Été in Ruta 40

Été is the only season to drive the full Patagonian stretch of Ruta 40. Argentina's legendary highway offers the best road conditions, longest daylight, and all services open de décembre à février — the ultimate self-drive adventure.

Ruta 40 is Argentina's most legendary highway — stretching over 5,000 kilometers from the Bolivian border to the southern tip of Patagonia, it parallels the Andes through some of South America's most dramatic landscapes. The Patagonian section, from Bariloche in the north to Río Gallegos in the south, is the route's most iconic stretch — a 2,000+ kilometer journey through steppe, mountains, glaciers, and the vast emptiness that defines southern Argentina.

Été from décembre à février is unequivocally the best — and for much of the route, the only practical — time to drive this road. Gravel sections that are impassable in winter become manageable. Services that close from April to November reopen. Fuel stations in remote towns are reliably stocked. And the long daylight hours — up to 17 hours — are essential for covering the vast distances between stops.

The Patagonian Ruta 40 passes through or near an extraordinary roster of destinations: the Lake District (Bariloche, San Martín de los Andes, Villa La Angostura), El Bolsón, Esquel, the remote steppe towns (Gobernador Gregores, Bajo Caracoles), Cueva de las Manos, Los Antiguos, El Chaltén (via spur road), El Calafate, and ultimately Río Gallegos. Each section has its own character, from lush forests to arid steppe to glacial landscapes.

Renting a car in Bariloche or El Calafate and driving Ruta 40 is one of the great road trips on Earth. The Patagonian section can be driven in as little as 5-6 days (rushing), but 10-14 days allows proper exploration of the highlights and side trips. Été guarantees the widest window of good conditions and open services.

Ensoleillement

16-17 hours in the north (Lake District) to 17+ hours in the south, providing ample driving and exploration time.

Weather along Ruta 40 spans multiple climate zones. The northern Lake District section is warmest (24-28°C highs). The central steppe is warm but windy (18-22°C). The southern section near El Calafate is cooler (15-18°C). Be prepared for everything — you'll experience sunny, windy, rainy, and calm conditions all in a single day's drive.

Activites

Activites Disponibles

Epic Road Trip

The core experience — driving one of the world's great highways through constantly changing Patagonian landscapes. The route connects lakes, forests, steppe, glaciers, and frontier towns in a single continuous adventure.

Lake District Driving

The northern section passes through Bariloche, the Seven Lakes Route, and the Andean forest zone. Été offers the best conditions for enjoying the lake-and-volcan scenery.

Steppe Crossing

The remote central section between Esquel and El Calafate is Ruta 40 at its most raw — vast empty steppe, guanaco herds, occasional homesteads, and an overwhelming sense of space.

Side Trip to Cueva de las Manos

Detour from the main route to visit this UNESCO World Heritage rock art site in the Río Pinturas canyon. Été access is best.

El Chaltén Approach

The spur road from Ruta 40 to El Chaltén reveals the stunning Fitz Roy massif gradually as you approach — one of the most dramatic arrivals in Patagonia.

Wildlife Spotting

The steppe sections offer continuous faune sauvage viewing — guanacos, rheas, foxes, armadillos, condors, and eagles are regular companions along the route.

Non Disponible Cette Saison

Some remote gravel sections may be temporarily affected by été stormsA few services and carburant stations operate reduced hours even in été

Hebergement

Ranges from excellent (Bariloche, El Calafate, San Martín) to extremely basic (Bajo Caracoles, Gobernador Gregores). In remote sections, options are limited to one or two basic hotels per town. Camping is possible at many points. Book ahead for January in popular towns. In remote sections, hébergement is first-come-first-served — arrive by early afternoon.

Affluence et Tourisme

The Lake District section is busy en janvier. The remote central section sees scattered road trippers — you might pass 10-20 vehicles per hour or go an hour without seeing anyone. El Calafate is very busy. The mix of crowded and empty is part of Ruta 40's character.

Tarifs

Costs vary enormously along the route. Budget $100-200 USD per day depending on hébergement choices and activities. Car rental for 10-14 days is a significant investment — book well ahead for été. Fuel is expensive in remote areas. The biggest expenses are location de voiture, carburant, and hébergement in popular towns. Remote towns are cheap but limited.

Conditions de Conduite

Important pour les voyageurs en voiture de location

Ruta 40 is increasingly paved, but significant gravel sections remain, particularly in the central steppe between Esquel and El Calafate. Été provides the best gravel conditions — dry and firm. A high-clearance vehicle is strongly recommended; 4x4 is ideal for gravel sections. Essential preparations: spare tire (two if possible), extra carburant container, water, food, and basic tools. Crosswinds are the biggest hazard on exposed sections. Drive defensively on gravel — loose stones, washboard surface, and limited traction. Cell service is absent for long stretches. A voiture de location from Bariloche or El Calafate is the starting point for any Ruta 40 adventure.

Questions Frequentes

What vehicle do I need for Ruta 40?

A high-clearance vehicle is strongly recommended. A 4x4 or SUV is ideal for the gravel sections. A standard car can manage the paved sections but will struggle on rougher gravel. Ensure the vehicle is in excellent condition with good tires. Rent from a reputable agency in Bariloche or El Calafate.

How long does the Patagonian section take?

The driving alone from Bariloche to El Calafate takes about 25-30 hours. At a comfortable pace with stops and side trips, plan 10-14 days. Rushing through in 5-6 days is possible but you'll miss much of what makes the route special.

Is Ruta 40 dangerous?

Not inherently, but it demands respect. The main risks are: route en gravier driving (reduced traction, loose stones), strong crosswinds, vehicle breakdown in remote areas, and fatigue from long distances. Prepare properly, drive at moderate speeds on gravel, and carry emergency supplies.

Can I do Ruta 40 without a car?

Very difficult. Limited bus services connect major towns on the route, but the remote central section has minimal public transport. Hitchhiking is possible in été but unreliable given the sparse traffic. A voiture de location is the practical choice.

What about carburant on remote sections?

Fuel stations exist in all towns along Ruta 40, but distances between them can exceed 300km. Always fill up at every opportunity. Carry an extra carburant container for the most remote sections (Bajo Caracoles to Gobernador Gregores, for example). Été supply is more reliable than shoulder seasons.

Which direction should I drive?

Both directions work. North to south (Bariloche to El Calafate) is most popular, building from the lush Lake District to the dramatic glacier country. South to north works equally well, often with slightly less traffic. Wind is generally westerly, which is a crosswind in both directions.
