Why dive here
With 54+ marine species recorded in the area - including sea turtles, tiger sharks and pufferfish - Koh Raet offers some of Koh Tao's richest diving. Water ranges 29-31°C, warmest April, May, June.
Koh Raet, just off Koh Tao, is a pretty chill dive. It’s mostly sand and small coral bommies, which means you’ll often spot stingrays, gobies, and maybe even a pipefish or two in the quieter spots. We think it's a good choice for newer divers or those looking for a relaxed second dive, easygoing and generally calm.
