The Bexar Grotto is a registered 501(c)(3) nonprofit and a local chapter of the National Speleological Society (NSS). We have contributed countless hours of volunteer time and donated thousands of dollars to study, explore, and protect valuable cave resources. If you would like to get involved with our friendly group of cavers and enjoy some exciting caving activities, contact us or attend a meeting!
