Grass Valley, CA

Grass Valley is a Sierra Nevada foothills city in Nevada County, with roots in the California Gold Rush. Originally known as Boston Ravine and later Centerville, it grew around hard-rock mining, and Empire Mine State Historic Park preserves one of the area's defining gold-mining sites. Today Grass Valley mixes historic downtown buildings, arts, outdoor access, and a growing wine scene. It feels like a mountain foothills town with real history under the surface, not just scenery.
