Why dive here
With 173+ marine species recorded in the area - including blacktip reef sharks, eagle rays, giant moray eels, whale sharks and clownfish - Loh Samah Bay offers some of Similan Islands's richest reef diving. Water ranges 29-31°C, warmest April, May, June.
Loh Samah Bay, tucked away on the south side of Phi Phi Leh, feels like a familiar friend after the buzz of Maya Bay. The diving here centers on a small cliff islet at the bay’s entrance. You can easily circle it on a single tank, taking your time to explore the wall that drops to 20m on the outer side and stays shallow, around 8m, on the inner. The whole wall is plastered in corals, both hard and soft, with giant clams tucked into crevices. It's a relaxed dive, good for stretching out a longer bottom time and keeping an eye out for reef sharks cruising the deeper sections.
