Nearly two decades and $21 million in the making, the 1,100-acre Taylor Mountain Regional Park and Open Space Preserve opened to the general public for the first time over the weekend.

The Sonoma County Board of Supervisors on Tuesday approved a plan meant to guide the future look and feel of a regional park on Taylor Mountain overlooking Santa Rosa. The blueprint for the 1,100-acre property includes 17 miles of trail for use by hikers, equestrians and cyclists, camping and picnic sites, five trailheads with restrooms and future plans for a visitor center, small event venue and an eight-room inn, given interest from a private partner.

The long-awaited rollout of a regional park on Taylor Mountain, one of Sonoma County’s largest swaths of open space overlooking Santa Rosa, is starting to take shape.
