Volunteers for Outdoor California

Happy people. Happy trails.

Welcome to 2026! We're in the middle of trail building season, come join us! Our next project is returning to Mt. Madonna in August (our first project of the season was there in April), then the East Bay Hills Benefit in September, and more to come!

Thank you Cathy Moyer, and Congratulations Duane Sheets! After about 20 years(!) our Founder and Executive Director Cathy Moyer has decided to step down - thank you Cathy for getting this all started and running things for many years! Our new Executive Director will be a familiar face to many of our volunteers - please welcome Duane Sheets! Duane is filling some big shoes - congratulations and good luck Duane in your new role.

Help us take V-O-Cal to the next level by donating today! Thanks to an amazing volunteer, we have set up a GoFundMe - Thank you, Brittany! Another volunteer (who has asked to remain anonymous) has made a $50,000 contribution to get the fundraising started. Our goal is to match his contribution with another $50,000 from the GoFundMe. Help make that incredibly generous donation just the beginning and enable V-O-Cal to keep building trails to the future. Please check out the GoFundMe page and our Donation page and share with all your friends.

Who are we? Volunteers for Outdoor California (V-O-Cal) is a volunteer workforce for large-scale trail maintenance and construction projects, habitat restoration, and related land stewardship activities on public lands in partnership with public agencies and other nonprofit organizations.

Season Sponsor Special Thanks to Bay Area Barns and Trails for their generous grants supporting the 2024, 2025 and 2026 V-O-Cal Project Seasons. BABT assists landowners and land managers with preservation and maintenance of publicly accessible Bay Area barns, stables, pastures, staging areas, horse camps, and trails.

Why volunteer with V-O-Cal? While there are many great Bay Area organizations that do some form of land stewardship, the V-O-Cal approach is a little different, and it is designed to complement the work of those other groups, extending the reach of other agencies and organizations while enlarging the overall pool of skilled volunteers. We work all over the region, from Monterey to the Trinity Mountains and from the coast to the western Sierra, offering volunteers a broad range of project types in a consistently well-organized fashion. The difference between V-O-Cal and our fellow land stewardship groups can be summed up in four categories: Scale, Duration, Planning, and Resource Focus.

Scale The average V-O-Cal project puts 75 - 200 volunteers to work on a single project.

Duration V-O-Cal projects are a full weekend long, starting on Friday and going through Sunday afternoon.

Planning Because of the scale of our projects, the logistics are important to assure that each volunteer has a satisfying experience and that the land manager is thrilled with the result.

Resource Focus Rather than focus on a single park, area, or land manager partner, V-O-Cal moves around Northern California and works with a broad range of partners throughout the region.

Become part of a volunteer workforce. Skilled and unskilled volunteers welcome.

Volunteers for Outdoor California believes that the quality of the experience is the most important part of any of its efforts. As a result, everything about the organization and our projects is designed to make sure that every volunteer has a great time and leaves with a genuine sense of accomplishment.

Camp in the most beautiful parks in California.  No making a reservation or worrying about food necessary.

Because we are doing work in these parks, we get special permission to camp in areas that often do not allow camping. We supply the meals on Saturday and Sunday, all you need to do is show up and pitch your tent!
