Would you like to live an unforgettable experience in the Andes? Go from Mendoza in Argentina to Santiago de Chile on this 7-day trek and cross the range through a historical pass.

On this program, I invite you to cross the Andes through the Portillo Piuquenes Pass, a historical site used by the Army of the Andes to liberate Chile in 1816.

Take a look at the itinerary below to see what we will do each day of the trip.

Although this expedition is not technically difficult, keep in mind that it is physically demanding, so it is very important to have a good level of fitness.
