About Trincomalee

Trincomalee is one of Sri Lanka’s most distinctive east-coast destinations, combining a vast natural harbour, tropical beaches, Hindu and Buddhist heritage, colonial fortifications and access to protected marine environments.

The destination is home to the beaches of Nilaveli and Uppuveli, the offshore Pigeon Island National Park, historic Fort Frederick and Koneswaram Temple on Swami Rock. The surrounding coastline also supports seasonal whale watching, diving, snorkelling, fishing communities and quieter beach stays.

Use reef-conscious sun protection where appropriate and avoid leaving plastic or other waste on beaches and islands.

Check wind, waves, currents and visibility before swimming, snorkelling or diving.

Marine activities can be cancelled because of rough seas, rain, poor visibility or operational restrictions.

Whales and dolphins are wild animals, so sightings are never guaranteed.

Carry sun protection and sufficient drinking water during beach and boat activities.
