About this site

Bajo Negro, also known as Black Rock, is a pinnacle near the Bat Islands, in the Catalina Islands area. It is covered in corals and sponges, and divers circle it from bottom to top, passing large schools of fish and rays on the way to the surface. The depth is about 30 to 120 feet (9 to 37 metres), with a maximum of around 100 feet (30 metres) quoted.

Eagle rays and devil rays are seen, and flying mantas turn up regularly. It is often affected by strong currents and surge, so it is a dive for advanced divers.
