About Lighthouse Bay
Lighthouse Bay is a tranquil dive site on Koh Tao's northeast coast, named for the navigation light above. The gentle reef slope features scattered bommies with anemone colonies, pipefish hiding in the rubble, and plenty of moray eels peering from crevices. It rarely gets crowded, making it a peaceful alternative to busier west coast sites.
