Port-Louis grotto-and-reef dive with a semi-open arch.
Boat access and the grotto layout make a local Port-Louis operator the normal setup.
La Cathedrale is a Port-Louis grotto-and-reef dive built around a bell-shaped cavern with an optional entrance, a semi-open arch, and a coral reef running on a north-south axis. It suits divers who like structured terrain, careful buoyancy, and a calm, methodical route through arches and reef life rather than a straight open-water swim.

Scuba Diving
Best as a guided boat dive with a bell-shaped grotto, optional entrance, and a semi-open arch on a reef line.
Freediving
Not a freedive-first site; the overhead grotto and boat setup make scuba the natural fit.
Snorkeling
Snorkeling is not the main appeal and does not capture the grotto-and-arch structure well.
