Calistoga is at the north end of the Napa Valley in the Bay Area region of California. Calistoga was founded as a hot springs resort in the 1860's by Sam Brannan, California's first millionaire, and has long been a destination for its natural hot springs and mineral water and their supposed health benefits. Its position at the north end of the Napa Valley also makes it a gateway to Sonoma County wine country. Calistoga is a visitor's destination that celebrates being different - franchise fast food is against the law really! and healthy hedonists are celebrated. Go wine tasting, have a fabulous dinner, then take a bike ride and have a mud bath before you leave.
