Argentina: Aconcagua Provincial Park
Aconcagua PP protects the tallest mountain peak on the South American continent – Mount Aconcagua with a summit elevation of 6,961 m (22,838 ft). The mountain was first climbed in 1897 and the ascent is difficult in terms of elevation and wind but relatively straightforward in terms of terrain. On a clear day (and we got super lucky), the park offers an absolutely stunning panorama of the Andes and the snow and glacier cover Aconcagua. Several hiking trails take you even further toward the foundation of the mountain range with even more superb views. Another attraction is a picturesque Horcones Lagoon, a great spot to see rare birds and some of the local fauna.
