To explore, enjoy and preserve the nationís forests, waters, wildlife and wilderness

Come join us on our hikes. We love to have non-members join in.

We are Sierra Club members who explore the many trails in the SF Bay area every Sunday, with potluck dinners later in the evening. We have short 1A hikes and longer 2Bs that have lots of ups and downs. We also go backpacking, do mule trips, biking, and other events informally scheduled.
