Bale Grist Mill State Historic Park, Calistoga

This restored mill, built in 1846, still works, and visitors can see its massive millstones in action when millers grind flour out of local wheat. Bale Grist flour, literally the "run of the mill," can be purchased at the mill when demonstrations take place. Check for the sign saying "Milling Today." Bale Grist Mill demonstrations are irregularly scheduled. Demonstrations are more frequent on weekends and in summer months. The smallish, tree-filled park surrounding the mill offers a welcome contrast to the car-interned.
