Crossing the Andes on horseback through Patos Sur Valley

Calingasta - San Juan - Argentina

Embark on the legendary trail of General José de San Martín, the hero who led the battle of Chacabuco and paved the way for the recovery of Chile 's independence. Follow in the footsteps of the liberator and discover the historic path that shaped a nation’s destiny.

"… we are already in chapel, my friend, for our expedition. To estimate how my sad and stupid head works, I tell you that I need thirteen thousand mules to move myself…"

*Note: This is a humorous and exaggerated expression used by San Martín to convey the complexity and difficulty of their undertaking. Mulases were used as pack animals in the Andes, so San Martín is implying that he needs an absurdly large number of them to accomplish their goal.

What makes this experience so memorable?
