There are three crossings available to continue from San Pedro de Atacama into Argentina. The best is the more northern crossing at Paso de Jama, located approximately 165km southeast of town reached via a road through the Salar de Tara. This part is also a sector of the Reserva Nacional de los Flamencos.

Paso de Sico, slightly more than 200km south of San Pedro, is another alternative reached via a road that runs through Toconao and Socaire.

The third option is further south still at Paso de Socompa, which is reached via a very bumpy road from Pan de Azúcar. Argentina, unlike Bolivia, does not require citizens of the United States to purchase a tourist visa to enter.
