What to expect underwater
Around 30 minutes north of Chalok Bay, Green Rock is a playground of swim-throughs, arches, and caves.
Schools of snapper, angelfish, and butterflyfish circle the reef, while stingrays and moray eels hide in the sand and crevices.
It’s one of the best dive sites on Koh Tao to explore while sharpening your buoyancy and navigation skills.
