The San Francisco Bay Area Rainbow Sierrans is an outings and conservation club for gay, lesbian, bisexual, transgender, and queer people, as well as our friends and allies.

We are an official activities section of the San Francisco Bay Chapter of the Sierra Club. Founded in 1986, we were the Sierra Club's first gay and lesbian activities section. We're still one of the largest of a growing number of GLS chapters around the country.

We sponsor a variety of activities offering something for almost anyone who enjoys the outdoors. Our outings run the gamut from easy urban strolls to vigorous peak hikes; relaxed car camping to demanding wilderness backpacks; and naturalist-led walks to hands-on restoration and trail maintenance. Everyone is welcome on our outings, whether or not they have joined Rainbow Sierrans.
