About Gahirmatha Marine Wildlife Sanctuary

Gahirmatha Marine Wildlife Sanctuary is a protected marine and coastal estuarine ecosystem in Rajnagar Forest Division of Kendrapara district, Odisha. It is internationally known for the mass nesting of Olive Ridley sea turtles (*Lepidochelys olivacea*) and is recognised as the world's largest known Olive Ridley mass-nesting rookery.

The sanctuary lies beside the Bhitarkanika National Park landscape, where mangrove estuaries meet the Bay of Bengal. Its shifting sandy barriers, mudflats, dunes and nearshore waters provide important habitat for Olive Ridley turtles and other marine and estuarine wildlife.

Gahirmatha was formally declared a marine wildlife sanctuary by the Government of Odisha on 26 September 1997. The protected area covers 1,435 sq km, comprising a 735 sq km core marine zone and a 700 sq km buffer zone.

The area is not a conventional beach destination. Visitor access is strictly controlled, and general tourists cannot walk onto the core turtle nesting beaches. The primary visitor experience is a permitted boat excursion through the marine and estuarine environment.

Key Attractions & Things to See

Olive Ridley Mass Nesting

The defining attraction of Gahirmatha is the annual mass nesting of Olive Ridley sea turtles. During an arribada, large numbers of female turtles come ashore together to lay their eggs on sandy coastal stretches.

The nesting phenomenon was scientifically identified at Gahirmatha in 1974. Offshore turtle aggregations can also occur before the nesting period as turtles gather in shallow coastal waters.

Nasi Islands

Nasi-1 and Nasi-2 are dynamic, uninhabited sandy islands associated with the sanctuary's turtle nesting ecosystem. These shifting coastal formations are shaped by deltaic and marine processes.

Direct tourist foot access to the core nesting beaches is prohibited to protect nesting turtles and their egg pits.

Coastal Estuarine Landscape

Gahirmatha contains a combination of sandy islands, mudflats, dunes, mangrove estuaries and shallow coastal waters. The sanctuary extends around the marine environment between the Dhamra River mouth in the north and the Brahmani River mouth in the south.

Marine and Estuarine Wildlife

The sanctuary supports Olive Ridley sea turtles, saltwater crocodiles, white-bellied sea eagles, horseshoe crabs and marine dolphins.

Irrawaddy dolphins and Indo-Pacific humpback dolphins may also be associated with the river-mouth and coastal waters.

Mangrove Vegetation

Mangrove species found in the ecosystem include Avicennia marina, Rhizophora mucronata and Sonneratia apetala. Coastal creepers and other shoreline vegetation are also part of the habitat.

Turtle Conservation Infrastructure

The protected landscape contains forest department anti-poaching camps, turtle monitoring facilities, hatcheries and watch towers. These facilities support monitoring and protection rather than conventional tourism.

Popular Activities & Things to Do

Take a Permitted Boat Safari

The main visitor activity at Gahirmatha is a Forest Department-authorised boat excursion. Boats travel from designated access points such as Khola or Gupti through the Bhitarkanika river channels towards the marine mouth.

Observe Turtle Nesting Ecology

Visitors can experience the coastal environment and, during the appropriate season, observe turtle-related activity from permitted boat excursions. Direct access to nesting beaches is prohibited for general tourists.

Explore the Estuarine Landscape

The boat journey provides an opportunity to experience tidal channels, mangrove surroundings, sandy coastal formations and the transition between the Bhitarkanika estuarine system and the Bay of Bengal.

Observe Coastal Wildlife

The sanctuary's protected waters and estuaries provide opportunities for wildlife observation, including sea turtles, dolphins, saltwater crocodiles and coastal birds.
