Hin Muang is an exciting dive, and it is the highest vertical reef wall in Thailand. The rock formation is completely submerged and has an amazing amount of marine life. The name of the dive site comes from the large amounts of purple soft corals found here and Hin Muang translated from Thai means Purple Rock.
The wall is said to look like a huge loaf of bread; or a loaf of bread that is 200 metres by 20 metres. The southern side is the deeper side and drops down with a sheer drop to about 60 metres. The eastern side has a slower descent and also goes down into the blue depths. Divers should always keep an eye on their depths as it can be easy to drop down to very deep levels.
There are large amounts of purple soft corals all over the wall but the walls are also decorated with huge sea fans in different colours. They are mainly orange, white, and red and they are covered in large schools of glassfish that hide between the fans. Passing trevallies often try their luck at grabbing one or two of these smaller fish. The shallower sections of the wall are covered in anemones and they are filled with anemone fish and clown fish. They are also brimming with macro life and photographers will not run out of subjects amongst this reef.
The big stars are the larger pelagic fish that patrols the wall. Grey reef sharks and leopard sharks are commonly spotted.
