Spread across the feet of the Andes, this is the narrowest wine-growing valley with the steepest slopes, offering visitors one of the most stunning wine country tours in terms of scenery. The Aconcagua is characterized by winter rains and cool breezes entering from the Pacific Ocean, and is particularly well adapted for growing syrah, or blends based on syrah. The Aconcagua is ideal for visitors headed to Argentina or skiers visiting Portillo or Ski Arpa resorts, and there is a spa and lots of picturesque rural adobe architecture. Beyond the restaurants in this area, note that the Portillo resort is open year-round for lunch, and is worth the extra 1 1/2-hour round-trip drive from Los Andes for its majestic Alpine views.
