Parks and Open Space

Marin County Parks is responsible for preserving, protecting and enriching the County’s regional and community park and open spaces through educational programming, climate change adaptation.


Dedicated to educating, inspiring, and engaging the people of Marin in the shared commitment of preserving, protecting, and enriching the natural beauty of Marin's parks and open spaces, and providing recreational opportunities for the enjoyment of all generations.


Embraced by the Pacific coast to the west and San Pablo Bay to the east, Marin County is a remarkably beautiful place, with an abundance of parks and open space preserves, reflecting the county’s rich heritage of land conservation. Through decades of hard work, residents, neighborhoods, organizations, and government have protected tens of thousands of acres of open space, hundreds of acres of parks, and miles of scenic trails that have become community treasures, adding immeasurably to the quality of life enjoyed in Marin. Learn more about Parks.
Throughout Marin County are 34 open space preserves that harbor unique species and ecosystems and provide visitors a chance to experience some of the most treasured landscapes in northern California. Vegetation management goals include the protection of sensitive habitats, reducing fire fuel hazards, managing invasive plants, and providing safe and sustainable recreation opportunities.
Marin County Parks continues to improve the percent of defensible space maintained on county lands adjacent to private properties, to reduce wildfire risk for Marin communities.
