The highlight of diving here is cave diving with a series of underwater caves, the largest cavern of the islands is located in Koh Ha Yai. The caves are safe to enter, as the entrances are large and there is only one way in and one way out. The best part of entering these caves is that you can ascend to the surface inside heart of island. Scenic of stalactites hanged from the top of the ceiling over 30 meters high, and the light filtering through the water from the entrance is the touch of the divine. We advise to take torches to this dive site.
Besides the cavern, Whale sharks may be seen into the blue...
