Spas have been a long tradition of travelers to the Napa Valley. The hot springs in Calistoga have provided for many spa services, including the popular mud bath.
You can still get a mud bath at a few spas in Calistoga, however most Napa spas provide more traditional spa services like nails, facials, massages and wraps. Of course the wine industry has influenced the spas, which incorporate grape seeds and grape leaves into their various services.
The Napa Valley is a place for a romantic getaway, and a couples massage certainly adds to that ambiance.
