This dive site, Ao Khai on Koh Chan, is situated approximately 40 minutes by boat from Samaesan fishing village. It is an easily accessible and relatively shallow reef that starts at just 3 meters and slopes down to a maximum of 12 meters. Its gentle profile and calm conditions make it ideal for beginners and snorkelers to explore the underwater world with ease.
The site is teeming with marine life throughout the year. Divers and snorkelers can regularly spot beautiful Hawksbill turtles gracefully gliding through the water, as well as blue spotted rays resting on the sandy bottom. Numerous species of puffer fish are also commonly found, adding to the vibrant diversity of the reef.
Ao Khai is a fantastic destination for year-round diving due to its consistent marine activity. It's particularly recommended for those new to diving or freediving due to its shallow depths and calm environment. The site offers great opportunities for underwater photography, especially for wide-angle shots of turtles and rays, and macro opportunities among the reef.
