Caving is an age-old hobby that brings people together to explore the worlds that exist beneath our feet. The National Speleological Society (NSS) is a member of AGI and promotes responsible and safe caving practices. If you've never been caving, you can explore caves with one of the over 250 NSS chapters called Grottos. Before you do, read through their updated Guide to Responsible Caving to review what skills and gear are necessary, but also how to be respectful of the cave, cave environment, creatures and cave owners.
