The Bay Area Ridge Trail runs through the preserve, connecting Long Ridge with Skyline Ridge Open Space Preserve. This 13 mile section is one of the longest sections. It extends from Sanborn-Skyline County Park to the northern boundary of Russian Ridge Open space Preserve.
Long Ridge O.S.P. is over 1550 acres and contains ten miles of trails to explore. Many of the trails are old ranch and logging roads. The valley that Peters creek flows through was once part of an old farm site. This legacy is still evidenced by an abandoned apple orchard that still bears fruit in the fall. The preserve is bordered by private property. Please respect the boundaries and stay on designated trails. Sempervirens Fund provided major support for acquisition of portions of Long Ridge Open Space Preserve.
