The Gulf of Mannar Marine National Park protects one of South Asia’s richest marine ecosystems. Encompassing coral reefs, seagrass beds and mangrove swamps, it sustains an extraordinary array of life. Dugongs, sometimes called “sea cows,” graze in the seagrass meadows, while dolphins dance in pods across turquoise waters. Green turtles nest on its sandy beaches, while reef fish shimmer like living jewels within coral gardens.  

The park also forms part of a crucial migratory route for seabirds, linking marine and terrestrial ecosystems. Offshore islands dot the seascape, each harbouring unique habitats. Its mangroves provide nurseries for fish and crustaceans, highlighting the interconnectedness of land and sea. 

For travellers, the Gulf of Mannar offers immersive marine experiences. Responsible snorkelling and diving reveal intricate coral structures alive with parrotfish, clownfish and rays. Encounters with dugongs remain rare and magical, while dolphin sightings are more common. 

As Sri Lanka’s only marine national park, it underscores the importance of ocean conservation. Efforts to protect its fragile ecosystems continue, ensuring that future generations can witness this underwater wilderness. Visiting here is more than an adventure, it is a chance to connect with the living pulse of the Indian Ocean.
