North Sonoma Mountain Regional Park & Open Space Preserve

Visit North Sonoma Mountain Regional Park & Open Space Preserve

In 2005, Regional Parks joined together with several public agency partners to realize the vision of a trail connection between Jack London State Historic Park and a new trailhead on the north slope of Sonoma Mountain.  Through a series of land acquisitions and easements, the properties were assembled together as the basis of a new park.  Construction of a new 4.5-mile multi-use trail and trailhead parking area was completed in the summer of 2012.

Four Sonoma County Agricultural Preservation & Open Space District properties were transferred to Regional Parks in the summer of 2014.  These four properties are being combined with a parcel owned by Regional Parks to create the North Sonoma Mountain Regional Park and Open Space Preserve.


Through a combination of land acquisition, property development, and infrastructure improvements, Sonoma County Regional Parks has collaborated with multiple agencies to bring the park to reality:

Project Partners

  • Sonoma County Agricultural Preservation and Open Space District
  • California State Coastal Conservancy
  • California Department of Parks and Recreation
