Great White Wall

On the right tide, this wall does something no aquarium can fake: thousands of soft-coral colonies inflate at once and an entire vertical reef turns the color of fresh snow. Divers drop through a tunnel in the reef crest, emerge onto the face, and descend alongside a slope of white that keeps going well past sensible depth. The temptation to follow it is the site's real test. Anthias and fusiliers work the edge of the current while the corals feed. When the tide is wrong the wall looks gray and deflated, which is why guides refuse to dive it on a schedule rather than a tide table.

您此行的高光时刻: The white soft-coral face at full feed; the tunnel entry; blue-water depth vanishing below the wall.

地形地貌: Sheer wall in the Somosomo Strait, its face carpeted in pale Dendronephthya soft coral

水流: Needs running water for the corals to open, but too much makes the wall unworkable; operators pick the window.

入水方式: Timed to the tide; the classic route enters through a tunnel in the reef that exits partway down the wall.

危险因素: Depth creep along a featureless white slope; current changes mid-dive; the tunnel demands basic overhead composure.

保育: Soft corals shred under a single misplaced fin: trim flat, stay off the face, and leave the wall as inflated as you found it.

高氧（Nitrox）: 在此值得使用：这些潜点的深度范围内，富氧空气（nitrox）能有效延长免减压停留时间，前提是您已接受相关培训。
