Sea Frog - Similan Islands

Sea Frog runs daily trips out of the Similan Islands, focusing on relaxed diving at some of the best granite boulder sites. We find they’re a good pick for divers who want to maximise bottom time and minimise fuss, often hitting multiple sites like Christmas Point and Deep Six in a single outing. It’s a no-frills setup for folks keen on the diving itself, not the resort experience. Their small boat means less crowding, a definite plus when the main sites get busy.
