Do you like high altitudes? Then take the route from Mendoza, Argentina to Santiago de Chile via Uspallata (also called Bermejo or La Cumbre) Pass. The road climbs up to 3,800 m (12,500 ft).

The picture above has been taken close the monument of Christ the Redeemer of the Andes, or Cristo Redentor de los Andes (left). If you go there, remember that the monument is accessible only during (southern hemisphere) summer months. (To get to the monument is already quite a thrill.) Also the main road in the pass can be closed during the winter because of snow.
