About Bale Grist Mill State Historic Park
Step back into the 1840s at this remarkably preserved historic site featuring a massive 36-foot water wheel. Visitors can watch the mill in action as it grinds grain into flour, offering a rare glimpse into Napa Valley's agricultural roots before the wine boom. The park serves as a serene educational hub, connecting history buffs and families to the region's pioneer past through live demonstrations and scenic trails.

"I went to the bale grist mill on a camping trip at the bothe napa state park. The hike to the mill from the campground was relatively easy. The hardest part of the hike is the beginning that is steep, but the rest of the hike was mostly flat. The tour of the mill is $8. I highly recommend the tour! It was about an hour long and it was informative and engaging. The tour guide was very nice and answered everyone's questions. Jack at the gift shop was super helpful and knowledgeable about the flour they sell at the mill and shared some homemade bread. If you are traveling in the area I highly recommend checking out the mill!"
