Choose the Lost City trek for a guided 46-km jungle hike to a 1,200-year-old ruined city in tropical heat, and the Vuelta al Huemul for a self-supported 65-km technical Patagonia circuit with glacier views, zip-line river crossings and fierce wind. Lost City is moderate and supported; Huemul is hard and committing.
Both are roughly 4-day South American treks that top many bucket lists, but they could hardly be more different. The Lost City trek in Colombia is about culture and jungle in 30°C heat, while the Vuelta al Huemul in Argentine Patagonia is about raw wilderness, glaciers and self-reliance in cold, windy conditions. This 2026 comparison helps you pick the right one.

Which is harder, Lost City or Vuelta al Huemul?
The Vuelta al Huemul is clearly harder. It is longer at 65 km, fully self-supported, and technical: you complete two Tyrolean (zip-line) river traverses using a harness and pulley, cross the exposed Paso del Viento and Paso Huemul, and battle Patagonian winds that regularly exceed 60–80 km/h. The Lost City trek is moderate, guided, and free of any scrambling, its difficulty is heat, not terrain. Beginners can manage Ciudad Perdida; Huemul demands prior multi-day and basic technical experience.
Which has better scenery?
This depends on what moves you. The Lost City trek rewards you with dense Sierra Nevada jungle, river pools and a 1,200-year-old Tairona city of stone terraces predating Machu Picchu. The Vuelta al Huemul delivers one of the great panoramas in hiking: from Paso del Viento you look out over the Southern Patagonian Ice Field, the third-largest body of ice on Earth, plus the Viedma Glacier and distant Cerro Torre. One is cultural and green; the other is glacial and vast.
Which is easier to organise?
The Lost City trek is far simpler. You book one of four authorised operators for a fixed USD 550–650 in 2026, and everything, food, water, sleeping setup, is handled. The Vuelta al Huemul is self-organised from El Chaltén: you register with park rangers, pass a mandatory gear check (harness, pulley, carabiners), carry four days of food, and wild-camp. It is free but logistically demanding.
Which should you choose in 2026?
Pick the Lost City trek if you want culture, warmth, a guided experience and a moderate challenge, or if it is your first multi-day trek. Pick the Vuelta al Huemul if you are an experienced, self-sufficient hiker chasing wild Patagonian scenery and you are comfortable with technical river crossings and severe weather. Many hikers eventually do both as part of a wider tour that might also include Peru's Ausangate Trek.
How packing differs between the two
Lost City is a light, hot-weather trek: a ventilated 35–50 L pack such as the Osprey Atmos AG 65 and quick-dry clothing are enough. Huemul is a cold, self-supported load: you need a larger 50–60 L carry like the Osprey Aether 65 or the lighter Zpacks Arc Haul Ultra 60L to fit a tent, four days of food and warm layers. Compare real pack weights in the HikeLoad gear database before deciding.
For official planning, see Colombia's national parks authority for Ciudad Perdida and Argentina's national parks service for Los Glaciares and the Huemul circuit.
Which trek fits your travel style?
Think about how you like to travel, not just how fit you are. The Lost City trek suits hikers who want a structured, sociable, all-inclusive experience: you book once, show up, and a guide handles route-finding, cooking and camp logistics across the four days. It is ideal for travellers short on time, new to multi-day trekking, or uneasy about self-navigation in a foreign country. The cultural payoff, a 1,200-year-old Tairona city, gives the trek a clear narrative arc that day-hike-focused travellers love.
The Vuelta al Huemul rewards the opposite temperament. It is for independent hikers who relish self-sufficiency, want to set their own pace, and accept that weather may rewrite the plan. There is no group to wait for and no guide to follow, but also no safety net beyond your own preparation, which is exactly the appeal for experienced trekkers. Budget shapes the choice too: the Lost City trek's roughly USD 550–650 operator fee in 2026 buys convenience, while the Huemul circuit's free permit suits hikers willing to organise their own transport, food and gear. If you are planning a longer South American trip, the two complement each other perfectly, with Peru's Ausangate Trek adding a third, high-altitude flavour. Map all three across your calendar on the HikeLoad hike planner.
Season is the other deciding factor, and the two treks sit on opposite calendars. The Lost City trek peaks in the northern-hemisphere winter, December to March, while the Vuelta al Huemul peaks in the austral summer, December to February, when Patagonia's Tyrolean cables are installed. That overlap means you cannot easily do both in a single short trip, since each is at its best in the same window, but it also gives flexibility: a hiker travelling in, say, July could choose the Lost City trek's shorter dry break, whereas a December traveller could reach either. Fitness progression is worth considering too. Doing the moderate, guided Lost City trek first builds confidence and multi-day stamina, making the harder, self-supported Huemul circuit a logical next step rather than a leap. Sequencing your South American treks from easier to harder is the safest way to build toward the continent's more demanding routes through 2026.
Frequently Asked Questions
Is the Lost City trek or Vuelta al Huemul more famous?
The Lost City trek is more famous internationally as Colombia's signature multi-day hike and a guided bucket-list trip. The Vuelta al Huemul is a connoisseur's route, less known but highly respected among experienced trekkers for its ice-field views and technical character.
Can a beginner do the Vuelta al Huemul?
It is not recommended for beginners. The Vuelta al Huemul is a 65-km, self-supported circuit with Tyrolean river crossings, exposed glacier passes and severe Patagonian wind. It suits hikers with prior multi-day experience and basic technical skills, unlike the guided, beginner-friendly Lost City trek.
Which trek is cheaper, Lost City or Vuelta al Huemul?
The Vuelta al Huemul is cheaper to access because its national-park permit is free; you only pay for transport, food and gear. The Lost City trek costs roughly USD 550–650 in 2026 because it must be done with an authorised operator that includes all meals and logistics.
When is the best time for each trek?
Hike the Lost City trek from December to March, the Sierra Nevada dry season, avoiding the September closure. Hike the Vuelta al Huemul from November to March during the austral summer, ideally December to February when the Tyrolean traverse gear is installed and weather windows are best.
Do both treks require a guide?
The Lost City trek legally requires one of four authorised guides because it crosses indigenous land. The Vuelta al Huemul can be done independently after registering with park rangers and passing a gear check, though some hikers hire a guide for the technical crossings and route-finding.
