Marin County Parks and Open Space Department

The Marin County Open Space District (MCOSD) manages approximately 270 miles of fire roads and trails on 34 open space preserves. Certain fire roads and trails are temporarily closed because of wet weather conditions, natural hazards, wildland fire, construction activities, and/or resource restoration projects. Fire roads and trails are closed to protect natural resources and user safety. Depending on site conditions, closures may affect some or all uses including bicyclists, equestrians, pedestrians, and vehicles.

MCOSD posts closure signs at trailheads to notify visitors of current use restrictions and to remind visitors to use alternate routes. Please cooperate with closure restrictions while visiting MCOSD lands; violators are subject to citation. Conditions and closures may change without notice on a daily basis due to weather, natural hazards, wildland fire, and/or MCOSD activities. Visit related pages to learn about safety, MCOSD rules and regulations, and MCOSD policies.
