Best time of the year to trekking to Fitz Roy Mountain
The best time of year to trek Fitz Roy is in December, January and February, although it is of course the busiest time of the year for tourists.
If you want to avoid the crowds of tourists, November and even March are also good times to hike the Fitz Roy trail.
However, as El Chaltén is located in the middle of the Andes, its weather is totally unpredictable, even if you do the trekking to Fitz Roy in the middle of summer. It may be that you start the trekking with clear skies and when you arrive at the Los Tres lagoon the sky is covered with clouds and you cannot see the Fitz Roy. Or vice versa.

Trekking to the Fitz Roy mountain on your own, step by step
Starting from the village of El Chalten, there are several must-visit photo stops along the 10.2 kilometre journey to the Laguna de los Tres. Starting from kilometre 0, which is indicated on the Fitz Roy trail sign, the stops are as follows:
- KM 0.7 Río de las Vueltas viewpoint: up to here it is a gentle slope overlooking the valley.
- KM 4 Laguna Capri and views of the Fitz Roy: the path becomes practically flat surrounded by the Patagonian forests until you reach the beautiful Capri Lagoon. Here you can stop for a rest and a light lunch with views of Fitz Roy. Weather permitting, you will be able to see this imposing hill from the lagoon.
- KM 8 Poincenot campsite: the path continues without much ascent to the Poincenot campsite. Surrounded by trees it has a small stream where you can drink and refill water, latrine toilets and camping area. If you want to see Mount Fitz Roy and the Laguna de los Tres at sunrise, this is the mandatory stop to sleep and get up very early the next day.
- Km 10,2 Laguna de los Tres: the last kilometre before reaching the Laguna de los Tres is the most difficult one, a very tough climb but with a great reward.
Once you reach the top you will see, weather permitting, the silhouette of Fitz Roy reflected in the water of the Laguna de los Tres, a spectacle of nature that you will never forget. Here you should take enough time to take pictures, relax and contemplate the beauty of the Patagonian landscape.
The return is along the same path, which takes about half the time it takes to climb, although there is also the option of continuing on to the viewpoint at the Laguna Sucia. This is the path that goes off to the left and leads to a waterfall overlooking the lagoon (which is not dirty at all).
