St. Helena
A working 1840s water-powered grist mill on a wooded creekside site just north of St. Helena, now a state historic park operated by the Napa County Regional Park & Open Space District with the Napa Valley State Parks Association. Weekend visitors can watch the miller grind grain, buy stone-ground flour and picnic at tables around the mill.
