I'm actually upset I never took the time to hike here before. What a gorgeous spot! I would advise to have your own map when choosing your adventure as there wasn't much signage. There was a nice diversity of easy to moderately difficult patches.
This section of Highway 12 is the best part of the Valley of the Moon. Kenwood is where the City of Santa Rosa begins to fall behind you and the vineyards, wineries and stately walnut and oak trees line the roads. Traveling south through Kenwood, views open up to the Maacama mountains, home of Sugarloaf State Park and Mt Hood Regional Parks. The closer to Glen Ellen you get, the closer the hills and trees become. Glen Ellen has attractions too: Jack London State Historic Park, Boyes Hot Springs, and a number of eateries and wineries. The Sonoma Mission Inn and Spa is located just south of Glen Ellen. Small, winding county roads can take you up into Bennett Valley and back into Santa Rosa. Some of the smaller roads have little or no shoulder, although the alternative is the relatively high-traffic (though scenic) Highway 12.
