If you plan diving in Thailand then you should dive Hin Daeng (Red Rock) which is a great Phuket dive site. Hin Daeng is very close to Hin Muang (approx 500 meters apart) consists of walls, plateaus and rocks. A submerged pinnacle, where three rocks just break the surface. This is one of the very few dive sites in Thailand where you can see grey reef sharks. Whale sharks and manta rays are also known to visit this dive spot. Here you might also see leopard sharks, great barracudas, octopus, and plenty of cleaner shrimps. In the north there is a valley with small boulders which are completely jeweled with soft coral. Try and take a look in the cracks and crevices for many species of pipefish found here.
Hin Muang (Purple Rock) is a completely submerged rock. It is very close to Hin Daeng (approx 500 meters apart). Named Purple Rock because of it’s dense covering of soft Purple corals. Even though it is very close to Hin Daeng it is a completely different dive site. It features the deepest drop off in Thai waters. The large rock, approximately 200 meters in length, is covered with soft anemones.There is an incredible amount of marine life to be found here including Ornate Ghost Pipefish, Great Barracudas, and Tuna. Swim off of the rocks to spot the many Manta Rays that can be found here along with the odd Whale Shark – if you are especially lucky!.
