Calistoga, in the Upper Napa Valley, is most famous for Old Faithful, the geyser of hot water and steam that erupts every half hour. But it’s also popular with Bay Area residents for their mud baths and mineral pools, which are said to rejuvenate the mind and the body.

The oldest spa in town, Indian Springs, has an Olympic-sized mineral pool, which is heated by the steam rising from the property’s 230-degree geysers, which means a 102-degree pool in the winter. Combine the pool with a mudbath treatment to get the full Calistoga experience. Other spas to consider include Dr. Wilkinson’s Hot Springs Resort, which also offers accommodations in small cottages, or Golden Haven Hot Springs, which specializes in his and hers mud bath tubs for a romantic soaking in peat moss and volcanic ash. While you’re in Calistoga, you might want to bike or walk to a winery for a tour--try Sterling Vineyards, which is perched 300 feet above the town; every tour of the vineyard includes an aerial tram ride to the winery on top of the mountain.
