Wade through a turquoise underground river and pass under ancient stalactites on a guided Río Secreto tour. This accessible cave-walking experience combines geology, Mayan history, and a regional buffet.
More ways to explore the area's outdoor wonders
You step off the trail and the jungle narrows; humid air tugs at your shirt as the path lets you into a cool, low-lit doorway where an underground river waits. Headlamps carve bands of silver across black water as your guide leads the group into glassy galleries of translucent stalactites and dripping columns. The cave feels alive—the water nudges your calves, condensation beads like breath on the rock, and bats flicker in unseen chambers.

Wildlife
History
The Maya regarded caves as entrances to Xibalbá (the underworld) and used local cenotes for rituals; Río Secreto’s galleries preserve mineral formations and traces of ancient reverence.
Conservation
Río Secreto operates with strict no-touch policies, wetsuit and gear protocols, and limits on group size to protect delicate formations and the aquifer—follow guides and use only biodegradable products.

Wear secure water shoes
Trails and cave floors are slippery—water shoes with good tread keep you steady during wading and short swims.
Leave cameras behind
Cameras and cell phones aren’t allowed inside the caves to protect formations and for safety—use the official photos offered after the tour.
Hydrate and eat lightly beforehand
The underground section is cool but the jungle approach can be humid; bring water and avoid heavy meals right before entering the caves.
Book early-morning departures
Early tours have fewer people in the galleries and cooler conditions on the surface before the lunch buffet.
Closed-toe water shoes
Secure footing on slick rocks and trails—often provided but recommended to bring your own fit.
Quick-dry clothing and swimsuit
Wear layers that dry fast; a swimsuit beneath clothes speeds transitions from cave to buffet.
summer
Biodegradable sunscreen
Protect skin for above-ground sections without contaminating the cenote and reef systems.
summer
Small dry bag or ziplock
Keep your wallet, meds, and a dry change of clothes protected during transfers and on return.
