Caving – also known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland – is the recreational pastime of exploring wild cave systems (as distinguished from show caves). In contrast, speleology is the scientific study of caves and the cave environment.

Sometimes categorized as an "extreme sport", it is not commonly considered as such by longtime enthusiasts, who may dislike the term for its connotation of disregard for safety.

Caving is often undertaken for the enjoyment of the outdoor activity or for physical exercise, as well as original exploration, similar to mountaineering or diving. Physical or biological science is also an important goal for some cavers, while others are engaged in cave photography.

Canyoneering is the exploration of a canyon from point A to point B using a range of techniques that include hiking, scrambling, sliding, stemming, chimneying and rappelling. Imagine extreme hiking with a harness, a helmet and appropriate rope systems. Think reverse climbing and scrambling with a little butt-sliding. Canyoneering is the intimate exploration of forgotten Earth. It is poetry in movement.
