San Pedro Valley County Park is also supported by an active volunteer group known as the Friends of San Pedro Valley Park.  These volunteers staff the park's visitor center and provide various programs and activities that help Park Rangers maintain the facilities and the environment of this County Park.

A large and varied number of volunteer activities take place all year long at San Pedro Valley Park as part of the Parks Department's Volunteer Program. Individuals, groups, families and organizations can take part in trail construction, exotic plant removal, habitat restoration, trail patrol and other beneficial and rewarding projects. 

If you are an individual or an organization interested in getting involved please contact the San Mateo County Parks Volunteer Program.
