Autumn in Ruta 40

Autumn on Ruta 40 is the ultimate Patagonian road trip. Argentina's legendary highway stretches past golden steppe, fiery Lake District forests, and snow-dusted Andes peaks on roads you'll have almost entirely to yourself.

Ruta 40, Argentina's iconic highway running over 5,000km along the Andes from Cabo Vírgenes in the south to the Bolivian border, is one of the world's great road trips. The Patagonian section, from Río Gallegos to Bariloche and beyond, is particularly spectacular. During autumn, from March to May, this legendary route offers what may be its finest driving experience.

In the north, around the Lake District, autumn transforms the roadside forests into corridors of fire — the Seven Lakes Route between San Martín de los Andes and Villa La Angostura is considered one of Argentina's most beautiful autumn drives. Further south, the steppe sections between El Calafate and El Chaltén take on golden-brown hues under vast Patagonian skies, with the Andes providing a constant western backdrop.

Autumn is arguably the best season for driving Ruta 40. The summer tourist traffic has subsided, leaving the road remarkably empty. Temperatures are comfortable for driving, and the autumn light — low and golden — transforms the landscape into a photographer's paradise. The reduced services along remote sections require careful planning, but the freedom of having one of the world's most scenic highways to yourself is unmatched. Self-driving Ruta 40 in autumn is the quintessential Patagonian adventure.

Activities

Available Activities

Seven Lakes Route (Ruta de los Siete Lagos)

The stretch between San Martín de los Andes and Villa La Angostura passes seven glacial lakes framed by forests ablaze in autumn colors. This is arguably the most beautiful section of Ruta 40 in autumn.

El Calafate to El Chaltén Scenic Drive

Drive through vast Patagonian steppe with the Fitz Roy massif gradually appearing on the horizon. Autumn's clear skies often provide the best mountain visibility of the year.

Estancia Stops Along the Route

Traditional estancias along Ruta 40 welcome road-trippers for lamb asados, horseback riding, and overnight stays. Autumn's quieter roads make these stops more relaxed and personal.

Lake District Town Hopping

Use Ruta 40 to connect Bariloche, Villa La Angostura, San Martín de los Andes, and Junín de los Andes, each offering unique autumn character, craft beer, chocolate, and mountain culture.

Photography Expedition

Autumn light on Ruta 40 is extraordinary — golden steppe, fiery forests, snow-capped peaks, and empty roads create endless composition opportunities at every turn.

Not Available This Season

Some southern gravel sections may be impassable after snow or heavy rainRemote fuel stations may have limited hours or close for seasonMountain passes may close temporarily due to snow in MaySome roadside services and campgrounds close after Easter

Accommodation

Accommodation varies dramatically along the route. Lake District towns offer abundant options. Remote steppe sections between El Calafate and the Lake District have very few options — mainly small towns like Gobernador Gregores and Perito Moreno. Book ahead and confirm operations in autumn, as some places close for the season.

Crowds & Tourism

Autumn traffic on Ruta 40 is minimal. The summer tourist convoys are gone, and you may drive for hours without seeing another vehicle on southern steppe sections. Lake District sections see more traffic but are still pleasantly quiet. This emptiness is one of autumn's greatest gifts.

Pricing

Autumn offers good value along the route. Accommodation in Lake District towns drops significantly from summer peaks. Fuel costs are the main expense, and prices increase in remote areas. Plan fuel stops carefully as prices and availability vary. Car rental from major cities (Bariloche, El Calafate, or Buenos Aires) is well-priced in the shoulder season.

Driving Conditions

Important for car rental travelers

Ruta 40 conditions vary enormously. The Lake District section is mostly paved and excellent. Southern sections include long stretches of gravel (ripio) that require careful driving at reduced speeds. Strong crosswinds on the steppe demand two hands on the wheel at all times. Fuel stations are very sparse between El Calafate and the Lake District — carry extra fuel and plan stops meticulously. A high-clearance vehicle is recommended for the full route; 4x4 adds security on gravel sections. Always carry emergency supplies, water, food, and warm clothing. Cell coverage is nonexistent on long stretches.

Packing Essentials

Sunglasses for steppe glare
Extra fuel container
Water and food supplies for remote stretches

Frequently Asked Questions

What's the best section of Ruta 40 for autumn driving?

The Seven Lakes Route between San Martín de los Andes and Villa La Angostura offers the most spectacular autumn scenery. The El Calafate to El Chaltén stretch provides dramatic mountain views. The combination of both sections makes an ideal autumn road trip.

How long does the Patagonian Ruta 40 take to drive?

From Bariloche to El Calafate via Ruta 40 takes a minimum of 3-4 days at a rushed pace, but 7-10 days is recommended to enjoy the scenery, side trips, and small towns. From Río Gallegos to Bariloche, add 1-2 more days.

Do I need a 4x4?

A high-clearance vehicle is strongly recommended for the full route due to gravel sections. A 4x4 provides added security, especially on remote stretches and in wet conditions. The Lake District sections are fine with a standard car on paved roads.

How do I handle fuel on remote sections?

Plan fuel stops meticulously. Fill up at every opportunity, even if your tank isn't empty. Carry an extra fuel container for the remotest sections (between El Chaltén and Perito Moreno town, for example). Fuel prices increase in remote areas.

Is Ruta 40 safe in autumn?

Yes, the route is safe but requires preparation. The main risks are mechanical issues in remote areas, running out of fuel, strong crosswinds, and rapidly changing weather. Drive during daylight hours, carry emergency supplies, and inform someone of your route. Cell coverage is spotty to nonexistent on remote stretches.

Where should I rent a car for Ruta 40?

Bariloche and El Calafate are the most popular pickup points. Some agencies allow one-way rentals between cities (with a drop-off fee). Book a high-clearance vehicle and check if the rental agreement covers gravel road driving.
