Frequently Asked Questions
What is the absolute best month to drive the Seven Lakes Route?
December, January, and February are generally considered the best months for driving the Seven Lakes Route due to warm weather, minimal rain, and long daylight hours. November and March are also excellent shoulder season options with fewer crowds and beautiful scenery.
Are the roads on the Seven Lakes Route fully paved?
Yes, the main Ruta de los Siete Lagos (RN40) connecting San Martín de los Andes and Villa La Angostura is fully paved. However, some scenic detours, like the old gravel road sections or routes into specific campsites, may still be unpaved.
Do I need a 4x4 vehicle for the Seven Lakes Route?
For the main paved route, a standard 2WD vehicle is perfectly sufficient during spring, summer, and autumn. In winter (May-September), a 4x4 or a 2WD vehicle equipped with winter tires and chains is strongly recommended, and often legally required, due to snow and ice.
What are the daylight hours like in summer and winter on the route?
In summer (December-February), daylight hours are very long, ranging from 15 to 16 hours, allowing for extensive exploration. In winter (June-August), daylight hours are much shorter, around 9-10 hours, significantly limiting your touring time.
What are the road conditions like in winter, and are there any closures?
In winter (May-September), roads can be covered in snow and ice. While the main paved route is usually cleared, conditions can be challenging. Winter tires and/or snow chains are essential and often mandatory. Closures are possible during heavy snowfall, so it's crucial to check local road reports ('estado de rutas') before and during your trip.
Can I visit the Seven Lakes Route during the off-season for budget travel?
Yes, visiting during the off-season (May-September) can be significantly cheaper for accommodations and car rentals. However, be prepared for very cold weather, snow, limited services, and the necessity of a well-equipped vehicle for winter driving conditions. It offers a unique, serene experience for those prepared for the challenges.
How far in advance should I book my car rental for peak season?
For peak season (December-February), it is highly recommended to book your car rental at least 3-6 months in advance. Demand is very high, and prices can increase significantly closer to your travel date, with limited vehicle availability.
