While the jewel hike at Jack London State Historic Park is the Mountain Trail to its highest point, another good hike is the Sonoma Mountain Ridge Hike.
The hike starts off on the Lake Trail to London Lake from the Upper Parking Lot. As you begin, you hike past a picnic area, winery ruins and the distillery and turn and hike past a vineyard. Follow Mountain Trail which is a service road next to the wooded area. We stayed on Mountain Road as we passed an intersection where another trail leads to the London Lake.
