Volcanic wall dive with rich macro life.
Rocha Negra is a volcanic wall dive off Lagos with dark rock relief, ledges, and crevices that hold plenty of small marine life. It is usually approached as a boat dive and rewards slow buoyancy control rather than fast cruising. The wall carries gorgonian growth and is known for octopus, eels, nudibranchs, cuttlefish, and crabs. Calmer days make the site feel more relaxed, while the rock face and shaded pockets keep it interesting for careful macro searching.

Safety Notes
Use good buoyancy near the wall, bring a torch for shaded pockets, and check sea state before committing to the dive.

Scuba Diving
Treat Rocha Negra as a slow multilevel wall dive. Good buoyancy helps around the dark rock, and a torch is useful for the shaded recesses.
