The Four Seasons Resort Napa Valley isn’t just in the wine country, it’s set on the grounds of a working winery on the fringe of Calistoga, its 85 rooms and suites divided among several low-slung buildings scattered amid oak trees and vineyards. The accommodations are typically luxe, and the style is modernist with a NorCal farmhouse accent. There’s an expansive spa with an outdoor garden and an adults-only swimming pool, and bikes are available for exploring the countryside. Auro, the hotel’s fine dining restaurant, has been recognized with one MICHELIN Star.
