Road Conditions by Season

Summer (Dec - Mar)

Roads are generally excellent, paved, and dry. Expect clear skies and pleasant temperatures. Winds can be strong, especially in the open sections. Watch for occasional livestock (sheep, cows) on road shoulders.

Winter (Jun - Sep)

While this route is primarily paved, winter (June-September) can bring snow and ice, especially during cold snaps. Roads are usually cleared quickly, but vehicles should be equipped with winter tires or chains if conditions are severe. Drive with caution and check local road reports before departing.

Year-round Notes

This is a well-maintained, fully paved route. The primary year-round considerations are the strong Patagonian winds, which can affect vehicle stability, and the occasional presence of free-roaming livestock, particularly on road shoulders. Always be alert, regardless of the season.

Vehicle Recommendation

For this entirely paved and relatively short route, a standard 2WD sedan is perfectly adequate. While an SUV or 4x4 offers more comfort and clearance for exploring unpaved side roads, it's not essential for the main San Martín to Junín de los Andes connection.

Essential Driving Tips

  • 1Keep headlights on, even during the day, as it's a legal requirement in Argentina.
  • 2Be prepared for sudden strong Patagonian winds, especially on open stretches. Grip the steering wheel firmly.
  • 3Watch for livestock (sheep, cows, horses) on or near the road, particularly around Mapuche communities. They have right of way.
  • 4Ensure your fuel tank is at least half full before departing San Martín, though Junín has ample refueling options.
  • 5Carry a physical map or download offline maps, as cell signal can be intermittent in some areas.
  • 6Respect local Mapuche communities; if stopping at roadside stalls, engage respectfully.
  • 7Allow extra time for photo stops – the views of Lanín and the Chimehuin are spectacular.
