published by the instituto municipal de urbanismo pereira passos, with the prefecture of the city of rio de janeiro, this map shows the maciço da tijuca.

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

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