What to expect underwater
On the east coast, Laem Thian is one of Koh Tao’s most adventurous spots, known for its tunnels, arches, and swim-throughs.
You’ll dive between tunnels and arches as light filters through the rock. Around the reef, you’ll spot bannerfish, batfish, and rabbitfish, with stingrays in the sand and flatworms and shrimps hiding in rubble.
With so much to explore, Laem Thian always feels like a dive with something new to offer.
