Why dive here
With 173+ marine species recorded in the area - including blacktip reef sharks, eagle rays, giant moray eels, whale sharks and clownfish - Koh Hah offers some of Similan Islands's richest diving. Water ranges 29-31°C, warmest April, May, June.
Koh Hah, nestled within the Similan Islands, offers a relaxed diving experience. We often find good chances to spot leopard sharks resting on the sandy bottom, along with schools of fusiliers around the deeper pinnacles. It’s a site that works well for newer divers or those looking for a gentler drift, with generally mild currents. The rock formations create some interesting swim-throughs, adding a bit of exploration to the dive.
