Select participants and date
You climb down a wooden ladder into a cathedral of light—slashes of sun through jungle canopy turning the water to glassy turquoise. The air smells of damp limestone and leaves, and the first breath underwater is an odd, quiet astonishment: columns of rock loom above, stalactites reach like frozen fingers, and faint currents fold a silver veil where fresh water meets salt in a halocline.

Adventure Tips
Bring your certification card
Evidence of open water certification is required at check-in—digital copies may be accepted but bring the original if possible.
No flying after diving
Avoid air travel for at least 12 hours after your dives to reduce decompression risk.
Use reef-safe sunscreen
Apply biodegradable sunscreen before arrival to protect sensitive cenote ecosystems.
Protect your camera and trim
Sediment in caverns kicks up easily—use low-profile gear and practice buoyancy to avoid stirring silt.
Local Insights
Wildlife

History
Cenotes were crucial freshwater sources for the Maya and were often sites of ritual offerings; the Yucatán’s cave systems also preserve fossils and archaeological materials.
