Who We Are

We are cavers! We love to explore the wonders of the underground.

The San Francisco Bay Chapter (SFBC) is an internal organization of the National Speleological Society, often called grottos. Grottos are local groups of cavers who like to get together and go on trips to caves. The SFBC is a part of the Western Region.
