The San Diego grotto is affiliated with the National Speleological Society (NSS) and consists of about 50 cavers from the San Diego county area. Our grotto is very active in the exploration, surveying and conservation of caves throughout California, Arizona, Nevada, and New Mexico. If you have any questions, feel free to contact us.

Membership is $12 per year for NSS members, and $15 for non-NSS members. Membership includes a monthly subscription to the San Diego Grotto News. 1.
