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.

Key Hazards
Safety Notes
Keep buoyancy tight over the sand, carry a torch for night dives, and move slowly so you do not stir silt or bump fragile critters.
Access Restrictions
Some entry points depend on resort permission, and rocky shore footing makes booties useful for shore entries.

Plan for the local Mabini Dive Pass/environmental fee and carry cash for resort and boat logistics.
