It's no wonder royalty, A-list celebrities, and athletes keep returning to the luxury Calistoga Ranch: It's in a class all by itself. Guests rent exquisite private lodges, set on a private 157-acre park-like property complete with hiking trails and a top-of-the-line restaurant and spa. Attention to detail carries over from room design to landscape planning -- all modules for the lodges were flown in by helicopter to minimize impact on surrounding trees and to maximize privacy. The property boasts plenty of activities, including outdoor yoga, a beautiful heated outdoor pool, a bocce court, a fabulous fitness center, and wine tasting seminars. If guests decide to venture out for some reason, they can easily access downtown Calistoga and other towns with not only loaner bikes, but loaner Mercedes-Benzes! This property stands out as one of the most remarkable not just in Napa Valley but in the entire country.
