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 long and distinguished history of cave exploration, cave science, and cave conservation throughout California, and in other areas of the US and the world.
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.
