Bexar Grotto, chapter of the NSS

The Bexar Grotto is committed to the protection of caves and cave conservation activities.  These activities include exploration, education, restoration, protection, and assisting government agencies and private landowners in developing management plans for caves and karst.  Bexar Grotto members have contributed many hours of volunteer time and effort to study and protect these valuable resources and enjoyed themselves in the process!

The Bexar Grotto is a chapter of the National Speleological Society (NSS).  The NSS is a non-profit organization affiliated with the American Association for the advancement of Science.  The NSS was founded to advance the study, conservation, exploration, and knowledge of caves.

Since 1983 Bexar Grotto has provided a forum for cavers to meet and participate in various caving activities, including surveying/mapping, exploration, and conservation projects.
