There’s always a hot time in the old town of Calistoga (Chamber of Commerce +1 707 942 6333). Its thermal springs have been drawing travelers since 1859, when California’s firstmillionaire, colorful Sam Brannan, opened a mineral spa for wealthy San Franciscans. The story goes that he intended to promote hisenterprise as the “Saratoga of California,” but at a banquet he imbibed a bit of the bubbly before his speech and the phrase came out “Calistoga of Sarafornia.” It’s easy to picture the resort through some remarkable dioramas, made by a Disney artist, at the Sharpsteen Museum (1311 Washington St. +1 707 942 5911), which also has an original furnished cottage.People still visit Calistoga spas to soak in hot mineral water or in vats of volcanic mud, said to be therapeutic. You have your choice of manyspas around town, including Calistoga Spa Hot Springs (1006 Washington St. +1 707 942 6269. Fee).
Only three geysers in the world erupt on a handy schedule—in Yellowstone National Park, in New Zealand, and near Calistoga. Just outsidetown, the Old Faithful Geyser of California (1299 Tubbs Ln. +1 707 942 6463. Adm. fee) shoots a blast of water 60 to 80 feet [18 to 24 meters] high every 40 minutes on average. The water is 350ºF [177ºC], and the sulfur smells like rotten eggs.
