Mount Diablo Volunteer Trail Work 

Welcome to the Mount Diablo Volunteer Trail Crew information page! The crew meets on the second Saturday of each month, from 8:30 AM to approximately 2:30 PM for regular trail maintenance and special projects, such as rerouting trails and finding solutions to prevent erosion. It would be impossible for the Park to provide this level of trail maintenance without the dedication of the Trail Crew volunteers, some of whom have been volunteering for ten or more years. There is a job suited for everyone, from light pruning to major rock moving projects. As an added bonus, the Trail Crew volunteers have a great time working together and many friendships have developed over time.

Prior to joining the Trail Crew, volunteers must complete the VIP (Volunteers in the Park) orientation. There is no expectation for a commitment in terms of the number of days or hours worked. Each work day presents a new challenge and gives volunteers a chance to visit all parts of the mountain and become familiar with its history and the amazing variety of flora and fauna.

Other opportunities to volunteer for trail maintenance include attending the annual Earth Day or Trail Day projects in the spring, and the National Public Lands Day in the fall. 

If you are interested in joining the Trail Crew and/or would like to get placed on the email list for information on scheduled workdays, please contact
