Auberge du Soleil
This 50-room, adults-only luxury inn is one of the most exclusive (and expensive) destinations in California wine country. Despite its intimate size, it has all the amenities of a larger resort: a 7,000-square-foot luxury spa, a lovely pool, and a Michelin-starred restaurant. Views of the surrounding countryside are phenomenal, the olive-grove grounds are lush and peaceful, and the homey rooms all come with huge terraces (and, in most, fireplaces and soaking tubs). It's a truly special, romantic retreat, and its location in Rutherford is convenient for exploring Napa Valley (as is the free Mercedes Benz drive program).
