North Sonoma Mountain Regional Park & Open Space Preserve Master Plan

What & Why?

Regional Parks has worked with several public agency partners to make a 4.5 mile 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.

Four properties were transferred from the Open Space District to Regional Parks in the summer of 2014 and combined with a parcel owned by Regional Parks to create the North Sonoma Mountain Regional Park and Open Space Preserve.

Park opened: Valentine's Day 2015
