On the way back from Chile to Argentina, after crossing the Andes mountains and when there are only some hills left, you'll find this magnificent view as you cross the river Blanco, in the Potrerillos town.
I've crossed the Andes mountains range three times in the past and never stopped to visit this natural wonder called Puente del Inca or Inca Bridge located a few miles away from the Aconcagua foot. This time I did it.
