About Rainbow Reef
Rainbow Reef is a shallow training reef in the southern part of Sairee Beach, Koh Tao. It is the kind of calm, easy site that works well for a first scuba dive or a relaxed snorkel session, with reef fish close to the beach and an easy-going training profile. It is a useful place to build confidence before moving on to Koh Tao's deeper walls and pinnacles.
