Poseidon Diving Centre - Trincomalee & East Coast

The team at Poseidon Diving Centre in Trincomalee are just good people, plain and simple. We’ve always appreciated their down-to-earth approach and how genuinely excited they get about sharing their local reefs. This isn’t a flashy operation; it’s a solid, reliable dive centre perfect for divers who value experienced guides and a friendly atmosphere over luxury. They’re PADI 5 Star IDC, so if you’re thinking about taking the plunge into becoming an instructor, this is a seriously strong contender, offering a real insight into the Sri Lankan dive industry. We love diving with them out to Swami Rock, especially in the mornings before the wind picks up. The visibility often hits that blissful 20-meter mark, letting you really soak in the ancient temple ruins scattered amongst the corals. Keep an eye out for the resident morays peeking from the crevices; we’ve seen some absolute behemoths there. Another favourite is the wreck of the SS Thistlegorm, though you’ll want calm seas for that journey. The currents can get a bit frisky around the east coast, so listen to their local advice – they’ll know the best window for a comfortable dive. They really shine at making sure everyone, from newly certified divers to seasoned pros, feels well looked after and gets the most out of their time underwater.
