Broken Rock

Broken Rock is named for the fissure that splits the pinnacle end to end: a canyon a few meters wide and up to ten deep, its walls upholstered with sea fans and whip corals that sway as the tide breathes through. Swimming the gap single file, with an eye on surge and fins off the walls, is the signature moment. Around the outside, terraces hold morays, turtles, marbled grouper, and drifts of anthias, and the sand at the base is worth scanning for rays. Photographers burn entire dives inside the crack.

您此行的高光时刻: The fan-lined canyon swim; turtle and moray terraces around the rim

地形地貌: A thila cleaved in two by a narrow canyon, walls hung with fans and whip corals

水流: Current across the canyon mouth decides whether the split can be swum; guides check before committing groups.

危险因素: Surge in the canyon; overhead-feeling terrain in the narrowest sections.

保育: The canyon's fans are fragile and slow-growing: perfect trim or stay out of the split.
