Many people enjoy the trails at Mount Diablo State Park for a variety of reasons. We have pride in the access they provide to the beauty of the mountain and the surrounding views. It is not until a trail becomes blocked by a downed tree, over grown with vegetation, or the tread becomes difficult to negotiate that one thinks about trail maintenance.

What is Involved ?

Family members, friends, groups, and co-workers are encouraged to form a team that will agree to maintain a trail or a portion of trail for one year. In most cases the team can choose their trail. The Park will supply the trail tools needed to accomplish the work. Trail training will also be provided by the Park, or an experienced Crew Leader. The adopting group will work at it's own pace and schedule within a recommended time frame.

Adopter's Responsibilities

Each team will appoint a Crew Leader for every ten members. The Crew Leader will act as a liaison between the team and the Trails Coordinator. The Crew Leader will demonstrate the ability to lead a Trail Crew in a safe responsible manner; and be familiar with trail maintenance guidelines and operations regarding volunteers. Training for Crew Leaders will be provided.

We ask that the trail be inspected two times a year. Once after winter to assess storm damage; and once in late spring to monitor vegetation growth. The inspections will be followed up with a written log of findings to the Trail Coordinator. This log will help with scheduling work and deciding which tools will be needed.
