Best South American Road Trips for Adventurous Travelers

South America is made for road trips. The continent combines enormous distances with dramatic scenery, remote villages, mountain passes, deserts, rainforests, glaciers, beaches, and some of the most spectacular highways in the world.

For adventurous travelers, driving through South America can be more rewarding than simply flying between major cities. A road trip gives you the freedom to stop at viewpoints, explore places that rarely appear on standard itineraries, and change your plans when an unexpected destination catches your attention.

From the wild landscapes of Patagonia to the high-altitude roads of the Andes, here are some of the best South American road trips to consider.

1. Carretera Austral, Chile

Few road trips in South America feel as remote and adventurous as Chile’s Carretera Austral. The route runs through southern Chile, passing forests, rivers, glaciers, fjords, mountains, and sparsely populated landscapes.

The journey is particularly appealing to travelers who enjoy nature and don’t mind rougher road conditions. Depending on your route and available time, you can explore destinations such as Coyhaique, Cerro Castillo, Puerto Río Tranquilo, and the northern sections of Patagonia.

Why drive it?

• Incredible Patagonian scenery
• Glaciers, lakes, forests, and mountains
• Remote campsites and hiking opportunities
• Excellent opportunities for photography
• A genuine sense of wilderness

Best for: Experienced road trippers, hikers, campers, and wilderness lovers.

2. Ruta 40, Argentina

Argentina’s legendary Ruta 40 is one of the country’s great long-distance adventures. Stretching along the western side of Argentina, the route passes through dramatically different landscapes, including deserts, vineyards, mountains, valleys, and parts of Patagonia.

You don’t have to drive the entire highway to enjoy it. Travelers with limited time can choose individual sections around destinations such as Mendoza, Bariloche, El Chaltén, or El Calafate.

Highlights along the route

• Andean mountain landscapes
• Patagonian scenery
• Wine country around Mendoza
• Mountain towns and national parks
• Long stretches of open road

Best for: Travelers who want a classic, long-distance South American adventure.

3. Patagonia: Argentina and Chile

Instead of following one specific highway, adventurous travelers can create a road trip combining Argentina and Chilean Patagonia.

A possible itinerary could connect destinations such as Bariloche, El Bolsón, Esquel, El Chaltén, El Calafate, Puerto Natales, and Torres del Paine. Border crossings add another layer of adventure, while the scenery changes constantly between the two countries.

This region is particularly rewarding for travelers who enjoy hiking. You can build several days around major trekking destinations and use the vehicle to reach smaller towns, viewpoints, lakes, and trailheads.

Best experiences

• Hiking among dramatic mountains
• Exploring glacial lakes
• Visiting national parks
• Camping beneath wide Patagonian skies
• Driving through remote landscapes

4. Salar de Uyuni and Southwest Bolivia

Bolivia offers some of the most unusual road-trip scenery in South America. The area surrounding the Salar de Uyuni features enormous salt flats, volcanic landscapes, colorful lagoons, deserts, geysers, and high-altitude wilderness.

This is not the easiest road trip for inexperienced drivers. Some routes are remote, navigation can be challenging, and altitude can become a serious consideration. Many travelers therefore explore the region with an experienced local driver or organized 4×4 expedition.

What makes it adventurous?

• Extreme high-altitude landscapes
• Remote desert roads
• Vast salt flats
• Volcanic scenery
• Very limited services in remote areas

Best for: Travelers looking for an expedition rather than a conventional highway holiday.

5. The Trans-Andean Routes in Argentina and Chile

Crossing the Andes by road is one of the great experiences for adventurous travelers. Several routes connect Argentina and Chile, offering dramatic mountain scenery and opportunities to combine cities, wine regions, lakes, and national parks.

One popular option connects Mendoza in Argentina with Santiago in Chile. The journey crosses the Andes and passes through spectacular mountain scenery.

Another option is to explore the Lake District around Bariloche and cross toward Chilean Patagonia.

Mountain weather can change quickly, so travelers should check road and border conditions before setting out.

6. Brazil’s Northeast Coast

South American road trips don’t have to be about mountains and wilderness. Brazil’s northeastern coastline offers a completely different type of adventure.

Travelers can combine coastal cities, fishing communities, beaches, sand dunes, lagoons, and national parks while moving between destinations by road.

Depending on the itinerary, a trip can include places around Bahia, Pernambuco, Alagoas, Ceará, and Rio Grande do Norte.

Why choose Brazil’s coast?

• Beautiful beaches
• Warm tropical weather in many areas
• Colorful coastal communities
• Surfing and water activities
• Excellent opportunities to combine cities and nature

7. The Atacama Desert, Chile

The Atacama Desert is one of the most spectacular environments in South America. A road trip through northern Chile can take you through barren valleys, salt flats, volcanoes, high-altitude lagoons, and landscapes that look almost extraterrestrial.

San Pedro de Atacama is a useful base for exploring the region. From there, travelers can make excursions to destinations such as Valle de la Luna, high-altitude lagoons, and desert viewpoints.

Because some attractions are located at significant elevations and remote locations, preparation is important.

8. The Seven Lakes Route, Argentina

For travelers who want an easier introduction to Patagonia, Argentina’s Seven Lakes Route is an excellent option.

The scenic route connects Villa La Angostura and San Martín de los Andes through the Argentine Lake District. Along the way, you’ll encounter forests, clear lakes, mountain views, and quiet roadside viewpoints.

The route is shorter and more manageable than some of the continent’s major expeditions, making it suitable for travelers who want adventure without committing to weeks on the road.

Ideal activities

• Hiking
• Camping
• Kayaking
• Photography
• Exploring small mountain towns

9. Peru’s Andes by Road

Peru offers some extraordinary high-altitude road journeys. Routes through the Andes can connect destinations such as Cusco, the Sacred Valley, the Colca region, and other mountain communities.

The scenery can change dramatically within a single day, from green valleys to barren mountain passes and high plateaus.

However, mountain driving in Peru requires caution. Roads can be narrow or winding, and altitude can affect travelers who are not acclimatized.

10. The Transamazônica and Amazon Region

For travelers seeking something genuinely remote, parts of Brazil’s Amazon region offer a very different road-trip experience.

The Transamazônica crosses enormous areas of the Brazilian interior, although conditions vary significantly along different sections. Some stretches can be difficult, particularly during rainy periods.

This is not a casual rental-car adventure. Remote travel in the Amazon requires careful planning, appropriate vehicles, local knowledge, sufficient fuel and supplies, and an understanding of seasonal road conditions.

Best for: Highly experienced overland travelers seeking remote environments.

11. Ecuador’s Avenue of the Volcanoes

Ecuador is compact compared with many South American countries, making it attractive for travelers who want dramatic scenery without spending weeks driving between destinations.

A road trip through the Andes can connect Quito with mountain towns, volcanoes, crater lakes, and hiking destinations.

The Avenue of the Volcanoes offers opportunities to see some of Ecuador’s impressive peaks while exploring communities and landscapes along the way.

12. Colombia’s Coffee Region

Colombia’s Coffee Region combines scenic mountain roads with coffee farms, colorful towns, green valleys, and cultural experiences.

A road trip can include destinations such as Salento, Filandia, Armenia, Manizales, and Pereira, depending on the route.

Unlike some remote South American adventures, this region offers plenty of opportunities to stop in towns, visit coffee farms, hike, eat local food, and experience Colombian culture.

How to Plan an Adventurous South American Road Trip

Choose the right vehicle

A normal car may be sufficient for major paved highways, but remote routes can require higher-clearance vehicles or 4x4s. Always research the exact road conditions rather than assuming every route is suitable for an ordinary rental car.

Research border crossings

If your itinerary crosses international borders, check current entry requirements, vehicle rules, insurance requirements, and border operating conditions before departure.

Don’t underestimate distances

South America is enormous. A route that looks short on a map can involve long driving days because of mountains, road conditions, traffic, weather, or border crossings.

Carry emergency supplies

Remote road trips should include sufficient water, food, basic medical supplies, a spare tire, charging equipment, offline maps, and emergency communication options where appropriate.

Check weather and road conditions

Mountain roads, desert routes, and unpaved highways can be heavily affected by weather. Check conditions before leaving and remain flexible enough to change your route when necessary.

Road Trip Tips for First-Time Adventurers

• Download offline maps before entering remote areas.
• Keep some emergency cash available.

Final Thoughts

The best South American road trips are not necessarily the longest ones. What makes them memorable is the combination of freedom, scenery, unexpected stops, and the feeling that you’re moving through landscapes rather than simply checking destinations off a list.

For serious wilderness adventures, Patagonia and the Carretera Austral stand out for their combination of mountains, glaciers, forests, and remote roads. For extreme landscapes, Bolivia’s Uyuni region and Chile’s Atacama Desert offer something completely different. Meanwhile, Colombia’s Coffee Region, Ecuador’s Andes, and Brazil’s northeastern coast provide more accessible alternatives with plenty of culture and variety.

Whichever route you choose, leave room for spontaneity. On a South American road trip, some of the best memories can come from the places you never planned to visit.
