Drop Off

The Drop Off is Sipadan's thesis statement: you wade off a beach, and the bottom is 600 m away. The wall falls sheer from the reef crest, hung with fans and soft coral, and life uses every meter of it. Turtles ascend past divers like commuters on escalators, whitetips nap on notch ledges, batfish and sweetlips loiter under overhangs, and jacks boil bait against the surface with the beach in the background. The famous cavern mouth opens partway along. As a first permit-day dive it recalibrates expectations, and as a last one it is the image people carry home.

您此行的高光时刻: A 600 m wall starting at the beach, constant turtle traffic, the cavern entrance en route

地形地貌: Vertical wall from ankle depth into roughly 600 m of water

水流: Often the island's calmest marquee site, with gentle along-wall movement.

入水方式: Steps from the island's jetty; the wall begins where the sand ends, within meters of shore.

危险因素: Bottomless wall a fin kick from shore; depth discipline from the first minute.

许可证与规定: Permit day required.

保育: Jetty-adjacent and permit-capped; surface snorkeling happens under the same park rules.

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）。
