Basic Information

About This Park

Gulf of Mannar Marine National Park protects 21 islands and surrounding marine habitats along the Tamil Nadu coast. The larger biosphere reserve is known for coral reefs, seagrass beds, mangroves, seaweeds, dugong habitat, reef fish, and coastal birds. Tourism access to the protected islands is regulated, so visitors usually experience the region through interpretation centers, coastal viewpoints, approved boat routes, and nearby beaches rather than free island landing.
