Ski Patagonia
A massive urban playground, Nahuhel Huapi (Argentina's first National Park) seems like a massive urban playground, is still wild high country of glacial summits, dense southern beech forests, azure alpine lakes, and wild rivers. Hiking, rock and ice climbing, mountain biking, and whitewater rafting and kayaking are all on the docket. In the winter, you'll find some of the country's best skiing. Go sailing on Lago Nahuel Huapi, the glacial trough that gave the park its name, which can include crossing the Andes to Chile by a combination of boats and buses.

Hike into Chile
In a basin between parallel mountain ranges in Rmo Negro province, about an hour and a half south of Bariloche, the counterculture village of El Bolssn is ideally situated for at least half a dozen great day hikes, including 7,414-foot Cerro Piltriquitron, which offers stunning views of the entire Andean front range that forms the border between Argentina and Chile. Only 20 minutes south is Parque Nacional Lago Puelo, which offers an adventurous, rarely traveled overland route into Chile, while another hour via a smooth paved highway is where to find a cabin built by those two American cowboys.
