Garang Heng - Similan Islands

Garang Heng, a submerged reef east of Phi Phi Leh, feels like a private escape since it’s generally only visited by day boats from Phi Phi itself. We found it’s a calm, easy dive, with gentle currents carrying you over a mix of hard and soft corals and some impressive barrel sponges. The reef crests at around 6 meters, then drops to 24, making it a comfortable multi-level profile. Keep an eye out for leopard sharks here; they’re regular visitors and definitely a highlight. This site is a solid choice for a relaxed dive, good for newer divers or those looking for a peaceful afternoon.
