Caving is a great adventure, there are unique challenges from many disciplines including bouldering, fixed rope ascending/descending, logistics, navigation, cartography, first aid/rescue, communication, psychology, leadership, etc. You tend to spend a lot of time in cold, dirty, cramped spaces, but the rush of exploration and gravity of danger make it quite exciting and rewarding too. I found the camaraderie to be fantastic, there’s local clubs all around the world and the community is pretty small and tight knit, it tends to draw a somewhat unusual group of individuals. Perhaps how rock climbing or scuba diving felt in the earlier days, pushing your limits doing something that most people find pointless and/or terrifying.
