Cathedral Cave is a Gozo cavern dive built around a blue-lit chamber and a surface pocket inside the cave. The route mixes boulders, swim-throughs, and dome-like spaces, so it feels scenic and slightly theatrical rather than technical. Access is usually planned from shore or by boat depending on the operator and sea state. It is a good fit for relaxed planning, careful buoyancy, and divers who like overhead scenery without a full cave profile.

Key Hazards
Safety Notes
Overhead sections require cave-aware buoyancy, navigation, and gas planning; stay within training.
Community notes to help plan your visit.
Scuba Diving
A 15–25 m cave/cavern dive with swim-throughs, boulders, and domes; surfacing inside the cave is a key feature.
Freediving
Freedivers can use the chamber and surface pocket, but the overhead structure still calls for disciplined planning.
Snorkeling
This is better treated as a dive or trained cavern session than a casual snorkel stop.
