La Catedral

The rock here narrows as you go, column-like walls closing in until the canyon comes to a point at the bottom. Kneel there and look up: with the right light, beams drop through skylight holes in the roof high overhead, and for a moment the space genuinely reads like the inside of a cathedral. Dives typically start around an 18-20 metre shelf, with terraces of coral growth along the way down, before guides pick a route depending on the day's current and the group's experience. One common option descends toward 30 metres and climbs back up inside a vertical tunnel rather than retracing the same path. Deeper routes push to 40 metres and beyond when conditions allow. Island grouper and moray eels, including the brown moray, are common enough along the walls that they barely react to a passing diver, and glassfish gather in loose clouds wherever the rock offers shelter.

This is the single dramatic set piece of the Puerto de la Cruz cluster: one chamber, one moment of standing at the bottom of a canyon and watching daylight fall through the roof in a way it does nowhere else nearby. It isn't a tunnel to transit or a maze of passages to work through, just a narrowing space built around that one view. The name has caused genuine confusion over the years. A nearby cave-and-canyon system, a completely different dive, gets mislabelled "La Cathedral" in some Spanish and English-language guides after an old translation error, and the two are still mixed up by divers researching the area beforehand. This site, named by the discovering centre's founder in 1994, is the real one. If an operator or a guidebook calls a maze of tunnels and passages "the cathedral," they mean somewhere else, not this dive.

A torch belongs on this dive even though the main chamber lets in natural light; the connecting passages and tunnel sections don't. Depths of 30-40 metres are common on the fuller routes, so Advanced Open Water is the practical minimum, and a Deep Diver specialty is worth having for the deeper options. Current runs medium to strong at times, especially in summer, and the guide's read of the day's conditions decides which route the group takes. A 5-7mm wetsuit depending on the season is the standard call. Atlantik, the centre that named the site in 1994, runs the boat trip out, about 5-10 minutes from the harbour.
