December 2026 offers an exceptional window for a road trip across parts of South America, particularly for travellers looking for dramatic landscapes, long summer days and routes that combine mountains, glaciers, forests, vineyards and high-altitude scenery.

As the Southern Hemisphere enters early summer, Patagonia across Chile and Argentina becomes one of the most compelling regions for scenic driving. Argentina’s legendary Ruta 40 also offers an extensive Andes-side journey, while Ecuador’s Avenue of Volcanoes provides a very different road-trip experience through the country’s mountainous interior.

Each route has a distinctive character. Patagonia is built around fjords, glaciers and wilderness, Ruta 40 combines remote landscapes with wine country and national parks, while Ecuador offers volcanoes, indigenous communities and highland scenery.

Why Is December a Good Month for a South American Road Trip?

December marks the beginning of summer in South America, bringing longer daylight hours and generally more favourable driving conditions to several southern destinations.

For Patagonia, the arrival of summer can make remote roads and mountain destinations more accessible while providing extended daylight for long scenic drives.

The season is particularly useful for road-trippers because many Patagonian journeys involve substantial distances between attractions. Longer daylight allows travellers to spend more time exploring without having to compress every excursion into a short window.

In Ecuador, December can provide a relatively drier period in some inter-Andean valleys, although conditions vary by location and altitude.

Why Is Carretera Austral One of Patagonia’s Great Road Trips?

Chile’s Carretera Austral is one of the region’s defining scenic routes, crossing landscapes that demonstrate the extraordinary scale and variety of Chilean Patagonia.

The route passes through areas characterised by fjords, glaciers, temperate rainforests, rivers, mountains and remote wilderness.

December brings early-summer conditions and long daylight hours, creating an attractive environment for travellers planning an extended self-drive adventure.

The route is not simply about reaching a final destination. Much of its appeal lies in the changing scenery along the journey, with forests giving way to mountains, waterways and glacial landscapes.

Travellers should nevertheless plan carefully because sections of the route can be remote, road conditions vary and services may be widely spaced.

What Makes Ruta 40 Special in December?

Argentina’s Ruta 40 offers a contrasting road-trip experience, running broadly parallel to the Andes through some of the country’s most dramatic landscapes.

The legendary highway passes through diverse terrain, including high desert scenery, mountain regions, vineyards and access points to glacial national parks.

December is particularly attractive for a road journey because summer conditions can make many areas more accessible than during colder months.

The route also allows travellers to combine natural attractions with Argentina’s food and wine culture. Depending on the itinerary, a journey along Ruta 40 can incorporate wine regions, historic settlements and spectacular mountain scenery.

Because of the highway’s immense length, however, travellers need to select sections rather than attempting to cover the entire route during a short holiday.

Which Patagonia Experiences Should Road-Trippers Look For?

Patagonia’s attraction lies in its concentration of landscapes rather than one single landmark.

Travellers can encounter glacial lakes, snow-capped mountains, dense forests, fjords and vast open spaces during a single road journey.

In Chile, the Carretera Austral provides access to wilderness areas and dramatic southern scenery. Across the border in Argentina, road trips can incorporate destinations connected with Patagonia’s national parks and glacial landscapes.

December’s longer days make it easier to combine driving with hiking, photography and outdoor excursions.

For travellers interested in nature-focused tourism, Patagonia can therefore function as both a road-trip destination and a base for active outdoor experiences.

Why Should Travellers Consider Ecuador’s Avenue of Volcanoes?

The Avenue of Volcanoes provides a very different road-trip experience from Patagonia.

Located along Ecuador’s mountainous interior, the route is characterised by a succession of dramatic Andean volcanoes, highland landscapes and communities.

December can offer a comparatively favourable period for driving through the inter-Andean valleys, although travellers should still expect changing weather at higher elevations.

The route also offers opportunities to experience Ecuador beyond its natural scenery. Indigenous markets, highland towns and local communities form an important part of the journey.

For travellers who prefer combining landscapes with culture, the Avenue of Volcanoes offers a road trip with a strong human and heritage dimension.

How Does Ecuador Differ From Patagonia?

The contrast between the destinations is one of the strongest reasons to consider both.

Patagonia is associated with expansive wilderness, glaciers, forests, fjords and long-distance driving. The scenery can feel remote and monumental, with journeys often centred on nature and outdoor adventure.

Ecuador’s Avenue of Volcanoes, meanwhile, offers a more concentrated high-altitude journey. Travellers can encounter multiple volcanic peaks within a relatively compact geographical area while moving between communities, markets and historic settlements.

Ruta 40 occupies another position between these concepts, combining Argentina’s Andean landscapes with wine regions, desert terrain and access to major natural attractions.

What Should Travellers Know Before Driving Patagonia?

A Patagonia road trip requires more preparation than a conventional city-to-city driving holiday.

Distances can be substantial, and travellers may encounter long stretches with limited fuel, food, accommodation or mobile connectivity. Weather can also change quickly, particularly in mountainous and exposed areas.

Drivers should check road conditions, vehicle requirements, fuel availability and local weather forecasts before setting out each day.

A suitable vehicle is particularly important on routes where gravel or uneven surfaces occur. Travellers should also avoid assuming that every remote road offers the same services or driving conditions as major urban highways.

Is Ruta 40 Suitable for a Long Road Trip?

Ruta 40 is particularly well suited to travellers who enjoy long-distance driving and flexible itineraries.

Its enormous geographical span means a complete journey requires considerable time, while individual sections can be selected according to available holiday length.

A shorter itinerary can focus on a specific Patagonian or Andean section, allowing travellers to spend more time exploring rather than simply covering kilometres.

December’s summer conditions can make the season attractive, but preparation remains essential because some sections can be remote and road surfaces can vary.

What Makes December 2026 Attractive for Scenic Driving?

The principal advantage of December is the combination of seasonal accessibility and longer daylight across southern destinations.

In Patagonia, early summer opens opportunities for road trips through landscapes that can be difficult to navigate during colder and more challenging periods.

For Ecuador, the inter-Andean valleys can provide a useful driving window while the surrounding highlands remain visually dramatic.

The timing also coincides with the beginning of the Southern Hemisphere summer holiday period, so popular destinations may experience increased demand for accommodation, vehicle hire and attractions.

Travellers should therefore plan important bookings well ahead.

Which South American Road Trip Should You Choose?

The answer depends on the type of journey being sought.

Travellers prioritising glaciers, fjords, forests and remote wilderness can look towards Chilean Patagonia and the Carretera Austral. Those wanting an extended Andes journey combining natural landscapes, vineyards and national parks can consider Argentina’s Ruta 40.

Travellers seeking volcanoes, highland culture and indigenous markets may find Ecuador’s Avenue of Volcanoes more suitable.

All three routes demonstrate why South America can be particularly rewarding for self-drive travel. December 2026 brings summer conditions to the southern part of the continent, creating opportunities to explore vast landscapes at a time when longer daylight hours can make scenic journeys more practical.
