All 4 Dive - Similan Islands

All 4 Dive operates out of the Similan Islands, putting them right on the doorstep of some fantastic dive sites. They focus on liveaboard trips, which makes sense given the Similans are best explored over a few days. If you’re looking to maximise your dive time with early morning and late afternoon dives, a liveaboard with them is a solid choice. This setup really suits divers who want a comprehensive tour of the area without the daily boat commute from the mainland.
