Manza Dream Hole

Dream Hole is a keyhole through the Manza reef plate: a chimney that swallows divers in single file at five meters and releases them through a window in the wall at around twenty-five. Sweepers pack the shaft in shifting curtains, torch beams strobe across them, and the exit arrives as a rectangle of violent blue that makes every photographer stop mid-column. Outside, the Onna coast wall carries fans and reef traffic back toward the boat. The dive is short, vertical, and theatrical, and it demands the buoyancy to descend a tube full of fish without touching anything.

危险因素: Overhead environment in the shaft and queueing divers; commit only with the group briefed order.
