2.South America: Aconcagua, Argentina, 6,961 m (22,838 ft) (32° 39′ 11″ S 70° 00′ 43″ W)High in the Andes near the Argentinean/Chilean border, Aconcagua is the highest peak in the world outside the Himalayas in Asia. A German team was the first to reach its summit in 1897, and it’s been a popular challenge for adventurers ever since. Most climbers fly into Santiago (Chile) or Mendoza (Argentina) and take a bus to Puente del Inca for the normal route or to Penitentes for the Polish Glacier, Polish Traverse and Vacas routes. The so-called “Normal Route” follows Aconcagua’s northwest ridge and is among the world’s highest-altitude non-technical ascents. Still, its considerable elevation means it’s no easy feat, and only an estimated 30% of climbers who attempt to reach the summit are successful.
