10 Best Treks in South America You Haven't Heard Of (2026)

Everyone knows the Inca Trail and the W Trek. But South America has dozens of spectacular routes that are less crowded, often cheaper, and every bit as stunning. These ten range from rainforest granite to the southernmost trail on Earth — a mix of what to do after you've ticked the classics.

1. Cochamó Valley, Chile

The "Yosemite of South America" — granite domes over Valdivian rainforest. ~2–7 days, moderate–hard, best Dec–Mar. Wild, road-free and climber-famous.

2. Cerro Castillo, Chile

The quiet alternative to Torres del Paine, in Aysén. 4 days, hard, best Dec–Mar. Scree passes and a turquoise glacial lagoon, with a fraction of the crowds.

3. Huemul Circuit, Argentina

El Chaltén's technical loop — Tyrolean rope crossings and a jaw-dropping view of the Southern Patagonian Ice Field. 4 days, advanced, Dec–Mar.

4. Dientes de Navarino, Chile

The world's southernmost trek, on Isla Navarino below Ushuaia. ~4–5 days, hard, Dec–Mar. Raw, remote sub-Antarctic terrain.

5. Choquequirao, Peru

The "other Machu Picchu," reachable only on foot — and almost empty. ~4–5 days, hard (big canyon descents/climbs), best Apr–Oct.

6. Cordillera Huayhuash, Peru

Many trekkers' pick for the most spectacular range in the Andes. ~8–10 days, hard, high altitude, best Jun–Aug.

7. Chapada Diamantina, Brazil

Table mountains, caves and waterfalls in Bahia. Multi-day options, moderate, best Apr–Oct. A different face of Brazil.

8. Sacred Valley by Mountain Bike, Peru

Singletrack and dirt roads between Inca ruins above Cusco. 1–3 days, moderate, best Apr–Oct. Acclimatize first.

9. Volcán Lanín Traverse, Argentina–Chile

A cross-border volcano objective on skis or foot. Multi-day, advanced, season depends on mode. Big, wild and quiet.

10. Quebrada de Humahuaca, Argentina

High-altiplano color, culture and canyon walks in Jujuy. Flexible days, moderate, best Apr–Nov.

Which Should You Choose?

For granite and glaciers: Cochamó or the Huemul Circuit. For Inca ruins without crowds: Choquequirao. For high-altitude drama: the Cordillera Huayhuash.
