we strongly encourage all hikers to enjoy rio's mountain trails, caves, and caverns accompanied by an experienced and certified speleologist guide. 

further to the extra safety hiking and speleologist guides can provide, professional guides are fluent in portuguese and would be indispensable in case of an emergency to communicate with rescue crews.

important: speleology, spelunking, cave exploration, climbing, hiking, or any other similar activity is subject to risks of serious accidents, including death - people who do not possess proper hiking or climbing techniques, experience, and/or are not in excellent physical shape must hire or consult an expert trainer or guide for safety.
