What does spelunking mean?
Spelunking is the recreational exploration of caves. It commonly involves entering caves on foot, examining passages, climbing, crawling, and learning about the underground environment. The activity is associated with caving clubs, guided expeditions, and the specialized equipment and safety practices required in caves. Spelunking can include both relatively accessible cave tours and technically demanding expeditions involving ropes, climbing equipment, and underground surveying. The word is used in both British and American English, though the activity may be more formally described in British contexts as caving or pot-holing. Its appeal lies in combining physical challenge with exploration, geology, and discovery: participants follow routes through spaces that are largely hidden from ordinary view. Although the term sounds old-fashioned to some speakers, it remains the clearest word for cave exploration undertaken as a hobby or sport.
