Koh Bon West Ridge

Koh Bon's western ridge is Thailand's most reliable manta station. The limestone spur steps down from the island to a nose at around 18-25 m where cleaning stations operate, and reef mantas arrive on their own schedule to bank in slow circles overhead, sometimes one, sometimes a squadron that stays the whole dive. Etiquette is drilled: hold the reef side, stay low, let the animals run the geometry. Manta-less days still pay in yellow soft coral on the ridge's north face, octopus in the rubble, and napoleon wrasse cruising the steps. Liveaboards revisit until the mantas oblige.

Momen yang Anda nantikan: Reef mantas at cleaning stations, a diveable ridge line in all currents, repeat-visit rhythm

Topografi: Limestone ridge stepping down to a deep point

Arus: The ridge nose catches flow from both sides; mantas prefer it that way.

Bahaya: Current at the nose and depth creep following mantas off the ridge.

Konservasi: Cleaning stations fail when divers crowd them; the low-and-still protocol is enforced by every good crew.

Nitrox: Layak di sini — profil berada dalam rentang di mana nitrox secara nyata memperpanjang waktu tanpa dekompresi (dengan pelatihan yang sesuai untuk menggunakannya).
