The Southern California Grotto is a chapter of the National Speleological Society, and was chartered in 1949. We’re one of the oldest grottos in the NSS, and have a distinguished history of cave exploration, cave science, and cave conservation throughout California, North America, and the world.
Meetings
The Southern California Grotto meets the first Tuesday of each month at 7:30 p.m. at the Beckman Institute Auditorium at the California Institute of Technology (Caltech) in Pasadena.
Meetings are a great opportunity to meet other Grotto members, learn about caves and caving, and get involved with grotto caving activities. Each meeting features a slide show on recent trips and activities by Grotto members, or other presentations about caves or caving.
Visitors and new cavers are always welcome to attend. Please stop by!

Conservation Projects
The Grotto prides itself on contributing to conservation projects in California and across the globe.
Cave Access
Southern California Grotto members prepare to be safer and more skilled cavers together. Many caves require vertical skills to explore. The grotto holds single rope technique (SRT) practices, knot and anchor practice nights, and other events to support skill-building and make caving safer.
