Why dive Trincomalee?

Trincomalee — known locally as Trinco — sits on one of the world's finest natural harbours and delivers diving that rivals any destination in the Indian Ocean. Choose between two distinct regions: Trincomalee & Nilaveli, home to Pigeon Island National Park and iconic sites like Swami Rock and the SS Sagaing wreck; or Pasikudah & Batticaloa, where legendary wrecks like HMS Hermes, the Catalina Plane Wreck and the SS British Sergeant await. Beyond diving, Trinco offers magical dolphin and whale-watching excursions, sunrise and sunset ocean experiences, and historic harbour tours that unlock the secrets of one of Asia's greatest colonial-era ports.
