About Black Rock
Black Rock Reef is a compact Naxos boat dive around a small rocky islet off Alyco Bay. The route favors steady navigation along a wall and reef edge, with enough variety to keep the circuit interesting without turning it into a speed run. It suits divers who want a focused island dive with clear structure, solid marine life, and conservative gas planning.

Scuba
Black Rock Reef suits scuba divers who like a compact rock loop, wall sections, and a longer route with clear landmarks.

Snorkeling is not the main use case here. The route only becomes interesting well below the surface.
