The Chapter's outings are a great way to get out and enjoy our beautiful Bay Area, the Sierras and beyond.

The Chapter's calendar is a good place to look for outings organized by the 3 Regional Groups and 13 Activity Sections in the Chapter.

Many of the Regional Groups and Activity Sections hold regular meetings, publish newletters, and maintain their own web pages. To find out more about them, visit their web pages by clicking on the links below.

All participants on Sierra Club outings are required to sign a standard liability waiver. If you would like to read the Liability Waiver before participating on an outing, please go to: http://content.sierraclub.org/outings/national/liability-release-and-assumption-risk.

We're ecologically minded locals, in our 20s & 30s, who like to hike all day and dance the night away!


The backpacking section sponsors between twenty and thirty trips annually, that range in difficulty from easy beginner weekends to up to two week long expeditions. Most trips are within California and Nevada, mainly to wilderness and scenic areas. You must get permission from the leader in order to join. Charges for trips are limited to the cost of permits and group meals. Want to go but don't know how to backpack? Courses in basic backpacking, lightweight backpacking, and leadership training are offered. Come, join us on a trip or at a monthly meeting.

Black Mountain Hiking Section

Discover and share your appreciation for wildflowers, photography, and the outdoors within our diverse community. Off the trail, come to our speaker series and dinners.

Day Hiking

The day hiking section offers many opportunities to view nature at its best, meet new and interesting people, and to just have fun. The section leads a hike every Saturday, rain or shine, within one of the bay area's state parks or preserves. Frequented locations include Big Basin, Mount Diablo, Open Space Preserves, Pinnacles, Pacheco Pass, and Henry Coe State Park. Most hikes are 15-20 miles long and have steep climbs. Everyone is welcome to join. See you on the trail!


Family Outings

A family outings program is available for parents with or without their children along. The bicycling or hiking events are usually on weekdays.

Gay & Lesbian Sierrans

GLS members share the enjoyment of the outdoors. We also offer the gay, lesbian, bisexual, and transgender community safe and supportive fellowship. Most activities are hikes but campouts are occasionally offered. Whether looking for friends, a partner, people to connect with, or recreation, this section offers a healthy pleasant way to socialize. GLS invites everyone, regardless of sexual orientation, to join.

Inner City Outings

Loma Prieta Paddlers

If you're new to the area, looking to improve your paddling skills or just want to paddle with an enjoyable group of fellow kayakers, join the Loma Prieta Paddlers. For over 25 years, our group has supported the paddling community by hosting weekly pool roll sessions, a full schedule of river trips and an annual whitewater slalom race. Club membership is easy; there are no club dues nor secret handshake to learn. We paddle the many rivers of California's Sierra Nevada Mountains and the coastal ranges.

Peak Climbing

Looking for a challenging outdoor adventure? Participating in one of the Peak Climbing sections many non-technical ascents in the true wilderness will give you just that. Activities are extremely varied and include: rock, snow, ice, crag and high summit climbing, cross country skiing, hiking the local hills and traveling abroad to climb. There are more serious trips for those with experience, and there are trainings and beginner trips for those new to the sport. Check out our newsletter, Scree.

Rock Climbing

Share your interest in technical climbing with members of the Rock Climbing section. The Rock Climbing Section is a perfect place to meet others of various abilities and ages who want to climb. Our two major social events are the Spaghetti Feed in July and a holiday party in December. Join our email list and find out about private trips on our website.

San Mateo Hiking

Our excursions are typically twenty to thirty people large—a great chance to get to know a group of like-minded people. We have trips three times a week, mostly on Wednesdays and Thursdays, lasting from late morning to early afternoon. Hike difficulty ranges from leisurely 1A's to challenging "double-star hikes" longer than 8 miles. Past favorites include Big Basin and Portillo Park.
