1.9 miles between O'Hair Park and San Andreas Fire Road, and 5.2 miles round-trip to Mt. Burdell
From: O'Hair Park or San Andreas Fire Road
To: The West entrance of Olompali State Historic Park
Climb through grasslands dotted with ancient oaks to spectacular vistas of North Bay ridges from the 1558-foot peak of Mt. Burdell. The largest of Marin County Open Space District’s holdings, these nearly 1600 acres of oak savanna and grasslands are interspersed with dense woodlands. Hikers and equestrians can begin from O’Hair Park and cross a Sensitive Wildlife Area on the Dwarf Oaks Trail. Mountain bikers join them at San Andreas Fire Road, and all users follow wide fire roads to the peak; the trails are steep and rocky, with little shade. Summers are hot here, so be sure to get an early start and come prepared.
Bicyclists not permitted on Dwarf Oak Trail. Can use interim route on San Marin Dr., San Andreas Dr., and the San Andreas F.R. to meet equestrians and hikers at junction of Dwarf.
