The dive

Naval is open water with a cavern line: a relaxed first dive or trim dive, also for non-cave divers (guided). Along the way you see fossil coral, tetras and turtles.

Naval is open water with a cavern line: a relaxed first dive or trim dive, also for non-cave divers (guided). Along the way you see fossil coral, tetras and turtles. The cenote is the neighbour of Casa Cenote.

Practical: whether you may dive here independently without a guide is something to ask.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (CREER, cave-ha.com, opencaves.info, PSAI/QRSS, dive centres; Sept 2026). Map pins are Google Maps or opencaves.info locations (usually the entrance/car park); Ho-Tul, Camilo, Odyssey and Aerolito (Cozumel) have no pin, the Muyil pins are estimates. Drive times are calculated by road for each stay (OSRM, OpenStreetMap; normal traffic, spot-checked against Google Maps within about 4 min); ~ = estimate. Rules, status and fees change often — check locally.
