Between the Andes mountain range, the Amazon rainforest and Patagonia's glaciers, South America lines up landscapes on a continental scale. Distances are considerable, which requires picking one clear travel axis rather than trying to combine everything in a single few-week trip.

Why travel to South America?
The continent holds the world's largest rainforest, its longest mountain range and one of its largest salt deserts, across a territory ten times less densely populated than Europe. Peru and Argentina remain the best-organized gateways for a first circuit.
What to discover in South America?
Peru and the Inca world
Machu Picchu is reached after a 3 to 4-day trek on the Inca Trail, to be booked several months ahead due to the daily visitor quota imposed by Peruvian authorities. Cuzco, the former Inca capital sitting above 3400 meters, requires a day or two of acclimatization before any physical activity. The surrounding Sacred Valley completes the circuit with its markets and pre-Inca agricultural terraces still cultivated today.
Bolivia and the Uyuni salt flat
The world's largest salt desert produces a spectacular mirror effect during rainy season, December to April, when a thin layer of water covers the white surface. The rest of the year, dry season instead reveals the characteristic hexagonal patterns of cracked salt. A 3-day 4x4 circuit generally links Uyuni to the neighboring Chilean Atacama desert, through volcanic landscapes and colorful high-altitude lagoons.
Argentina and Patagonia
Buenos Aires, a city of tango and European architecture, serves as a springboard toward the country's south and the Perito Moreno glacier, one of the world's few glaciers still expanding. El Calafate and El Chaltén hold the region's best hikes, with weather conditions that can change very fast even in the height of southern summer. Budget 15 to 20 days to combine the capital, Mendoza wine country and Patagonia without excessive domestic flights.
The Amazon, across Brazil, Peru and Ecuador
The Amazon rainforest can be reached from several gateways, Manaus in Brazil, Iquitos in Peru or the Napo region in Ecuador, each offering a different way into the river and its wildlife. A 3 to 5-night lodge stay allows spotting pink river dolphins, caimans and exceptional plant biodiversity. High-water season, December to May, eases navigation but reduces some ground-hiking options.
Colombia, a destination on the rise
Cartagena, a fortified colonial city on the Caribbean Sea, and the coffee region around Salento have drawn a growing number of travelers over the past decade. Medellín, long associated with a negative image, has largely transformed and now offers a very dynamic cultural and food scene. Safety has improved markedly in tourist areas, even though some rural regions remain flagged by diplomatic advisories.
Planning a multi-country circuit
Domestic flights are often faster and not necessarily pricier than long-distance buses over great distances, notably between Peru, Bolivia and Argentina. Plan for possible altitude sickness above 3000 meters, with a few acclimatization days built into the schedule before any intense physical activity. A daily budget of 40 to 70 dollars covers a comfortable independent trip outside specific excursions like the Machu Picchu trek.

Frequently asked questions
Do I need to book Machu Picchu far in advance?
Yes, the Inca Trail imposes a strict daily visitor quota and is generally booked 4 to 6 months ahead, especially for a departure in peak season between June and August.
What's the best time to see the Uyuni mirror effect?
Rainy season, December to April, covers the salt surface with a thin layer of water that perfectly reflects the sky, while dry season instead reveals the hexagonal patterns of cracked salt.
Is altitude sickness dangerous in Cuzco or La Paz?
It can cause headaches and nausea in the first days above 3000 meters, but rarely becomes dangerous with gradual acclimatization over 24 to 48 hours, good hydration and light meals.
Can you visit the Amazon without going through Brazil?
Yes, Peru via Iquitos and Ecuador via the Napo region offer equally complete access to the Amazon rainforest, often with jungle lodges considerably more affordable than those found around Manaus.
Is Colombia safe to travel today?
Tourist areas like Cartagena, Medellín and the coffee region are now considered safe, as the security situation has improved markedly over the past decade, even though some isolated rural areas remain flagged.
How long to visit Argentine and Chilean Patagonia?
Budget at least 10 days to combine El Calafate, El Chaltén and Torres del Paine, factoring in sometimes long bus or flight connections between the two sides of the Argentina-Chile border.
Do I need a visa to visit Brazil?
Since April 2025, French citizens once again need an e-visa to enter Brazil, an application to complete online well ahead of departure, unlike the temporary exemption period that preceded it.
What language is spoken across South America?
Spanish dominates in nearly every country, with the notable exception of Brazil, where Portuguese is spoken, making some basics in either language genuinely useful for independent travel across the region's borders.
Can you combine Peru and Bolivia in one trip?
Yes, this is a classic combination via Lake Titicaca, shared between the two countries, with buses or boats connecting Puno on the Peruvian side to Copacabana on the Bolivian side in a few hours.
What budget should I plan for three weeks in South America?
Budget around 1000 to 1500 euros excluding international flights for a comfortable independent trip, adding a specific budget for organized excursions like the Machu Picchu trek or the salt flat circuit.
