Calistoga is a city in Napa County, California, United States. The population was 5,155 at the 2010 census.
Calistoga is at the north end of the Napa Valley Calistoga AVA, part of California’s Wine Country. There are numerous wineries within a short drive. The city allows visitors to see wine country as it was before freeways and fast food — only two-lane roads lead there and fast food franchises are banned by law.
Calistoga itself is noted for its hot springs spas such as Calistoga Spa Hot Springs. A local specialty is immersion in hot volcanic ash, known as a mud bath. Nearby attractions include an artificial geothermal geyser known as the “Old Faithful of California” or “Little Old Faithful”. The geyser erupts from the casing of a well drilled in the late 19th century. According to Dr. John Rinehart in his book A Guide to Geyser Gazing, a man had drilled into the geyser in search for water. He had actually “simply opened up a dead geyser”.
Calistoga is home to the Napa Valley Cricket Club who play their games at the Napa County Fairgrounds.
