Sugarloaf
About
Sugarloaf is a summit of 1,640 feet in California's Sonoma-Lake Napa Unit, about 3 miles from the town of Green Valley. Spring and fall are the most comfortable times to go. Typical averages from a nearby weather station show May highs around 77°F and October highs around 78°F, while winter brings about 12 wet days a month. That station sits well below the summit, so temperatures up top run cooler. Several trails start close by. Thatcher Rim Rock Trail and Chaparral Trail are each about 0.4 miles away, and the Skyline Trail (Bay Area Ridge Trail) is about half a mile off. For time on the water, Suisun Creek is roughly 6 miles away.
