The Andes, stretching across seven countries from Venezuela in the north to Chile and Argentina in the south, is undoubtedly the most famous mountain range in South America. The Andes offer a diverse range of trekking and mountaineering opportunities for both novice hikers and seasoned climbers. The peaks of the Andes stand as pillars of nature, with glaciers, towering rock faces, and stunning alpine lakes surrounding them.
Notable Trekking Routes in the Andes:
- Inca Trail (Peru): One of the most famous hikes in the world, the Inca Trail to Machu Picchu takes trekkers through lush cloud forests, past ancient Inca ruins, and up to the iconic mountaintop citadel. The 4-day trek is moderately challenging and offers a rich cultural experience in addition to the stunning views of the Andean mountains.

The W Trek is a shorter version, taking 5 days to complete, and remains a popular option for trekkers.
Notable Mountaineering Routes in the Andes:
- Mount Aconcagua (Argentina): Standing at 6,961 meters (22,837 feet), Aconcagua is the highest peak in the Western Hemisphere and a popular destination for mountaineers aiming to climb the Seven Summits. The mountain can be summited without technical climbing skills on the Normal Route, but the challenges of high-altitude trekking, extreme weather, and steep terrain should not be underestimated.
- Mount Huascarán (Peru): The highest peak in Peru, Huascarán is a challenging climb that requires technical skills. The summit sits at 6,768 meters (22,205 feet), and mountaineers often face glacial routes, crevasses, and potential avalanche zones.

2. Patagonia: Untamed Beauty and Challenging Climbs
Patagonia, straddling the southern parts of Argentina and Chile, is known for its unspoiled wilderness and challenging terrain. Its glacier-carved valleys, towering peaks, and wind-swept plains provide a perfect stage for mountaineers and trekkers looking to experience some of the most rugged landscapes on Earth.
Popular Hiking Routes in Patagonia:
- Fitz Roy and Laguna de los Tres (Argentina): Mount Fitz Roy is a world-famous peak located in Los Glaciares National Park. The Laguna de los Tres trail is one of the best ways to get up close to the iconic peak, with a challenging but rewarding trek that offers panoramic views of Fitz Roy’s jagged silhouette and the surrounding glaciers.

3. The Amazon and The Andes: Exploring Both Sides of the Continental Divide
South America is not only about towering mountains; the Amazon rainforest also offers its own set of unique adventures. For those looking to combine mountaineering with rainforest exploration, hikes along the eastern slopes of the Andes offer access to both cloud forests and tropical lowlands. These regions are full of biodiversity and provide a striking contrast to the more arid environments of the Atacama Desert or the Patagonian plains.
Notable Hiking Routes:
