while caves are fascinating environments, they still remain some of the most dangerous spaces where to venture, in rio like anywhere else - narrow passages, wet and slippery slopes, darkness, lose rocks, protruding ceilings are just some of the obstacles faced while caving.

darkness, narrow corridors, slippery surfaces, loose rocks, low ceilings, insects and humidity all contribute to the challenge and the importance of safety and proper advance planning.

in addition to general safety rules, we highly recommend bringing a flashlight, a helmet, and water on all spelunking outings.
