Calistoga

Calistoga is a small city in California's Napa Valley. It's known for hot springs, mud baths and wineries, including one set in Castello di Amorosa, a medieval-style castle. The Old Faithful Geyser of California erupts at regular intervals. Works by Italian artist Carlo Marchiori are displayed at the Ca'toga Galleria D'Arte, in town. To the southeast, Bale Grist Mill State Historic Park has an 1846 mill.
