Koh Rok
Koh Rok is a pair of islands about 25 km south of Koh Haa, separated by a shallow channel and fringed by white beaches. Diving is mostly easy and shallow, much of it around 5–20 m, on hard-coral slopes on the west and softer coral, gorgonians and sponges on the east, where green and hawksbill turtles feed. Schools of snapper, moray eels, powder-blue surgeonfish and clownfish are typical, and blacktip reef sharks are seen early and late in the day. The southern point can pick up current and is then dived as a drift.
depth: 3–25 m
