About Bale Grist Mill State Historic Park

1846 marks the construction of the water-powered grist mill preserved on this land. The mill runs on a large wooden waterwheel and stands as one of only two surviving water-driven mills west of the Mississippi River, giving visitors a working example of how grain was ground before mechanized power took over. The property sits between St. Helena and Calistoga, centered entirely on this single structure and its milling machinery.

Hours, fees, camping, reservations and closures are set by the park and change often. Check the official park site before you go.
