Ben WhiteThe San Gabriel Mountains Trailbuilders (SGMTB) is an all-volunteer public service organization dedicated to constructing and maintaining hiking trails in the San Gabriel Mountains' Angeles National Forest in Southern California.

The SGMTB, a 501(c)3 nonprofit organization, was founded in 1984 and works in close association with the U.S. Forest Service, Angeles National Forest.

We are committed to following environmentally-sound construction principles and working with conservation-minded individuals and agencies to preserve and respect the natural habitat, while at the same time, building trails to provide Angelinos with a wholesome and safe recreational experience as they enjoy the gift of our beautiful mountains.

Our regularly scheduled work days are the first, third, and fifth Saturday of each month. Come join us!
