Hiking the Fitz Roy Trail: A Journey Through the Argentina-Chile Border

The Fitz Roy Trail, located on the Argentina-Chile border, is a destination for outdoor enthusiasts exploring Patagonia’s stunning natural beauty. The trail takes hikers through rugged terrain, past crystal-clear lakes, and rivers, and offers breathtaking views of the iconic Mount Fitz Roy.

In this article, we will take a closer look at the trail’s history, the logistics of hiking it, and what to expect along the way.

Brief History of Fitz Roy Trail

The Fitz Roy Trail, which runs along the Argentina-Chile border, has a long and illustrious history. Mount Fitz Roy, a towering mountain named after Robert Fitz Roy, HMS’s captain during Charles Darwin’s historic expedition to the region in the 1830s, inspired the trail.

The area around Mount Fitz Roy has always drawn adventurers and explorers. European mountaineers began exploring the region and attempting to climb the mountain in the late 1800s and early 1900s. A team of French climbers led by Lionel Terray and Guido Magnone accomplished the first successful ascent of Mount Fitz Roy in 1952.

The Fitz Roy Trail was built in the 1980s and has become a famous hiking destination for nature enthusiasts worldwide. Hikers will travel through Los Glaciares National Park, founded in 1937, to safeguard the region’s natural beauty and biodiversity.

The Fitz Roy Trail is famous today for its beautiful landscape, rugged terrain, and rich history. Hikers can explore glaciers, mountains, and pristine lakes while admiring Mount Fitz Roy and the surrounding countryside. Visitors worldwide continue to flock to the route, eager to experience the beauty and adventure of this one-of-a-kind place.

Description of the Fitz Roy Trail

The Fitz Roy Trail is a 40-kilometer (25-mile) walk through Patagonia that crosses the Argentina-Chile border. The track begins and ends in El Chalten, Argentina, and leads walkers through the Los Glaciares National Park, a UNESCO World Heritage Site recognized for its breathtaking natural splendor.

Although the track is well-marked and maintained, hikers should be prepared for rugged terrain, steep ascents and descents, and unexpected weather. Hikers will pass through some of the most spectacular landscapes on the planet, including glaciers, mountains, and crystal-clear lakes and rivers.

Mount Fitz Roy, a towering mountain that rises to a height of 3,405 meters (11,171 feet), is one of the trail’s highlights. The peak can be seen from numerous locations along the trail and provides a spectacular backdrop for hikers as they traverse the rocky Patagonian environment.

Other significant features along the walk are Laguna de los Tres, a beautiful lake with breathtaking views of Mount Fitz Roy; Laguna Torre, another picturesque lake surrounded by glaciers and mountains; and the Viedma Glacier, one of the region’s largest glaciers.

Ways to Get to Fitz Roy Trail

Fly from Buenos Aires to Calafate in southern Patagonia, then take a three-hour bus (we recommend Chalten Travel) to El Chalten, Fitz Roy explorers’ home base—expert advice: Buy groceries and trekking food in Calafate because costs and selection in El Chalten soar. Also, check the weather forecast before time; if the weather isn’t cooperating, it’s best to wait it out in Calafate rather than El Chalten. After all, who wants to ride on a bus for three hours in the pouring rain only to be stranded in a little town with little to do if they can’t hike?

When to Go: Weather and Season

The best time to visit the Fitz Roy Trail, the Laguna de Los Tres hike, depends on your interests and what you want to see and do. Here are a few tips to put into consideration:

– Time:

The weather in Patagonia is notoriously erratic. Because of its location, it can be highly windy, especially in early summer (end of November/early December), with temperatures ranging from the upper 70s to the low 40s. During this time, temperatures are warmer, there is less wind, and there is more daylight. However, this is also the busiest season, and you can catch crowds on the trail and in the nearby town of El Chalten.

– Crowd:

If you want to avoid the crowds, visiting the Fitz Roy Trail in spring (September to November) and fall (March to May) is best. The weather is more relaxed and fickle during these seasons, but the trails are calmer, and you can have a more peaceful experience.

– Hiking conditions:

The Fitz Roy Trail is open year-round, but some sections of the trail can be closed or difficult to access during the winter months (June to August) due to snow and ice. If you plan on hiking in the winter, you must be fully equipped and prepared to deal with cold and potentially hazardous conditions.

The best time to visit the Fitz Roy Trail depends on your priorities and what you want to experience. Regardless of your time, check the weather forecast and road conditions before you go and prepare accordingly. 


For the Fitz Roy hike, there usually are two options for lodging: camping or hostels and apartments.

Camping: There are numerous camping options in Patagonia, Argentina, near El Chalten. You must bring your own tent and cooking equipment.

Along the hike to Laguna de Los Tres, there are two campsites: Campamento Poincenot and Campamento Laguna Capri (by the lake). Camping in Patagonia is an excellent option for hikers.

Families can camp near Laguna Capri (one of the Fitz Roy hike’s viewpoints). Because Patagonia has no pollution, you can drink the water from lakes and streams. There are portable toilets in Patagonia tent sites, and you cannot cook with fire.

Hostels and Apartments: Most people who go on day hikes in the nearby mountains stay in El Chalten. El Chalten is a very small town, yet it has a lot of apartments and hotels. Examples of famous and comfortable Hostels in El Chalten are;

El Chalten’s Aylen-Aike Hostel

Aylen-Aike is a combination of the terms ’ember’ and ‘warm spot’ in the original tongue, so you can expect to be comfortable and toasty in this Hostel, which is one of the reasons it is frequently booked. Sturdy, comfy bunk beds are available in four, six, and eight-bed dorm arrangements, and a cheap breakfast option if you want to quickly fill up and hurry out the door searching for some mountains.

Hostel Rancho Grande, El Chalten

During your stay in El Chaltén, Hostel Rancho Grande will make things easier. You only need to go outside for the tour. The Hostel offers shuttle services, tour and trail information, an onsite café, and a 24-hour restaurant. It’s also in a great place, close to several restaurants and bars and only a few hundred meters from Fitz Roy trails.

Condor de los Andes, El Chalten

You might assume a high price to stay here after entering the front door, seeing the gorgeous lounge area, hearing the quiet background music, and feeling the relaxing attitude. Yet, the fantastic dorms are reasonably priced compared to the rest of town. Large hardwood bunks for uninterrupted relaxation, a kitchen for pre- or post-trail meals, and a relaxing lounge to socialize with other travelers and trekkers.

Food and Water

El Chaltén has a few food stores where you may get snacks and necessities. Supermercado El Chalten provided the most variety, incredible fresh produce, and the best prices.

El Chaltén’s grocery costs are more expensive than the rest of Argentina. If you are on a limited budget, stocking up at the El Calafate store is best. El Chalten is a tourist hotspot with many restaurants to pick from.

There are also some fantastic bars and craft brewers where you can relax with a nice beer after a long day of hiking. La Cervaceria is a favorite location for many because of its craft beer selection, and it’s also a nice place to meet other travelers.


Swimming in the Fitz Roy Trail can be a new and exciting experience, but it’s important to note that the water in this area can be freezing, even during the summer months. The main body of water on the trail is Laguna de Los Tres, located at the foot of Mount Fitz Roy. The water in the lake is fed by melting glaciers, so it is often frigid.

Although it is possible to swim in the lake, it is not recommended for inexperienced swimmers or those not prepared for cold water. If you choose to swim in a lake, it’s essential to be aware of the risks and take appropriate precautions, such as wearing a wetsuit or other protective gear. It is also essential to be aware of the impact of human activities on the area’s natural environment. Swimming in lakes or other bodies of water on the trail can harm the local ecosystem, so it is essential to follow the principle of “Leave No Trace” and respect the natural environment in the area while enjoying the trail.
