Phi Phi Leh is defined by its variety of site types packed into a compact island: walls, reefs, caves, caverns, canyons and pinnacles, all reached by boat. The topography suits a wide range of skill levels, from beginner-friendly wall dives at Pileh Wall to the more demanding mixed terrain at Palong Bay. Reef fish are abundant across the island, with Sea Krait, Giant Moray and Yellowtail Clownfish observed regularly. Zebra Shark and Pharaoh Cuttlefish add interest for those willing to look more carefully.
