Driving the legendary Route 40 in Argentina: Road Trip Guide

Get ready for an epic adventure down Argentina's Ruta 40! This legendary highway stretches over 5,000 km (3,107 miles) from the southern Santa Cruz Province all the way north to Jujuy, hugging the Andes mountains the entire way. Locals call it Ruta Nacional 40, RN 40, Ruta 40, or simply La Cuarenta.

You'll be cruising through some seriously remote areas, especially in the south where you might find yourself with 200km stretches of nothing but you and the open road. Keep an eye out for the amazing scenery as you pass through 18 national parks and over 27 Andean passes.

Starting near sea level at Cabo Vírgenes (Cape Virgins) in Patagonia, the road climbs to a staggering 4,956m (16,259ft) at Abra del Acay in Salta! Along the way, you'll witness everything from Patagonian plains and pristine lakes to bustling cities, volcanic lava fields, ancient forests, and shimmering salt flats. Some parts of the route, especially during winter, can be blocked by ice and snow. The highest town in Argentina, Mina Pirquitas, also lies on Ruta 40, sitting pretty at 4,271m (14,003ft).

Plan for at least 10 days to two weeks to really soak it all in. Don't miss the chance to see Fitzroy and Cerro Torres near El Chalten in Patagonia. Other highlights include Cueva de las Manos with its ancient cave art, Los Glaciares National Park, and the Calchaquí Valleys.

Be warned, though: this isn't a Sunday drive. While much of Ruta 40 is paved, some southern sections are unpaved and can be rough, with strong crosswinds and gravel roads that demand extra caution. You might need a 4x4 for some stretches. Cell service is spotty outside towns, so pack plenty of food, water, and repair equipment. Gas stations can be far apart, so fill up whenever you get the chance.

Ruta 40 is more than just a road; it's an unforgettable journey through the heart of Argentina.
