Gekko Scuba Divers | Southeast

Overview:
The southernmost island in the Koh Haa group is also the largest (yai = big). It is known for the caves and caverns that riddle the limestone island, among which is a large cavern called “the twin cathedral,” accessible to recreational divers.

Characteristics:
This limestone island has eroded away leaving a sheer cliff on the south side descending nearly vertically into the water to a depth of 18 to 20 meters. At the base of the wall, at about 14 meters, is the entrance to a huge double cavern linked by way of a passage in the wall dividing the two halves.
Highlights:
The marine life here is similar to that of the surrounding islands, so the real draw of this dive site is the twin cavern. Daylight filters into the cavern creating a blue glow. The ceiling is actually above sea level, and it is possible to break the surface to look around at the stalactites hanging down from the top of the hall.
Marcia's notes:
The twin cathedral cavern is large and fully within the light zone, so no cave training is needed to dive it. However other caves in the island do require special training to explore, and therefore recreational divers are warned not to enter them.
