More ways to explore the area's outdoor wonders
The road leaves Santiago before dawn and the city lights shrink; by midmorning the Andean massifs dominate the horizon, hulking and patient. You curve through the Intermediate Depression, cross the cordón de Chacabuco tunnel and begin the climb where hairpin turns carve the mountainside. The Aconcagua peak—South America's high crown—throws its white shoulder across the skyline while the Aconcagua River dares you to follow its braided channel downstream.
