Overview
The Napa County Regional Park and Open Space District and the Napa Valley State Parks Association took over operation of Bothe-Napa Valley State Park and the adjacent Bale Grist Mill State Historic Park on April 1, 2012. No State services or staff are available.
Bale Grist Mill State Historic Park is the site of a water-powered grist mill that was built in 1846 by pioneer doctor, Edward Turner Bale. The mill and its 36-foot water wheel have been partially restored, and an adjacent museum tells the story of the site. The park is three miles north of St. Helena (3369 N St.) on Highway 29.
