The Cathedral

Flic en Flac's signature dive drops down a coral-crusted wall into a vaulted cavern where the site earns its name: light falls through openings in the ceiling in tight, angled beams, and divers hang in a blue-lit nave watching soldierfish and sweepers circulate along the walls. Lobster pack the crevices, morays and scorpionfish hold the ledges, and outside the entrance the wall carries on past sponge-crusted overhangs toward 30 meters. Timing matters (surge amplifies inside on big-swell days and the cavern rewards small groups), but on a clean morning it is the west coast's best hour underwater.

您此行的高光时刻: Light beams inside the cavern; lobster-packed crevices; sculpted wall terrain

地形地貌: Fringing-slope wall cut by a large cavern, arch, and chimney formations

水流: Generally calm on the leeward west coast; surge reaches the cavern when swell wraps in.

危险因素: Overhead environment in the cavern, surge, and depth at the base of the wall.

保育: Fins and gauges scar cavern walls fastest: trim tight in the confined sections.

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。
