The trail for this route begins in a small seating in the Nº 7 route that connects Argentina and Chile, approximately at 166 kilometers from the city of Mendoza.

From Punta de Vacas walk on the left side of the Vacas River until you reach the primitive Las Leñas refuge. Las Leñas is where the Aconcagua Provincial Park rangers hand out litter bags and check the permits. The approach takes 3 days to Plaza Argentina which is the base camp of this route. The first day of walk is to Las Leñas refuge, the second day of walk is to Casa de Piedra and the third day you reach Plaza Argentina.

Depending on the amount of snow in the winter it might be necessary to cross the Vacas river here. It is better to cross the river a little bit lower from where the refuge is, where the river is wider and less deeper. Continue walking along the Vacas River until you reach the Casa de Piedra refuge located on the west bank of the river directly opposite of the Relincho Valley.

The Relinchos begins as a narrow and steep canyon with a good trail on the north side. It might be necessary to cross a couple of times the relincho stream before leaving the Superior Valley. Keep to the south side of the stream until you reach the walls that mark Plaza Argentina.
