Molokini Back Wall

Wrap around Molokini's rim and the friendly crater vanishes: the outside is a cliff in blue water, dropping past 60 m with nothing beneath your fins but darkening ocean. The dive is a drift along that face — black coral bushes and fans on the rock, jacks and the odd gray reef shark materializing from open water, eagle rays planing the wall, and in winter the constant creak and moan of humpbacks somewhere in the channel. There is no bottom to save a distracted diver, which is the site's entire discipline: watch the gauge, watch the group, and let the wall scroll past like landscape from a train.

您此行的高光时刻: A sheer 60-meter-plus face in open ocean; whale song through the water in winter; big-animal roulette in the blue.

地形地貌: A sheer volcanic wall plunging past recreational depth into open ocean

水流: Ocean currents wrap the crescent unpredictably; some days are still, some sweep.

入水方式: Live-boat drift along the crater's ocean face; groups stay tight and fly a DSMB for pickup.

危险因素: Bottomless exposure and depth creep; currents that change mid-dive; stay shallow enough that a mistake has somewhere to stop.

保育: Same conservation district as the inner bowl — the black coral on the face is protected and grows by millimeters.

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）。
