Having landed in Bariloche, you can explore the park on an organized tour or on your own. Nearby excursions such as the Circuito Chico, Circuito Grande, a trip to Tronadór, or the ski area at Catedral can be done in a day. Since much of the park is covered by Nahuel Huapi Lake (it's 96 km long, covering 346 square mi), some of your exploration will be by boat to islands, down narrow fjords, or to distant shores on organized excursions. Small towns like Villa La Angostura and Villa Trafúl are excellent destinations for further explorations on foot or by horse to smaller lakes with their connecting streams, waterfalls, and surrounding forests and high peaks. Since most of the park is at a low elevation (under 6,000 feet), getting around in winter is not difficult—just cold. Fall foliage, long, warm summer days, and spring flowers are the rewards of other seasons. Park entry is 12 pesos.
