Hin Daeng (Red Rock) and Hin Muang (Purple Rock) are two of the best sites for scuba diving in Thailand. Situated in Mu Koh Lanta National Park about 100 km (62 miles) south of Phuket, these sites are almost impossible to explore fully without taking a liveaboard trip. They are ranked even higher than the famous Similan Islands and Richelieu Rock and are home to some of the most spectacular marine life in the world. 

Because Hin Daeng and Hin Muang dive sites are deeper and prone to currents, this Thailand diving trip is only suitable for experienced divers. With stunning scuba diving throughout the season, divers have a great chance of seeing both whale sharks and manta rays, as well as a colorful array of shoaling fish, pelagic schools, and plenty of macro critters. Although only a short distance away, the diving on offer at Hin Daeng and Hin Muang is different from what you’ll experience on our Similan Islands liveaboard, South Andaman Liveaboard, Koh Lipe Liveaboard, or Myanmar Liveaboard.

The topography of Hin Daeng and Hin Muang is unique. Hin Daeng resembles the tip of an iceberg breaking the surface. The southern side of the reef is covered in red broccoli corals and drops sharply to around 70 meters, whereas the northern slope is more gentle. Hin Muang is a long slender ridge-like reef starting at about 10 meters below the surface and is covered with stunning anemones.  Several peaks descend like giant stepping stones down to around 20-22 meters.  Walls covered with corals plunge 60 meters to the ocean floor.
