Welcome to the San Francisco Bay Chapter of the National Speleological Society

sfbc_patch_rgbWe love to explore, study, and promote the conservation and preservation of caves as a non-profit internal organization of the NSS (National Speleological Society). We explore caves, hold monthly vertical rope technique practices, and support various caving related activities.






Chapter meetings are held on the 4th Tuesday of each month* at The San Carlos Public Library at 7:30 PM SHARP.

Meetings start with introductions, meet and greet, leading to a 30 minute presentation, and end with member caving trip reports at around 9PM.

The San Carlos Library is located at:

610 Elm Street
San Carlos, California
