Parque Provincial Aconcagua, Argentina

Parque Provincial Aconcagua is a protected area in the Argentinean Andes, on the Chilean border. It is home to snow-capped Mount Aconcagua, South America’s tallest peak. A trail leads from the park’s entrance to Los Horcones Lagoon and the Durazno Ravine. Huge Andean condors thrive in the high altitude. Nearby is the Puente del Inca, where an orange rock formation makes a natural bridge over Las Cuevas River. © Istock/Guido Martini
