Full guide to Ruta 40 →

Ruta 40, Argentina's iconic highway stretching over 5,000 kilometers from the Bolivian border to Cabo Vírgenes at the tip of Patagonia, is one of the world's great road trips. The Patagonian section, from Bariloche in the Lake District south to Río Gallegos, traverses some of the most spectacular and remote landscapes on Earth. In winter, from June to August, this journey becomes an extreme adventure. The northern Lake District section passes through snow-covered forests with views of volcanic peaks and frozen lakes. The central stretch crosses the vast Patagonian steppe — an endless expanse of wind-blown grassland where guanacos, rheas, and condors are the only company for hundreds of kilometers. The southern section connects the glaciers near El Calafate with the windswept coast. Winter conditions on Ruta 40 are serious: long sections of gravel road may be icy or snow-covered, services are sparse to nonexistent between widely spaced towns, and the wind is relentless. Yet for prepared drivers with a well-equipped vehicle, winter on Ruta 40 offers an experience of Patagonia at its most raw and magnificent. The solitude is complete, the landscapes are transformed by snow and frost, and the sense of adventure is unmatched. This is not a casual drive — it requires planning, preparation, and respect for the conditions — but for those who undertake it, winter on Ruta 40 becomes a life-defining journey.

Weather Overview

Avg High

5°C

Avg Low

-5°C

Precipitation

Varies dramatically by section. Western sections near the Andes receive more snow and rain. The central steppe is drier but colder. Snow, ice, and frost are common throughout.

Wind

Constant and powerful westerly winds across the steppe, regularly exceeding 80 km/h. Wind is the single greatest driving hazard.

Daylight

Approximately 8-9 hours depending on latitude. Short days mean limited driving time.

Winter conditions on Ruta 40 vary from heavy snow in the Andes foothills to dry, bitter cold on the steppe. The one constant is wind. Temperatures can drop well below -10°C at night in central sections. The route passes through multiple climate zones, and weather can change rapidly.

Activities

Available Activities

Epic Road Trip

The journey itself is the activity — driving through some of the most spectacular and remote landscapes in the Americas, with winter adding drama and challenge.

Wildlife Spotting

Guanacos, rheas, foxes, and condors inhabit the steppe and can be spotted along the route. Winter's sparse vegetation makes sightings easier.

Photography

Winter light on the steppe creates extraordinary photography opportunities — vast skies, frost-covered landscapes, and the dramatic Andes backdrop.

Town Stops

Small towns along the route (Perito Moreno, Bajo Caracoles, Gobernador Gregores, Tres Lagos) provide fuel, meals, and fascinating encounters with isolated communities.

Lake District Skiing

The northern section near Bariloche and Villa La Angostura connects to ski resorts, combining the road trip with winter sports.

Not Available This Season

Most roadside campgroundsSummer hiking trails accessed from the routeSome fuel stations in very remote sectionsGravel sections may be officially closed after heavy snow

Accommodation

Accommodation along Ruta 40 is sparse and basic, with small hotels and hostels in the widely-spaced towns. In winter, some close entirely. Always confirm availability before setting out for the next stop. Towns like Perito Moreno, Gobernador Gregores, and Tres Lagos have a few options. El Calafate and Bariloche at either end have full services.

Crowds & Tourism

You may drive for hours without seeing another vehicle. Ruta 40 in winter is one of the emptiest roads imaginable. The solitude is absolute and is both the appeal and the danger.

Pricing

Fuel is the main expense and is significantly more expensive in remote sections. Carry extra fuel as stations are far apart and some close in winter. Accommodation is affordable but limited. Car rental for this trip should be arranged in Bariloche or El Calafate, and you'll need a vehicle rated for the conditions.

Driving Conditions

Important for car rental travelers

Winter driving on Ruta 40 is a serious undertaking. Many sections remain unpaved gravel, which becomes icy and treacherous in winter. Snow chains are absolutely essential. Ice, snow, and mud can make sections impassable. The wind is a constant danger, capable of pushing vehicles off the road. Fuel stations are hundreds of kilometers apart — always fill up and carry reserves. Carry emergency supplies: food, water, warm clothing, blankets, a satellite communicator, and tools. Inform someone of your route and expected arrival times. A 4WD vehicle in excellent condition is strongly recommended. Check road conditions with Vialidad Nacional before each segment.
