Secret Bay is Anilao's black-sand macro slope.
Secret Bay is Anilao's black-sand macro slope, built for slow searching rather than big-reef scenery. Divers come here for patient critter hunting, where careful buoyancy and a guide who knows the slope matter more than speed. Most trips run by boat from the Anilao resort strip, with shore entry possible from nearby resorts. Dry-season conditions are usually the easiest, while wetter months can bring a rougher feel and a bit more current.
