About North Rock/ Lom Fang
North Rock/ Lom Fang is a rocky offshore pinnacle off Koh Rin, with coral-covered outcrops, a calmer lee side, and a more exposed edge that can carry noticeable flow. It works best as a guided boat dive where you circle the formation, keep the rock close for orientation, and pause for reef fish and small critters in the structure.
