San Gabriel Mountains Trailbuilders Trailbuilders

The San Gabriel Mountains Trailbuilders (SGMTB) is an all-volunteer, 501(c)3 non-profit public service organization dedicated, to constructing and maintaining hiking trails in the San Gabriel Mountains Angeles National Forest (San Gabriel Mountains National Monument) in Southern California.

We work the 1st, 3rd, and 5th Saturday of every month, and we work special projects which are not scheduled. Please email us to get on to the mailing list to keep informed about scheduled and special projects! Email Ben at

Although the Trailbuilders' primarily task is maintaining hiking and nature trails throughout the Los Angeles Gateway District of the San Gabriel Mountains, we also perform bridge building and repairs across hiking trails, fire mitigation activities (such as removing combustibles around camp sites,) removing or covering spray paint vandalism, and repairing or replacing trail signs.

U.S. Forest Service All volunteers receive extensive safety training and technical experience working in the forest so that the work that we do is done safely and professionally. We invite people to join us for our work efforts, whether they are Boy Scouts, Girl Scouts, youth groups, or individuals who want to assist the outdoor community by repairing and maintaining hiking trails, everyone is welcome! It's truly a great way to get exercise and enjoy the outdoors. You not only receive healthy exercise but a wonderful sense of self-worth by contributing to the preservation of the San Gabriel Mountain Trails which are used and enjoyed by thousands of hikers each year.

Trailbuilders Volunteers who wish to work with our organization are welcome!! All volunteers will be supplied with the necessary tools, gloves, hard hats, safety glasses and equipment for the that particular day.

Volunteers are required to wear a long-sleeved shirt, long pants, hat, sturdy walking shoes, or hiking boots, sunglasses (optional), sunscreen, water for the day, snacks and a lunch. Be prepared to work an 8-hour day.

All individuals under 18 must be accompanied by a responsible adult! Transportation must be provided by the volunteer to the job site and back. (The Trailbuilder's Minor Policy is located at SGMTB MINOR POLICY (Word Document).

Occasionally, First Aid Preparedness Meetings are held, as well as Safety Refresher Meetings, both presented by members of the US Forest Service.

This web site covers how and when to volunteer, and provides information on projects that we have performed in the past as well as up-coming projects that volunteers are needed for. The web site also occasionally contains information about potential Girl Scout Gold Award projects and Boy Scout Eagle Projects which are needing to be done in the forest and about which you may contact us about if you decide you might want to perform them.
