Hin Muang (Purple Rock)
Hin Muang, located just a few hundred meters from Hin Daeng, lies completely submerged. The rock was the incredible amount of marine life that clung to the rock.
The name derives itself from the thick purple growth of soft corals that are everywhere.
The rock itself is approximately 200 meters long and less than 20 meters wide, and is shaped like a loaf of bread with steep, vertical sides and a rounded top. The walls are decorated with large sea fans of red, white and orange. Clouds of glass fish, or silver sides, school around the fans and rocky outcroppings. Carpets of anemones cover the shallower sections of the pinnacle.
Whalesharks are one animal that we see repeatedly around these pinnacles.
