Marin County Parks and Open Space

Marin County Open Space lands enhance our communities by allowing us a beautiful place to hike, run, ride and play. These preserves surround our homes and increase their value aesthetically and monetarily. They give to us personally and improve the quality of life in Marin. Volunteering is your opportunity to give back. Most preserves are located in the wild land urban interface. This means that they are right next door to you. As stewards of this land that makes us your neighbor. Please join us and your other neighbors in improving the land that we all own and enjoy.
