Hin Daeng & Hin Muang are two world-famous dive sites located in southern Thailand, known by most simply as ‘Hin Daeng.’ The underwater pinnacles are out in the middle of open sea, far from any island or the mainland, and are barely visible at all from above the surface. Because of their size and remote location, they are absolutely perfect for exciting scuba diving experiences, down to challenging depths. The tropically-warm water is crystal clear and the marine life is out of this world. While Hin Daeng & Hin Muang are home to hundreds of species of fish, invertebrates and even marine reptiles, the pinnacles are visited by pelagic species to feed or be cleaned. The most commonly talked about large pelagic fish to visit Hin Daeng & Hin Muang are Manta Rays & Whale Sharks. However, even if divers don’t encounter these two gentle giants, the sites’ topography and the rest of the marine life almost guarantee unforgettable diving experiences.
Hin Daeng & Hin Muang are not dive sites for new or learning scuba divers. The depths, currents, and lack of a beach or shallow reef mean that diving here is really only for experienced divers. This includes Open Water certified divers with more than 25 logged dives, but preferably those who are certified to dive to 30 metres. In fact, it’s possible to exceed 60 metres at Hin Muang, although only for very experienced divers.
Diving in a strong current is very much an acquired taste, and not usually suitable for those who want to enjoy as much time under the surface as possible. Therefore, dives are carefully planned to be at the right time of day and in the best part of each of these huge underwater mountains. Those coming to Hin Daeng & Hin Muang on a day trip, are most likely to come from Koh Phi Phi or Koh Lanta by speedboat, and can enjoy two day dives. Liveaboard cruises are the best way to experience diving at Hin Daeng & Hin Muang, with three day dives starting early in the morning – before the daytrippers arrive. Due to its exposed and remote location in open sea, there is no protection from nearby islands, meaning that the surface can sometimes be choppy, and liveaboard boats do not moor here for the night. Instead, they normally sail to Koh Haa after the third day dive.
