La Catedral (Puerto de la Cruz)

  • Max depth45 m

The dive

A rocky shelf with arches, vaults and caves reminiscent of the inside of a cathedral. There are coral gardens on the terraces; inside you see glassfish, lobsters and morays.

The deepest part lies at ~40–45 m: far beyond the Open Water limit (18 m). Plan depth and gas accordingly, or stay shallower with your guide. There can be current.
Profile and sections

A rocky shelf with arches, vaults and caves reminiscent of the inside of a cathedral. There are coral gardens on the terraces; inside you see glassfish, lobsters and morays.

The tourism board rates it 'Medium' and calls it adaptable to all levels, with the route set by experience and current.

Depth and profile
Descent to ~20 m, then arches, vaults and caves down to ~45 m; inside a cave ~20 m high. The tourism board gives 30 m, Macaronesian Divers -6 to -40 m.
Configuration
Large, light space with beams through holes in the vault: all configurations; bring a light (estimate).
DPV: Not DPV-suitable (estimate)
One large vault close to the harbour — a scooter adds nothing.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Oct 2026): the official dive-point pages of the Canary Islands tourism board (Hello Canary Islands: Tubo de Garachico, Cueva de Los Cerebros, La Catedral and Cueva de Matanza, with depth, level and pin), DIVE Magazine (15 Jan 2024), the websites of Sa Caleta Tenerife and Macaronesian Divers, the Spanish ministry's (MITECO) Natura 2000 panels and Diario de Avisos (May 2026) on the hyperbaric chamber. Pins come from Hello Canary Islands; the Cueva del Zorro, the Cueva de las Morenas and the Cueva de Ali Babá have no pin. These are guided boat dives into lava tubes, caverns and arches in the sea; certification and configurations are estimates. Rules change — check locally.
