Hin Muang (Purple Rock) is a completely submerged rock. It is very close to Hin Daeng (approx 500 meters apart). Named Purple Rock because its dense covering of soft Purple corals. Even though it is very close to Hin Daeng, it is a completly different dive site. It features the deepest drop off in Thai waters.
The large rock approximately 200 metres in length is covered with soft anemones, which look like fields. There is an incredibale amount of marine life to be found here among them are Ornate Ghost Pipefish, Great Barracudas, and Tuna. Try and swim off of the rocks to spot the many Manta Rays that can be found here along with the odd Whale Shark.
