About Trincomalee

A natural deep-water harbour cupped by headlands makes Trincomalee a strategic port treasured by empires for 2,400 years—Portuguese, Dutch, British all fought to control it. The Koneshwaram Temple rises on Swami Rock above turquoise water where pilgrims bathe in sacred pools. Coral reefs surround the coves; dolphins glide in the shipping lanes.

Trincomalee, on Sri Lanka's northeast coast, has one of the world's finest natural deep-water harbours and a long history as a strategic port, visible today in its colonial-era fort and the clifftop Koneswaram Temple. Its beaches, particularly nearby Uppuveli and Nilaveli, are quieter and less developed than those on the south coast, with calm waters, snorkelling and diving around Pigeon Island National Park, and whale and dolphin watching trips during the season.

Traveler reviews

★★★★★

Snorkelling around Pigeon Island was fantastic — clear water, reef fish everywhere and even a small reef shark. Nilaveli beach itself is quiet and undeveloped compared to the south coast.

Aravinda S. · July 2023

★★★★☆

Koneswaram Temple on the cliff above the harbour is a striking spot, with great views out to sea. The town itself is low-key but a good base for the beaches nearby.

Heidi M. · August 2024

★★★★☆

Came for the dry season here while the south coast was getting monsoon rain, and it worked out perfectly. Uppuveli beach was relaxed with good seafood restaurants right on the sand.
