Crossing the Andes on horseback through

the Patos Sur Valley

Calingasta - Province Of San Juan - Argentina

The authentic route of the liberator General José de San Martín to fight the battle of Chacabuco, which allowed the recovery of Chile's independence.

“… We are already in chapel my friend, for our expedition. For this, calculate how my sad and stupid head will be, it is enough to tell you that I need thirteen thousand mules to move..."

Fragment of a letter sent by General San Martín to his friend Tomás Godoy Cruz.
