Grottos of the National Speleological Society (NSS)

With 10,000 members and 250 grottos (chapters), the National Speleological Society is the largest organization in the world working every day to further the exploration, study, and protection of caves and their environments, and foster fellowship among cavers.

For over 70 years, the National Speleological Society has promoted safe and responsible caving practices, effective cave and karst management, speleology, and conservation. Our members are bound together by their love of caves and caving and their desire to learn about the underground wilderness and protect it for future generations.

NSS membership offers worldwide caver camaraderie and networking opportunities and access to information about discoveries and developments in caving, speleology, equipment, and techniques through our publications, annual conventions, grottos and other internal organizations, and NSS-sponsored projects, expeditions, and surveys.
