Most of the District’s 220 miles of designated trails are unpaved “wildland” trails in steep, rugged terrain. Approximately 65% of these trails are “multiple use” trails and are open to bicyclists, which is the highest ratio of trails open to bikes among parks and open space in the Bay Area. Many of these trails are also single-track trails, providing bicyclists with a more technical experience.

Please Note: Activities may not be designated on all trails within the Preserve-- always refer to the map and trail signage for where the activity is permitted. Some trails are subject to seasonal closures, always check trail conditions and refer to signage.
