Roman Spa Hot Springs Resort in Calistoga delivers the full Calistoga hot spring experience within walking distance of the town's restaurants and shops. The spa draws geothermal water at around 42°C from the Calistoga aquifer for its mineral pools, and blends volcanic ash from nearby sources into the signature mud bath treatments for which the town has been famous since the 19th century. The garden pool complex and indoor spa provide a comfortable base for exploring the northern Napa Valley wine country.
