The rim opens like a dark mouth beneath a blue Veracruz sky: guides check ropes, the group leans into a cool draft that smells faintly of river and wet rock. Swifts and swallows wheel above as the first rappel drops toward a ledge inside a 45‑meter diameter pit; beyond that the route continues down an 80‑meter vertical shaft to an underground lagoon fed by the Coatl River and a 60‑meter subterranean waterfall.

Be rope‑ready
Even with instruction included, arrive with basic comfort on ropes—practice knotwork and body positioning beforehand if possible.
Waterproof your kit
The lower gallery is wet; use dry bags for electronics and a waterproof headlamp cover to keep spare lights dry.
Layer and expect humidity
Temperatures drop inside the pit; bring synthetic layers that dry quickly and a lightweight insulating midlayer for the ledge.
Protect cave life
Avoid touching formations, keep noise to a minimum near wildlife roosts, and pack out all waste to protect fragile subterranean ecosystems.
Full‑face or mountaineering helmet
Protects against rockfall and contact during vertical maneuvers.
Headlamp with spare batteries
Hands‑free lighting is critical for movement in dark passages and for evening camp tasks.
Rope‑compatible gloves
Provides grip and protects hands during rappels and rope handling.
Sturdy waterproof hiking boots
Support for steep approach hikes and stability on wet, uneven cave rock.
