Chimney

Chimney is an advanced dive site off Puerto de la Cruz on Tenerife's north coast, featuring a dramatic vertical chimney formation in the volcanic rock. Divers descend through this natural vertical shaft, experiencing the thrill of a controlled descent through a volcanic tube with light filtering from above. The chimney walls are decorated with encrusting organisms, sponges, and small crustaceans, while the exit opens onto an impressive reef populated by groupers, barracuda, and large schools of Atlantic fish. The northern exposure brings strong currents and rich marine life, but also challenging conditions that demand experience, good buoyancy, and familiarity with overhead environments.
