Diving in Sri Lanka

Why dive with us in Unawatuna

Unawatuna is one of the best places in Sri Lanka to learn to dive and to explore the south coast. Warm water, coral reefs and historic shipwrecks sit minutes from the beach, so you spend your time underwater rather than travelling.

Submarine Diving Center has trained and guided divers since 1991, and has welcomed more than 20,000 guests. As a PADI 5 Star Dive Resort we offer everything from a first guided dive to professional-level courses, with all equipment included and small groups so you get real attention from your instructor.

Complete beginners can try Discover Scuba Diving. Ready to certify? Start the PADI Open Water Diver course. Already certified? Join us for fun dives on wrecks, reefs and night dives, or read our guide to scuba diving in Sri Lanka to plan your trip.
