Ruta de los Seismiles

The Ruta de los Seismiles threads through the Puna de Atacama at altitudes that’ll leave you gasping, connecting Argentina’s collection of volcanic peaks above 6,000 meters. This remote route runs from Fiambalá through the Antofagasta de la Sierra region, passing beneath giants like Ojos del Salado (6,893m) and Incahuasi (6,621m). The track crosses endless salt flats, volcanic debris fields, and ancient lava flows where the only company you’ll find are vicuñas and the occasional mining truck.

This is expert-level terrain demanding high-clearance 4WD, spare tires, and serious altitude preparation — you’re spending days above 4,000 meters. Sharp volcanic rock punctures tires without warning, weather changes from scorching days to freezing nights in minutes, and the nearest help is hundreds of kilometers away. Best tackled April through October when storms are less likely. Bring extra fuel, water for a week, and respect for one of South America’s most unforgiving landscapes. The payoff: standing beneath the tallest volcanoes in the world with nothing but silence and endless sky.
