Hin Daeng and Hin Muang Liveaboards – Soft Coral Walls, Thailand
Hin Daeng and Hin Muang are two remote pinnacles south of Koh Lanta, in the southern Andaman Sea of Thailand. Their walls drop deep into the blue and are covered in red and purple soft coral. Mantas and whale sharks pass by in season. It’s a different trip from the Similans, for more experienced divers.
