More than 1,000 volunteers donate their time, energy and expertise to Sonoma County Regional Parks each year. Volunteers build trails, lead interpretative hikes, maintain campgrounds, patrol park trails, build fences and much more. Groups from the Boy Scouts, local businesses and schools also spend thousands of hours maintaining our parks. We invite you to discover the parks through our volunteer program. We strive to match your skills and interests to a volunteer position that helps us: Enhance the quality of life in Sonoma County, Provide recreational, social and cultural opportunities to the public, and Preserve, conserve and restore our natural, scenic and historical resources.
