Why dive here
With 173+ marine species recorded in the area - including blacktip reef sharks, eagle rays, giant moray eels, whale sharks and clownfish - Sa Kaeo Cave offers some of Similan Islands's richest cave diving. Water ranges 29-31°C, warmest April, May, June.
Sa Kaeo Cave in the Similans isn't for the casual diver. This is an expert dive, dropping to 30 metres inside a cavern that demands good buoyancy and comfort in overhead environments. We’ve found the entry can sometimes feel a bit tight, but once inside, the space opens up, giving you room to appreciate the rock formations. Keep an eye out for the small schools of sweepers that often hang near the entrance, catching the shafts of light. It’s a rewarding dive for those with the right training, offering a different vibe from the usual Similan reef dives.
