Marin County Parks and Open Space Department

Community Volunteer Days

Volunteer days are for people who seek hands-on land stewardship experiences. We provide a forum for neighbors to work together to take care of our shared parks and open space lands and resources. Join us to discover your outdoors, meet people, and to give back to the special places where you hike, ride, explore, and play. We guarantee your experience will be meaningful, rewarding, and fun.

Projects focus on habitat restoration, trail improvements, and maintenance. The work varies in physical demand, but for most events, we provide a variety of activities suitable for all ages and abilities. Beginners, children, and seniors are welcome. Activities requiring heavy physical exertion and/or that occur in steep or hazardous areas are noted in the event descriptions.

We provide water, gloves, tools, and training. You may want to bring snacks or a lunch. For special events, we provide morning treats, coffee, lunch, and sometimes raffle prizes. Always bring a water bottle, and wear sturdy shoes and comfortable, layered clothes.
