Undoubtedly the most famous dive site in the Gulf of Thailand. Located between Koh Phangan and Koh Tao, all the wonders of this exciting site can be explored by all levels of divers. This spectacular rock rises out of the water creating the best wall dive with a maximum depth of 40 meters.

The wall is covered in soft sponges along with many oysters and clams. Many small holes make it a perfect habit for white-eyed and yellowmargin moray eels. Large schools of tuna, jacks, travellies and barracudas are common here on all dives. Sometimes you can even watch the famous triggerfish.

The site is best known for it’s naturally formed “chimney” where you can enter at 18 meters and exit at 8 meters.

Whale sharks are occasional visitors to the site.
