Koh Bon Dive Site — Thailand

About Koh Bon

A submerged ridge south of the Similan Islands famous for reliable manta ray encounters from November to April. The western wall drops dramatically from 10 to 40 meters, covered in sea fans and gorgonians that sway in the current. The cleaning station on the ridge attracts mantas that hover motionless while cleaner wrasses work, providing unforgettable close encounters.
