From a purely aesthetic view, caves offer a range of physical and mental challenges and often very impressive or beautiful scenery found nowhere else.
Scientifically they are fascinating, with studies ranging across geology, hydrology, Biology, palaeontology and Archaeology. Some of these examine evidence preserved by being underground, leading to assessments of palaeoclimates and climate changes.

Geologically, their sediments and speleothems preserve palaeoclimate evidence. Palaeontologically, many caves preserve animal remains. Archaeologically, some caves preserve human remains, artefacts or art.
A person who likes to explore caves is called a "caver" - if he or she is studying caves' scientific aspects, a "speleologist". Caving is the amateur activity or sport of exploring caves. It was once known as 'spelunking' in the United States and Canada and 'potholing' (from the old Northern English term "pothole" for a cave whose entrance is a shaft open to the surface) in the United Kingdom and Ireland. A person doing this activity is now generally a Caver: Spelunker and Potholer have fallen out of use though "Pothole" survives in a few Northern English caving-club names.. Speleology is the term for the study of caves, whether by amateur or professional scientists.
