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.

Khoảnh khắc bạn đến vì nó: A sheer 60-meter-plus face in open ocean; whale song through the water in winter; big-animal roulette in the blue.

Địa hình: A sheer volcanic wall plunging past recreational depth into open ocean

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

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

Nguy hiểm cần lưu ý: Bottomless exposure and depth creep; currents that change mid-dive; stay shallow enough that a mistake has somewhere to stop.

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

Nitrox: Đáng dùng ở đây — các hồ sơ nằm trong khoảng độ sâu mà nitrox có thể kéo dài thời gian không dừng một cách thực sự có ý nghĩa (khi đã được đào tạo sử dụng).
