Marin County Open Space District
BICYCLES ON OPEN SPACE
The District maintains approximately 70 miles of fire protection roads and service roads exceeding eight feet in width which are open to bicycle use. The Open Space District Code specifies that bicyclists must operate their vehicles at speeds which do not exceed 15 miles per hour and reduce their speed to 5 miles per hour when approaching blind turns or passing others using open space lands. Bicycles are not permitted "off-road" or on "single-track" trails. The District road network offers a variety of open space experiences, from expansive and panoramic views of the bay area to intimate and unique environments. Bicyclists are encouraged to explore the diverse opportunities available on open space lands.
