Marin County Parks and Open Space Department

The White Hill Open Space Preserve bridges the gap between the Cascade Canyon, Gary Giacomini, and Loma Alta preserves. The highlight of White Hill Preserve (390 acres) is the Blue Ridge Fire Road that passes over the summit of White Hill at an elevation of 1,430 feet. This road and the nearby Wagon Wheel Trail pass through impressive stands of manzanita and chamise above steep, rocky slopes. The rocks and soil in this area are predominantly serpentine. During spring, this landscape is quite picturesque with native grasses and wildflowers sprouting among the beautifully weathered stones.

To protect sensitive wildlife species, some trails in White Hill Preserve are subject to seasonal night closures. Please observe trail closure signs.


From Hwy 101 in Larkspur, take the Sir Francis Drake Blvd exit west past Fairfax and up White Hill. Trailhead is on the left before the crest of the hill.
