The best treks in South America in 2026 are Peru's Ausangate Trek (a 70 km high-altitude circuit reaching 5,200 m), Patagonia's Vuelta al Huemul (a wild 67 km loop with ice-field views) and Colombia's Lost City Walking Track (a 44 km jungle route to a pre-Columbian city). Together they span glaciers, high Andes and rainforest.
What are the best treks in South America?
South America packs the planet's longest mountain chain, the Andes, into routes that range from sweltering jungle to glacial Patagonia. The continent rewards trekkers who want altitude, solitude and culture in one trip. The six routes below cover Peru, Argentina and Colombia, and each links to a full HikeLoad route guide with GPX. Three stand out as the must-do circuits, and the rest round out a continent-wide shortlist for 2026.
Unlike Europe's hut-to-hut comfort, most South American treks are camping-based and remote, so self-reliance and a warm sleep system matter more than on a teahouse trail. Acclimatisation is the other constant: many routes climb above 4,500 m within a day or two of the trailhead.
What is the best high-altitude trek in Peru?
The Ausangate Trek is Peru's finest high-altitude circuit, looping roughly 70 km around the glaciated 6,384 m Nevado Ausangate over 5–6 days. You cross passes near 5,200 m, camp beside turquoise glacial lakes and pass the multicoloured slopes of Vinicunca, the Rainbow Mountain, at 5,036 m, all without the permit lottery of the Inca Trail. Nights at the 4,500–4,800 m camps drop below −10 °C even in the dry season, so a warm bag and a tough pack are essential; carry layers and water in a durable 35 L daypack like the Patagonia Ascensionist 35L while horses haul the camping load. For a gentler Peru option, our Salkantay Trek guide reaches Machu Picchu without the crowds.
What is the best trek in Patagonia?
For experienced trekkers, the Vuelta al Huemul near El Chaltén in Argentina is Patagonia's wildest accessible loop: about 67 km over 4 days, with two Tyrolean rope traverses across glacial rivers and a grandstand view over the Southern Patagonian Ice Field and the Viedma Glacier. It is a self-supported, weather-exposed circuit where Patagonian wind can pin you down for hours, so you carry everything in a full-size pack such as the Gregory Baltoro 75 or a lighter Osprey Atmos AG 65 if you pack disciplined. The season runs November to March, the southern summer.
What is the best jungle trek in South America?
The Lost City Walking Track (Ciudad Perdida) in Colombia's Sierra Nevada de Santa Marta is the continent's standout jungle trek: a 44 km round trip over 4 days to the 1,200-year-old terraced city of Teyuna, built centuries before Machu Picchu. It is hot and humid rather than high, with river crossings and steep mud, so the challenge is heat management and footing, not altitude. It is best in the drier window from December to March.
South America trek comparison
| Trek | Country | Distance | Best season |
|---|---|---|---|
| Ausangate | Peru | 70 km | May–Sep |
| Vuelta al Huemul | Argentina | 67 km | Nov–Mar |
| Lost City | Colombia | 44 km | Dec–Mar |
| Salkantay | Peru | 74 km | May–Sep |
When is the best time to trek in South America?
Timing depends on region, because the continent crosses the equator and the southern hemisphere seasons. Peru's Andean dry season runs May to September, the best window for Ausangate and Salkantay. Patagonia's trekking season is the southern summer, November to March, when the Vuelta al Huemul is passable. Colombia's Caribbean Sierra Nevada is drier and safer from December to March. Cross-hemisphere planning means South America offers a quality trek in almost any month of 2026, as long as you match the route to the calendar. Park and access rules for Peru are managed by SERNANP, and Argentina's Los Glaciares region is detailed by Argentina's national parks service.
What gear do South American treks need?
Because most routes are camping-based and cold at altitude, prioritise a four-season-capable sleep system and a pack sized for self-support. A 50–65 L carrier covers the high Andes circuits, while the warmest nights on Ausangate and the Vuelta al Huemul justify a dedicated down sleeping bag rated below −10 °C. Build your clothing around the four-layer mountain layering system, since Andes weather swings from intense UV at midday to hard frost overnight.
How much do South America treks cost in 2026?
South America offers strong value compared with the Himalaya. A guided 5–6 day Ausangate Trek from Cusco costs 350–600 USD in 2026, including transport, tents, meals and an arriero with pack horses. Colombia's Lost City is similar at 350–550 USD for the mandatory 4-day guided trip, a price fixed across operators to protect the indigenous-managed site. Patagonia's Vuelta al Huemul is the cheapest in guiding terms because it is self-supported and permit-light, but you must own or rent a full camping kit, and El Chaltén's remoteness raises travel costs.
Across all three, the main expenses are international flights and the gear you bring rather than the trek fee itself. Investing in your own warm sleeping bag and a durable pack pays off over rentals; the Gregory Baltoro 65 handles self-supported loads on the Vuelta al Huemul, while a lighter Patagonia Ascensionist 35L covers guided trips where horses carry the camp. Budget travellers should weigh acclimatisation nights in Cusco (around 3,400 m) into the total, since rushing the altitude is the false economy that ends trips early.

Frequently Asked Questions
Which South America trek is best for first-timers?
The Lost City Walking Track in Colombia is the most beginner-friendly because it stays at low altitude and runs as a guided 44 km, 4-day trip with porters and basic camps. The heat and humidity are the main challenge rather than altitude. High-altitude circuits like Ausangate demand prior acclimatisation and are better as a second or third trek.
Do you need to acclimatise before trekking in Peru?
Yes. Ausangate and Salkantay both climb above 4,500 m, so spend at least two to three days in Cusco (3,400 m) before starting. Skipping acclimatisation is the leading cause of altitude sickness on Peruvian treks. Drinking plenty of water and avoiding alcohol in the first days helps your body adjust.
What is the highest trek in South America?
Among popular routes, the Ausangate Trek is one of the highest, crossing passes near 5,200 m and circling a 6,384 m peak, with multiple camps above 4,500 m. Some specialist high-altitude routes climb higher, but Ausangate offers the best combination of accessibility and extreme altitude for trekkers.
Is trekking in South America safe in 2026?
The trekking routes themselves are generally safe with a reputable local guide, and the main hazards are altitude, weather and remoteness rather than crime. Check current government travel advice for the specific country and region before you go, book through registered operators, and carry insurance that covers high-altitude evacuation.
Do you need vaccinations for trekking in South America?
It depends on the country and region. For high-altitude Andean treks like Ausangate near Cusco, no special vaccines are required beyond routine ones, since the altitude is above the mosquito line. Jungle routes such as Colombia's Lost City sit in areas where yellow fever vaccination and malaria precautions may be advised. Check current guidance from a travel clinic six to eight weeks before departure, as recommendations are updated regularly for 2026.
