One of Patagonia’s Original Expeditions
Explore
oday the route is internationally known as the Huemul Circuit, but in Patagonia it has always been known as the Vuelta al Huemul.
Created by Fitz Roy Expediciones in the early 1990s and led by Alberto del Castillo, this pioneering expedition remains one of Patagonia’s most iconic multi-day trekking experiences.
Distance: 16 km
Elevation Gain: +550 m
Hiking Time: 6–7 hours
Accommodation: Laguna Toro Campsite
The expedition begins in El Chaltén, following quiet valleys beneath the granite walls of Fitz Roy and Cerro Torre before entering the remote lenga forests that lead towards Laguna Toro.
As the landscape gradually becomes wilder, we leave the busiest trails behind and enter one of the least visited sectors of Los Glaciares National Park.
By late afternoon we arrive at Laguna Toro, where we set up camp beside the lake and prepare for the first major mountain stage of the expedition.
After breakfast we cross the Túnel River, either by Tyrolean traverse or depending on river conditions, before beginning the long ascent towards Paso del Viento.
The climb rewards us with one of Patagonia’s most breathtaking panoramas as the Southern Patagonian Ice Field suddenly unfolds before us.
After spending time at the pass we descend to our campsite, surrounded by glaciers and high mountain scenery.
Distance: 10 km
Elevation Gain: +600 m
Hiking Time: 5–6 hours
Accommodation: Paso del Viento Campsite
Distance: 9 km
Walking time: 6–7 hours

we continue around Cerro Huemul through alpine meadows, rocky ridges and spectacular viewpoints overlooking the immense Viedma Glacier.
From Paso Huemul we enjoy one of the finest panoramic views of the expedition before beginning the long descent towards Bahía Témpanos, where we spend our final night beside Lake Viedma.
Our final morning begins with a short walk along the shores of Lake Viedma before boarding the boat for one of the highlights of the expedition.
From the water we approach the towering face of Viedma Glacier, gaining a unique perspective of the ice that cannot be seen from the trail.
After the navigation we arrive at Bahía Túnel, where our transfer is waiting to return to El Chaltén.
Distance: 4–5 km of hiking
Elevation Gain: Minimal
Navigation: Lake Viedma to Bahía Túnel
Transfer: Bahía Túnel → El Chaltén
Today, hikers around the world know this expedition as the Huemul Circuit. Long before it became one of Patagonia’s most celebrated trekking routes, local mountain guides simply called it the Vuelta al Huemul.
In the early 1990s, Alberto del Castillo created the Vuelta al Huemul as a guided mountain expedition, becoming the first to lead the complete crossing with Fitz Roy Expediciones. More than three decades later, we continue guiding the same route with the philosophy that inspired it from the very beginning: small groups, sound mountain judgment and a deep respect for Patagonia’s wilderness.
The Vuelta al Huemul is far more than a trek around a mountain. It is a true Patagonian expedition through remote valleys, glacier crossings, high mountain passes and the immense landscapes surrounding the Southern Patagonian Ice Field. Every day reveals a different face of Los Glaciares National Park, far beyond the trails most visitors ever experience.
No two expeditions are ever the same. Weather, river conditions and the mountains themselves shape each crossing, and our guides adapt each day to the conditions, ensuring every decision is made with safety, experience and respect for the environment.
Every Vuelta al Huemul expedition is carefully planned around mountain conditions, weather forecasts and the experience of each group.

Everything you need to know before joining this adventure.
Patagonian weather is famously unpredictable and conditions can change rapidly, even during the summer months. We recommend dressing in layers and carrying waterproof clothing throughout the day to ensure a comfortable and enjoyable experience.
Most of our day treks do not require previous mountain experience, although a reasonable level of fitness is recommended. Some hikes, such as Laguna de los Tres, involve a full day of hiking with significant elevation gain, while others are more accessible.

Our guided day hikes range from moderate walks to challenging mountain trails. Each trek differs in distance, elevation gain and hiking time. Every adventure page includes detailed information so you can choose a hike that matches your fitness level and outdoor experience.
We recommend sturdy hiking shoes or boots, layered clothing, a waterproof jacket, sun protection, sunglasses, water and a small backpack. Weather in Patagonia can change quickly, even in summer, so it is important to be prepared for wind, rain and temperature changes during the day.
Patagonia’s weather is unpredictable, and our guides constantly assess mountain conditions. If necessary, departure times, routes or objectives may be adjusted to keep the experience safe and appropriate for the group.
