El Chaltén was founded in 1985, largely to settle a border dispute with Chile, and has since become Argentina's trekking capital. Its greatest asset is administrative rather than scenic: the trails start in the village. No shuttle, no permit, no entrance fee, no booking system.
After the paperwork of Torres del Paine on the other side of the massif, this comes as a considerable relief. You wake up, look at the mountains from the street, decide what the weather will allow, and walk out of your accommodation onto the trail. That is the whole of the planning.
What follows is four walks that cover the range from an afternoon stroll to a genuinely long day, plus the weather strategy that determines which one you should be doing.
The weather strategy, first
Fitz Roy is cloud-covered far more often than it is clear. That is not bad luck; it is a granite massif standing in the path of the Southern Patagonian Ice Field, and it generates its own weather.
The local approach is to think in clear windows rather than clear days. Check the forecast each evening and choose the next day's walk then, not before you arrive and not a week out. If a window appears, spend it on Laguna de los Tres, because that is the walk whose payoff depends entirely on the summit being visible. Save the walks that work in cloud for the days that are in cloud.
This is also why three or four nights in El Chaltén is the right number. Two nights gives you one attempt at the weather and a reasonable chance of leaving having seen nothing.
Laguna de los Tres
Around 20km return, six to nine hours, hard.
The signature walk, and the one on the postcards. The trail leaves from the northern end of the village, climbs gently through beech forest and across open country for two-thirds of its length, passes Laguna Capri where most people take their first proper look at the massif, and then climbs about four hundred metres in the final kilometre on loose rock and steps.
That last kilometre is genuinely steep and it is where the walk earns the hard rating. It is not technical, but it is relentless and it is fully exposed to wind.
The lake at the top sits directly beneath Fitz Roy, close enough that the scale stops making sense. If you have the energy, walk a few hundred metres right along the moraine to look down on Laguna Sucia, which almost nobody does.
If the forecast is poor, walk to Laguna Capri instead — around a third of the distance, no climb, and a fine viewpoint in its own right — and turn back. There is no merit in doing the final ascent to look at cloud.
You can also break the walk by camping at Poincenot, near the base of the climb, and going up for sunrise, which is when Fitz Roy catches red light for a few minutes. The campsite is free and has no facilities.
Laguna Torre
Around 18km return, five to seven hours, moderate.
Flatter and considerably easier than de los Tres, following the Fitz Roy river valley west to a lake at the foot of the Grande glacier, often scattered with small icebergs, beneath the improbable granite spire of Cerro Torre.
The reason to know this walk is that it works when the weather does not. The lake, the glacier and the icebergs are all at ground level, so the walk delivers even if Cerro Torre itself is invisible — which it usually is, because it is one of the most consistently cloud-wrapped mountains in the world.
There is a viewpoint about an hour in, at Mirador Torre, which makes a good short option.
The wind funnels down this valley and hits the lake shore hard. It is common to arrive at the lake and find you cannot comfortably stand at the water's edge.
Loma del Pliegue Tumbado
Around 19km return, six to eight hours, moderate.
The best overview walk in the area and the one fewest people do. It starts from the national park visitor centre at the southern end of the village and climbs a long, broad ridge that ends facing both Fitz Roy and Cerro Torre at the same time, with the ice field behind them.
The other two walks take you to the foot of individual mountains. This one shows you how the whole massif is put together, which is a different and arguably better thing.
It is exposed for most of its upper length, has no water after the first hour, and is a poor choice in high wind. In clear conditions it is the walk that most repeat visitors name as their favourite.
Chorrillo del Salto
Around 8km return, two hours, easy.
A flat walk north along the road and then a track to a waterfall in the beech forest. It is not a spectacular objective, and that is not the point — this is the walk for an arrival afternoon, a rest day, a day when the wind has made the ridges unpleasant, or an evening when you have three hours of daylight left and nothing to do with them.
It can also be cycled, and bicycles are rentable in the village.
Two longer options
If you have more days, or more ambition, two things extend the range.
The Huemul circuit is a four-day loop with two Tyrolean traverse rope crossings, a pass with a view over the ice field, and a mandatory registration at the park office. It is a serious undertaking with real objective hazards and it requires equipment and experience — it is not a longer version of the day hikes.
Piedra del Fraile and Lago Eléctrico, north of the village, reach the back side of the massif and see very few walkers. Access is via a road that requires a vehicle or a shuttle.
Practical notes
Cash. El Chaltén's ATMs regularly run dry, and the village is small enough that when they do, they stay dry. Bring cash from El Calafate. Card acceptance has improved but is not universal, particularly at smaller guesthouses.
Buses. Services to El Calafate run several times a day and take around three hours. Book ahead in January and February. The bus terminal is at the entrance to the village.
Supplies. There are shops but the selection is limited and prices reflect the distance from anywhere. Buy trail food in El Calafate if you are particular about it.
Water. Streams in the park are drinkable and this is one of the few places where that advice comes without qualification. Carry less water than you think and refill.
Accommodation. Book ahead for January and February; the village is small and fills. Outside those months you can usually arrive and find something.
Registration. Day hikers no longer need to register for the standard trails, but the park office at the entrance is worth ten minutes for the current trail conditions and the forecast, which they post daily.
How it fits with the Chilean side
El Chaltén and Torres del Paine are on opposite sides of the same mountain system and about a day's travel apart via El Calafate. Doing both is the standard Patagonian trip, and the contrast is instructive: one is a permit-and-booking exercise with a spectacular multi-day route, the other is a village with the trailheads at the end of the street.
