Most of Midpen’s 220 miles of designated trails are unpaved “wildland” trails in steep, rugged terrain. Approximately 65% of these trails are multiuse 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 a 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.

Public Meeting (virtual): Allowing E-bikes on Improved Trails and Roadways
Wednesday, August 12, 2020 at 7 p.m.

At this meeting, the Midpen board of directors will vote on the General Manager's recommendation to designate improved trails and roadways, most of which are paved, in Ravenswood and Rancho San Antonio preserves as open to class 1 and 2 e-bikes and to designate roads and parking areas that allow cars as open to all classes of e-bikes at all preserves. The agenda and report for this meeting will be available at openspace.org/board-meetings no later than 5 p.m. on Friday, August 7. 

E-bike Policy Evaluation
The Midpen board of directors reviewed e-bike policy options at the public board meeting on November 20, 2019. The board voted unanimously for staff to evaluate and propose a process to implement a one-year pilot program for class 1 e-bikes on select unpaved trails, including regulations enforcement and impacts on natural resources. Staff will also evaluate allowing class 1 and 2 e-bikes on designated paved trails and roads, using a phased approach. Click here to join our bike notification email list to receive updates.

Preserves open to mountain biking

Sharing the Trails

Midpen offers low-intensity recreational use consistent with resource protection and preservation. Many different users are out on the trails exploring open space.

To help make multipleuse trails work, each user should keep in mind the needs of others. Bicyclists should always yield to all other trail users. On wide trails, slow down and pass with care. When encountering equestrians and hikers on narrow trails, make your presence known well in advance, particularly when approaching from behind. Stop and wait for them to pass or signal you through. Yield to other bicyclists traveling uphill.

Access Guidelines

  • Helmets: Bicyclists are required to wear helmets, even when riding uphill, that meet the standards of the United States Consumer Product Safety Commission Standard for bicycle helmets, or ANSI or Snell-approved bicycle helmets on all Midpen lands. Helmet straps must be securely fastened when riding.
  • Speed limits: Control your speed at all times and obey the 15 mph speed limit (5 mph when passing or on blind turns). Racing and reckless riding are strictly prohibited.
  • Closed areas/off-trail use: Ride on designated trails only (those shown on Midpen maps for bicycle use). Closed area or off-trail use, including straying off the trail for jumps, “wallrides” and “woop-d-dos” is strictly prohibited.
  • Electric bikes (e-bikes): Electric powered bicycles are NOT allowed, except for use by individuals with a mobility disability, and only on trails where bicycles are authorized. Other Power-Driven Mobility Devices Policy
