Calistoga is less than two hours from all 3 of Northern California’s Major International Airports: San Francisco International (SFO), Oakland International (OAK), and Sacramento International (SMF), and only 45 minutes from a major regional airport—Santa Rosa (STS).
Websites for all four regional airports are listed below and have complete information regarding ground transporation, rental cars, and much more.
If you don’t want to rent a car at the airport, you can get ground transporation from San Francisco or Oakland to Napa, and either rent a car in Napa, or take the VINE up to Calistoga.
