Koh Ha Yai, Koh Rok, Hin Daeng and Hin Muang are the principal diving areas furthest south in Thailand literally due west/southwest from Koh Lanta. Hin Daeng and Hin Muang are the more popular sites and rate as certainly two of the best dive sites in Thailand.

Hin Daeng
Hin Daeng is 3m clear of the surface with the southern side dropping to 60m plus. This is the steepest & deepest drop in Thailand's waters. The rock itself is quite barren but offers the opportunity to see large pelagics and fantastic underwater gardens on the shallower shelving eastern side where two ridges descend to 40m plus. Barracuda are a common sighting as well as Fusiliers.

Hin Muang
Hin Muang is only a few hundred meters from Hin Daeng and is completely submerged. The rock, shaped like Ayres Rock (central Australia) is 20m wide and 200m long. It is covered with purple soft corals and anemones, hence it's name (Muang is purple in Thai). Many sea fans of varying colors decorate the steep sides and it has a remarkable amount of life on it compared to its neighbor.

Whalesharks, Sharks and Mantas are regularly seen around the two pinnacles enjoying the freedom that the depth of water here offers them.
