Just north of St. Helena in California’s Napa Valley, Bale Grist Mill State Historic Park is a beautifully preserved glimpse into Gold Rush–era innovation. This living history park features a restored water‑powered grist mill dating to 1846, historic orchards, scenic creekside trails, and engaging demonstrations—a delight for history buffs, families, and outdoor enthusiasts.
What Makes Bale Grist Mill Unique
Bale Grist Mill is one of only two remaining water‑driven grist mills west of the Mississippi River. It features a massive 36‑foot wheel. The wheel still grinds grain during live demonstrations. Operated originally by Dr. Edward Turner Bale, this mill reflects early Napa Valley life and agricultural ingenuity. The adjoining 1884 barn, pioneer cemetery, and restored mill pond add depth to the park’s historical tapestry.
