About Gulf of Mannar Biosphere Reserve

The Gulf of Mannar Biosphere Reserve is a unique marine protected area along the southeastern Indian coast, renowned for its rich biodiversity, coral reefs, and vital habitats supporting rare marine and terrestrial species.

Wilderness Landscape & Natural Heritage

Located between the southeastern tip of India and the west coast of Sri Lanka, the Gulf of Mannar Biosphere Reserve encompasses a rich marine ecosystem with over 21 small islands, coral reefs, seagrass beds, and mangrove forests. Spanning parts of Tamil Nadu and Kerala, this reserve was established in 1989 and is India's first marine biosphere reserve. The area serves as a natural habitat for endangered species such as the dugong (sea cow), various sea turtles, and a diversity of coral and fish species. The reserve’s coral reefs are among the most productive and biologically diverse in the Indian Ocean region. In addition to its rich marine life, the coastal and island ecosystems host unique birdlife and endemic plant species. Historically, the Gulf of Mannar has been important for traditional fishing communities and trade routes connecting India and Sri Lanka. Outdoor and nature enthusiasts can explore the reserve through guided boat tours, snorkeling, and diving at select locations with local permissions. Though access to many islands is regulated to protect sensitive habitats, visitors can observe wildlife, coral formations, and coastal landscapes from boats or the mainland. The area also plays a key role in regional conservation and sustainable fisheries management. Visitor appeal lies in its exceptional biodiversity, opportunities to witness rare marine species, and its relatively untouched natural beauty. Visitor infrastructure is minimal, so preparation and local guides are recommended for safe and responsible access.
