Despite our thirst to discover new wine countries, we'll never abandon our fondness for Napa Valley. Although it's the reigning champ of the American wine scene, it doesn't take its status for granted, and is continually evolving with the development of new inns, restaurants and wineries. Among our favorite contributions to this scenic region is Calistoga Ranch. Set in a secluded canyon, this rustically sophisticated property features a gorgeous spa and 48 individual, cedar guest lodges, all with fireplaces and indoor/outdoor living spaces that take full advantage of the natural setting. Think exclusivity on all counts. The restaurant is open only to guests and owners of the property's few private residences, and a small vineyard offers the opportunity to participate in grape crushing or the bottling and corking of select wines.
