If you want to experience Patagonia in its rawest form, the four-day Huemul Trek in southern Patagonia will tick every box. From cable-assisted river crossings, steep climbs, and unforgettable glacier views, your dreams of witnessing Patagonia’s untamed beauty will come alive.

Quick Overview

The Huemul Trek is a 60km loop that starts and ends in Los Glaciares National Park, Santa Cruz, Argentina. It’s the best hike in Patagonia that you’ve never heard of – known for its steep passes, wild weather, and glacier viewpoints. This ultimate Patagonian adventure is located right at El Chaltén, and its turquoise lakes, remote glacial views, and rugged landscapes will make you want to hike it twice – trust me, I seriously considered it.

About the Huemul Circuit Trek

The Huemul Circuit Trek takes the cake: it’s a fill-up-your-water-in-the-glacier, pack-your-rubbish-in-and-out, no-phone-reception, no-huts kind of adventure.

Did I mention there are beautiful native flowers everywhere?

 

If you haven’t hiked on a glacier and want to scratch that itch, this one’s for you. If you love a loop trek with equally thrilling and unique challenges around every corner, the Huemul is calling your name. And if you want to experience the most remote glacier views in all of Argentina, this hike’s raw beauty definitely outweighs your heavy pack.

History of the Huemul Circuit Trek

The history of the Los Glaciares National Park is one tied to conservation, exploration, and the power of ice. Indigenous Tehuelche communities were the first stewards of the land, living alongside these glaciers in harmony for thousands of years as skilled hunter-gatherers.

They navigated valleys and rivers seasonally, long before rope crossings, relying on an inextricable understanding of the land and weather to survive. The Tehuelche faced the same unforgiving winds, obstacles, and unpredictable conditions trekkers experience today, but the glaciers, winds, and open plains were part of daily life.

The Southern Patagonian Ice Field… I can’t believe this place is real

 

The significance of the Southern Patagonian Ice Field became clear in the early 1900s as exploration increased when scientists, mountaineers, and explorers ventured into the region to chart the vastly astonishing landscape. These early expeditions mapped the terrain and deepened global understanding of one of the largest ice systems on Earth.

Awareness of the region’s ecological significance led to the creation of Los Glaciares National Park in 1937, solidifying the protection of its glaciers, wildlife, and fragile ecosystems. Unlike many trails in Patagonia, the Huemul Trek has remained largely untouched – offering a rare chance to trek through a landscape that still feels frozen in time (don’t mind the pun).

Now, for the origins of the name – the Huemul deer. This creature is a shy but strong, endangered species native to Patagonia. Once widespread across southern Argentina and Chile, Huemul populations declined dramatically due to hunting and habitat loss. Sightings are rare, but we did see a few, and their presence was powerful – an emblem of Patagonia’s robust core, and a reminder of why conservation in places this remarkable is so important.

Hiking the Huemul today means embarking on a journey shaped by rich history, cultural ties, and stark wilderness that continues to define Patagonia.

How to Get to the Huemul Circuit

This is excruciatingly easy (ya know, once you get to the southern end of a continent on the other side of the world). The trek starts 6km outside of El Chaltén, so you can easily stay in El Chaltén the night before and get prepared. Most people fly into Comandante Armando Tola International Airport (FTE) from Buenos Aires or Santiago, and from there it’s about a three-hour drive to El Chaltén.

The trail starts from the Los Glaciares National Park Visitor Centre (Guardaparque Ceferino Fonzo) which is a short distance from El Chaltén. This centre is the main contact point for visitors accessing the park’s information, trail network, and mountain areas – so you’ll need to visit it before embarking on the Huemul.

We left a car at the end of the circuit so we could drive back to El Chaltén in time for a sunset drink, but we passed many people hiking the 6km back to El Chaltén, tired and loopy.

Where to Stay on the Huemul Circuit

The beauty of this trek is that it’s a true Patagonian experience – no huts or cabins or toilets or showers unlike the W-trek – there are only a handful of designated wild campsites on the Huemul and you have to be completely self-sufficient. There are singular small cabins at each campsite (refugios), but only for emergencies.

Remember, these huts are heritage and should only be used for emergency accommodation. Make sure you still pack your tent!

The first night’s camp spot at Laguna Toro has incredible wind protection around each tent site (as if you’re a baby bird sleeping in a protective nest), and it’s surrounded by impressive trees.

The second night’s campground at Paso del Viento was my personal favourite because Mimi and I took a dip in the lake (as all true Aussies do when they see a large mass of undrinkable water). It also had a spectacular view of the Southern Patagonian Ice Field.

The final campground at Bahía de los Témpanos was a picturesque scene of icebergs bobbing on the water’s surface right in front of the tents. We didn’t camp here however as we wanted to ‘keep pushing on another two hours’ (you know the feeling?!). Instead we reached a more secluded campsite on the beach at Campamento Bahía de Hornos.

Each campground has rocky windbreaks around tent spots, water sources from nearby rivers, and most have shelter from trees: it’s five-star accommodation if you like ‘roughing it’.

Skill Level

Advanced

This is the alpine, so checking the weather forecast at The Los Glaciares National Park Visitor Centre is a must, as you need at least two ‘really good weather’ days for days two and three, as they’re most exposed to the glacial fields.

Please note: This adventure is dangerous if there’s been recent rain in the area or if rain is on the forecast. Best to save this one for a clear day.

 

Just one of the staggering views on Day 2

 

The Los Glaciares National Park Visitor Centre provides vital orientation about trails, safety regulations, and environmental guidelines, which is paramount before embarking on the Huemul. It’s also the place where hikers must register in person, receive a safety briefing, confirm their intended itinerary, and hire mandatory river-crossing gear (if you don’t already have a harness, carabiner, and safety rope).

For this hike you need to be at an advanced skill level: you should be very capable and experienced in the outdoors before stepping foot on this trail.

What It’s Like to Hike the Huemul Circuit

Day 1 – El Chaltén to Toro lagoon

Distance: 15km
Duration: 6 hours
Difficulty: Intermediate
Campground: Laguna Toro

I had my first stack in under 30 minutes – straight into the mud (laughing hysterically). That pretty much set the tone for day one.

The trail began gently through lenga forest, before quickly turning into flooded, marshy terrain. I was reading the landscape constantly, scanning for higher ground, dodging hidden puddles disguised as solid earth. Navigation was everything.

As we gained elevation, the trees thinned and the wind picked up. By the time we reached Laguna Toro, the landscape opened dramatically – wide valleys, distant ice fields, and running streams. The campground felt ancient, green, and protected and we pleasantly ran into some new friends there too.

Day 2 – Toro Lagoon to Paso del Viento

Distance: 12km
Duration: 6 hours
Difficulty: Advanced
Campground: Pasa del Viento Shelter

This is where the circuit got serious.

The day started with a river crossing. This section of the trail consists of a Tyrolean traverse, where hikers clip into a steel cable stretched across the river and use a pulley and harness to pull themselves across while suspended above the water. But as there was already a queue, we crossed on foot instead. Boots off, pants rolled, hearts pounding – the water was glacial, fast, and shockingly cold. It seriously took my breath away.

Then came the glacier approach. The terrain shifted into moraine fields, a mass of rock and debris deposited by a glacier, which meant unstable ground and constant route finding. Every step required focus. The rocks underfoot often weren’t secure, which made balance critical and progress slow. Testing each step on large boulders was essential for safety. There were no markers here in terms of navigation, just careful judgement and backtracking to adjust our route.

Earth or Mars?

 

Getting in and getting out of the glacier was technically the most dangerous part, because of unstable ground and the chance of falling rocks.

As we approached the edge of the Túnel Glacier, the terrain became a mix of loose rock and intermittent ice, with meltwater running between the stones. On the glacier there was no clear single path, but hiking along the left was the safest line forward. The crossing was relatively short and not heavily crevassed, but required slowness and careful foot placement on the ice.

We didn’t use crampons, but mini crampons would’ve provided extra confidence. Trekking poles were great for balance. (This section isn’t highly technical in a mountaineering sense, but it does require route finding on unstable terrain that can make it feel harder than it looks on paper…you can do this!)

The Túnel Glacier crossing was by far one of my favourite parts because, I mean, it’s a glacier crossing!

 

Then we reached the ridge… With staggering panoramic views of the Viedma Glacier and the Southern Patagonian Ice Field, I felt tiny and isolated (a feeling that’s arguably the highlight of this trek), witnessing one of the world’s largest ice systems outside Antarctica and Greenland. I think I said ‘wow’ at least 50 times. The scale is almost incomprehensible. White and blue stretching endlessly, cracked and textured like another planet.

The wind here was relentless. It howled across the pass, strong enough to knock us sideways if we weren’t steady. Not only did this trek take us away from crowds into remote wilderness, it required us to have some grit: facing particularly challenging and unpredictable Patagonian weather. You’ll be far from your comfort zone, but that’s where the magic lies.

Once we made it to the campground, we went for a cold plunge, blasting Cat Stevens as the sun dipped behind the jagged peaks with a couple who’d just got engaged! A delirious game of charades followed. Exhaustion makes everything ten times funnier.

Day 3 – Refugio Paso del Viento to Témpanos Bay

Distance: 16km
Duration: 7 hours
Difficulty: Advanced
Campground: Bahía de los Témpanos

Day three was long and demanding.

The trail traversed high ridgelines with constant exposure. The wind didn’t stop. The path alternated between narrow dirt tracks and steep, rocky descents where we were half hiking, half sliding. Loose scree demanded balance and patience.

Then came the infamous descent – steep, rugged, and relentless. We needed coordination and confidence here. There were a few stacks among us, but also plenty of belly laughs.

We saw wild horses grazing in the valley below, scattered cow skulls bleached by the sun, and endless views of turquoise water fed by glaciers. By the time we reached camp, we collapsed into a giant pot of hot chocolate.

Day 4: Témpanos Bay – Túnel Bay

Distance: 20km
Duration: 7 hours
Difficulty: Intermediate

Ahh, the last little push.

This section felt different – wider valleys, rolling terrain, and big skies. We passed Chilean cattle grazing freely, wooden fences cutting across golden fields. It felt cinematic.

The final thrill? The zipline across the Túnel River. It’s the most fun way to end the circuit.

As we walked the final kilometres back toward civilisation, the mountains slowly fell behind us. Our legs ached, but our packs didn’t even feel like they were there anymore.

The Huemul Circuit isn’t polished or comfortable. The trail is raw – muddy, rocky, exposed, unpredictable. You’re constantly adjusting to wind, terrain, and weather. But it’s got the kind of views that don’t quite translate through a camera lens.

Can we do it again already?

Tips for Hiking the Huemul Circuit

  • Hang your food on a tree away from your tent, in a bag. There are mice – they’re cute, but hungry
  • If you want to wash or go to the bathroom, go away from water sources!
