Hin Tai Nam is a Koh Chang twin-pinnacle reef with a shallow coral top, a narrow canyon between the pinnacles, and enough structure to keep the dive interesting on every pass. Divers come here for turtles, schooling fish, and the relaxed route options that make the site work for newer divers and repeat fun dives alike. It is a boat dive that rewards an easy pace, good buoyancy, and a willingness to circle the rock instead of rushing through it.
