Flic-en-Flac and Cathedral offers a diverse range of dive sites, from shallow beginner reefs to deep wrecks and an acclaimed cavern system at La Cathedrale. The topography shifts between reef walls, drop-offs, caves and the wreck of the Tian Xian. Turkey Moray, Spotted Eagle Ray, Indian Lionfish and Green Sea Turtle are all regularly observed. Conditions favour diving from late autumn through the cooler mid-year months, when visibility is at its best.

Water temperature peaks through the austral summer months from January to April, then cools noticeably through the middle of the year before climbing again in November and December. The cooler mid-year period from May to November draws the strongest diver interest, with the histogram peaking in May and November. Exposed boat sites can carry current, so conditions vary between the shallower beginner reefs and the deeper drop-offs and wreck.

Several sites are graded for beginners, including Aquarium, a reef and canyon dive accessible by boat, and the very shallow shore entry at Flic En Flac itself. Intermediate sites such as La Cathedrale and L'Eveille introduce walls and overhead environments, while Couline Bambous and the wreck Tian Xian are reserved for advanced divers comfortable at depth.
The area spans a wide range of site types. Shallower reef dives suit early-certification divers, while La Cathedrale offers a distinctive cavern and cave system with passages and chambers. Couline Bambous combines drop-offs, caves and artificial structures at depth, and the Tian Xian wreck sits deeper still as a dedicated advanced site.
Most sites are boat access, including all the major reef, cave and wreck dives. Shore entry is available at Couline Bambous and at the shallow Flic En Flac reef site. Divers without their own transport will want to confirm boat departure logistics locally, as no operators are currently listed in the area data.
