Hin Muang

Located just a short distance from its sister site Hin Daeng, Hin Muang (or “Purple Rock”) is a legendary dive site in southern Thailand and a staple on high-end Thailand liveaboard diving itineraries. Famous for having Thailand’s deepest vertical drop, Hin Muang boasts an underwater ridge that descends past 60 meters, cloaked in purple soft corals that shimmer in the current.

This long, narrow pinnacle stretches underwater like a submerged mountain range, offering a dramatic seascape full of life. Divers drift along steep walls and sloping ridges, where pelagics patrol the blue and macro treasures hide in the cracks. With limited surface visibility, Hin Muang is not visible from above—but beneath the waves, it reveals a wonderland of marine biodiversity.

Key marine life highlights include:

• Oceanic manta rays, often gliding in from nearby Hin Daeng

• Whale sharks spotted occasionally during the peak season (Feb–Apr)

• Dense clouds of fusiliers, glassfish, and snapper

• Giant trevally, barracuda, and bluefin tuna on the hunt

• Macro sightings such as zebra morays, shrimp gobies, nudibranchs, and ghost pipefish

Currents at Hin Muang can be swift, making it ideal for drift diving and more suited to intermediate to advanced divers. That said, the rewards are immense—every dive offers the potential for big animal encounters and stunning scenery, all in near-pristine conditions due to the site's remote location.

Hin Muang is accessible only via Thailand liveaboard diving, making it one of the least crowded but most rewarding dive spots in the region.
