustaceans, making them vital to local livelihoods.

2.2 Fauna

Sundarbans is most famous as the domain of the Royal Bengal Tiger, a population uniquely adapted to swim across tidal creeks and hunt in saline conditions. Besides tigers, the park shelters a rich array of wildlife:

• Mammals: Spotted deer, wild boar, fishing cat, and rhesus macaque.
• Reptiles: Saltwater crocodile, monitor lizard, king cobra, and olive ridley turtle.
• Aquatic life: Mudskippers, crabs, prawns, and diverse fish species.
• Birds: Over 250 species, including black-capped kingfisher, white-bellied sea eagle, herons, egrets, and migratory ducks.

Together, these species form an intricate food web sustained by the tides. The Sundarbans’ biodiversity isn’t just about wildlife—it’s a delicate symphony of land, water, and life that thrives against the odds, making it one of Earth’s most extraordinary ecosystems.

3. UNESCO World Heritage Site Status

In 1987, Sundarbans National Park was recognised as a UNESCO World Heritage Site, highlighting its global ecological significance and the urgent need for its protection. This designation underscores the park’s value as one of the world’s largest mangrove forests, a habitat that supports a rare combination of terrestrial and aquatic species, including the iconic Royal Bengal Tiger.

The UNESCO recognition was based on several key factors:

• Unique ecosystem: The Sundarbans is the only mangrove forest of its size where tigers have adapted to a saline and tidal environment.
• Biodiversity hotspot: It houses an extensive variety of flora and fauna, many of which are endangered or endemic to the region.
• Natural processes: The park represents a dynamic deltaic environment shaped by the interplay of rivers, tides, and sediment deposition, which is of significant scientific interest.

Being a World Heritage Site has also brought international attention and resources for conservation efforts, enabling programs to protect the delicate mangroves, monitor wildlife populations, and promote sustainable eco-tourism. Today, Sundarbans stands not only as a symbol of natural beauty but also as a beacon for global environmental preservation, emphasising the importance of balancing human presence with the survival of one of Earth’s most extraordinary ecosystems.

4. Safari Experience in Sundarbans National Park

Exploring Sundarbans National Park is best experienced through its iconic boat safaris, which allow visitors to navigate the labyrinth of creeks, rivers, and tidal channels. These safaris provide a unique perspective of the mangrove ecosystem, where every turn may reveal fascinating wildlife and the interplay of land and water.

4.1 Types of Safaris

Most safaris are guided boat tours arranged by forest authorities or licensed eco-tour operators. The boats vary from traditional wooden vessels to motorised launches, designed to safely traverse the shallow channels.
