Running 2,610 miles north to south, Chile is the longest country in the world, and 80 percent of it is covered by mountains. With vast wild spaces like 650,000-acre Patagonia National Park (which opened to the public this year), pristine rivers with big trout, classic old-school ski areas, and pisco sours and damn good wine, it’s hard to go wrong. Consider these dream itineraries: (1) Fly into the capital city of Santiago, then work your way south to 370,000-acreYendegaia National Park in Tierra del Fuego. The former cattle ranch opened in 2013, but very few people have been lucky enough to explore this swath of untouched glaciers and peaks. Be one of the first to take it all in on a 16-day boat-assisted hiking and sailing epic withChile Nativo ($8,000). (2) Mid-country, two hours south of Santiago in the Millahue Valley, stay at the brand-new Viña Vik, a 22-room retreat and wine spa in the middle of an 11,000-acre vineyard with stunning views of the Andes (from $1,200). Mountain-bike the 65 miles of vineyard roads, then laze by the infinity pool. (3) Eleven hundred miles north in the Atacama Desert, explore the lunar landscape on horseback, relax poolside at the luxurious Tierra Atacama (from $1,350 for two nights, all-inclusive), then set out after dark to Ahlarkapin Observatory to view the universe through the clearest sky on earth.
