Ko Tae Nai
An artificial coral nursery beside a gentle island reef
Ko Tae Nai is an island 10 minutes south of Thongsala, the pier town where the Samui ferries land on Koh Phangan. Its dive is a gentle, shallow reef on the west side of the island, with an artificial coral nursery as a second point of interest.
Also known as Koh Tae Nai.
Where it is and how deep
9.7107° N, 99.9724° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
Along the west side of the island the reef drops slowly to about 7 m, so the whole dive stays in shallow water. Divers follow this slope along the island, and the site also holds an artificial coral nursery. At times a bit of current runs over the reef.
