Tour the Historic Mill at Bale Grist Mill State Historic Park

The historic mill inside Bale Grist Mill State Historic Park was originally built in 1846. At that time Dr. Edward Turner Bale owned the mill, having received a land grant from the Mexican government. The mill remained an important part of the Napa Valley settlement area from about 1850 until the early 1900s during which time locals would bring their wheat, corn, oats, and barley to be ground here.

Today this fully restored water powered grist mill is operated by the Napa Open Space District. Exhibits of late 1800 tools and millstones are on display inside the mill. Milling demonstrations and guided tours are available only on the weekends; community events are held onsite throughout the year.
