Ruta 40 (Argentina)

Ruta 40 is the longest road in Argentina at 3,227 miles, running from the Bolivian border to Tierra del Fuego along the spine of the Andes. The section through Patagonia — from Bariloche south to El Calafate — is the driving experience of a lifetime: vast, empty steppe with snow-capped peaks in every direction, no traffic, no speed cameras, and roads that stretch to the horizon. Some sections are still unpaved gravel, adding an expedition quality that paved roads can't replicate. It's not about corners or speed — it's about the overwhelming scale of landscape and the freedom of the open road.
