HP Reef

HP Reef earns its Rainbow Reef nickname the moment a torch beam hits the walls: every overhang, chimney, and cave mouth is upholstered in blue, orange, and purple soft coral fed by the channel current. Gray reef sharks and eagle rays hold in the flow off the corners, dogtooth tuna slide past in the blue, and clouds of basslets shiver over the reef top. It is a protected site and a demanding one — when the tide runs hard the smart dive is a tight, guided line along the sheltered face.

您此行的高光时刻: Soft-coral-lined chimneys and caves; sharks and rays riding channel current

地形地貌: Steep-sided thila cut with caves, chimneys, and swim-throughs

水流: Sits in a channel mouth; currents can be strong and occasionally downward on the outside corners.

危险因素: Strong, occasionally down-welling current; depth creep along the wall.

保育: Protected marine area; reef hooks only on bare rock, never coral.

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）。
