Babylon

Babylon is the dive Cayman regulars whisper about while tourists queue for the West Wall. A buttress leans away from the North Wall like a cathedral flying free of its nave, and the channel behind it funnels you past black coral thickets, wire corals corkscrewing into the dark, and sponges in colors that only exist below twenty meters. Off the face, the blue does its big-ocean trick: eagle rays, reef sharks, sometimes nothing but the vertigo of a 2,000 m trench under your fins. Distance keeps the crowds away; conditions decide the schedule.

您此行的高光时刻: The freestanding pinnacle, hanging black-coral gardens, true oceanic wall over the Cayman Trench.

地形地貌: A hanging garden on the North Wall: a pinnacle splits from the face, wrapped in black coral and rope sponges, over a sheer drop.

水流: Oceanic water; gentle most days with occasional along-wall set.

入水方式: A long run along the North Wall — usually offered by East End and North Side operators when seas cooperate.

危险因素: Depth over a bottomless face and boat-distance from help; conservative profiles and good surface cover.

保育: Remote North Wall site in marine-park waters; its condition reflects light traffic — help keep it that way.

高氧（Nitrox）: 在此值得使用——各潜点深度落在富氧空气（nitrox）能有效延长免减压时间的区间（前提是持有相应认证）。
