Ko Samui is more renowned for its long sandy beaches and sizzling nightlife than its diving, but there are some enjoyable sites nearby.

Sail Rock is by far and away the most well-known dive site in the Ko Samui area. It is a rock pinnacle shaped like an iceberg which emerges from a sandy seabed at 40m to tower 15m above the surface. It is also a magnet for fish and there are fascinating schools of anemones and pink anemones.

Koh Yippon consists of 50 different islands. The visibility is lower than that of the other sites in the area but the scenery is still beautiful.
