First dive of the day, the descent is along a rope and then drift with the current from east to west (or vice versa) along one of the two faces of the reef. The walls are decorated with wide sea fans and sea whips while anemone fields and purple soft corals adorn the top of the reef. The good visibility and the currents facilitate the meeting with pelagic species that may happened any time like the blue whale shark, the manta rays and the schools of tuna. The leopard sharks, the reef sharks, the hawksbill turtles, the jackfishes, the rays , the tunas, the wahoos, the schools of fusiliers and barracudas, many varieties of reef fish are moving on and around the reef.

Hin Daeng or the Red Rock

As Hin Muang, Hin Daeng is covered with anemones and with red soft corals which gave it its name. Hin Daeng is a huge rock formation, submerged up to 40 meters and with three pinnacles emerging above the surface. The eastern and northern parts of the reef are shallower than those to the west and south which sink of advantage towards the bottom over the normal recreational diving limits.
