About Laem Thian
Laem Thian is a rugged rocky point on Koh Tao's east coast where massive boulders have tumbled into the sea, creating an exciting network of small caves, swim-throughs, and overhangs. The deeper sections have caverns where blue-spotted stingrays rest on the sandy floor, and the walls are decorated with colorful sponges and nudibranchs.
Tips
A torch is essential. Check conditions — the east coast is exposed to certain wind directions.
