Find the best caving lessons, classes, and instructors at HeyKiki and learn how to go caving. Caving, also known as spelunking, is the recreational activity of exploring cave systems. People first began exploring caves in the past in search of shelter from the elements or from enemies, but as civilization developed over time it became more of a recreational pastime. Today people organize spelunking tours, where spelunkers must navigate pitches, squeezes, and water, often underground, and often by climbing or crawling. Caving is considered today as an "extreme sport," and proper equipment such as ropes, helmets, and headlamps must be used to ensure safety.
