Southern Transpatagonic Trekking - San Martin Lake to Del Desierto Lake, El Chalten


A Trip to Remember

The Estancia El Condor is located in the southeast extreme of Lake San Martin, an emerald color rarely seen. The mentioned lake is called O'Higgins on the Chilean side. Our proposal invites you to walk along the shore of the lake, from Argentina, to cross to Chile to the Candelario Mancilla post, a place guarded by Carabineros (Chilean Police). From there we´ ll continue through the Chilean forests until crossing again to Argentina in the Lago del Desierto area, where we finish, after crossing the lake. And from there, we go to El Chalten, "The Trekking Capital". It does not present technical or physical difficulties.

Modality and difficulty
Shoulder backpack Expedition. There are permanent slopes, between forests and high passes. You have to carry your own backpack with personal equipment and a bag of group food. Overnight stays are in wild areas (without toilets), in a tent and / or stalls.


Day 1 ESTANCIA EL CONDOR. From El Calafate, we traveled by vehicle along Route 40 to Lake San Martin, Estancia El Cóndor. Lunch. Short walks through the area and the lake. Dinner and overnight in the Estancia.

Day 2 We start our first section of the route, along the trails that leave the ranch to the west. We skirt the lake again and again and walk through a typical forest of the region on an open road. We arrive at La Nana post in the afternoon, where we will spend the night. Dinner and overnight.

Day 3 Continued along the coastal path and increasingly closed, we reached the Martinez de Rozas refuge in ruins at noon. Lunch. From there we enter the great valley of the Río Martinez de Rozas. We will cross the river a couple of times to our next camp, close to the old Altamirano Post. Camp, campfire. Dinner and overnight.

Day 4 We raise camp again and we´ll go, always through the same valley, towards the sources of the riverbed. We´ll cross the river several times and pass through increasingly complex terrain, such as mallines, forests and closed trails. Finally we will look for a new camp near the old Torito Minero post. Camp, campfire, dinner and overnight.

Day 5 Lago del Desierto: We continue our ascending path towards Paso La Unión, already outside the vegetation limit. Crossing the pass, perhaps with snow, we will descend to a new valley to reach the Lago del Desierto and then skirt it until its southern head. Last camp on the mountain.

Day 6 El Chalten: After breakfast, everyone will have the option of going up and down to the Huemul glacier, for our last excursion. Finally we set up camp and a vehicle will take us to El Chalten. Overnight in hostel. End of our services.

Day 7 Return home or continue with new adventures ...


Interesting extra options:

Stay one or two more days in El Chalten to make circuits on foot: Laguna de los Tres, Laguna Torre. Excursion on board the Viedma Glacier, etc.

Difficulty graduation

Mochila: Peso / Duración de la Jornada.

Exigencia Física

Técnico: Dificultad en el Terreno / Equipo.

Fortaleza Psicológica

Exposición a la Altura

Backpack (M)

This point has to do with the weight that we must carry in our backpacks. Trekkings or crossings where we have pack animals allow us to bear less weight on our backs. And the multi-day journeys in Patagonia (without the option of having pack mules) generally make us carry more weight, especially in the early days.

20% Up to 5 Kilos: Short excursion walks / Trekking Talampaya

40% Up to 8/10 Kilos: Round-trip trekking / Vallecitos 3 and 4-day programs

60% Up to 12/15 kilos: Crossing trekking with porting / Crossing of the Andes Paso Portillo

80% More than 15/18 kilos: Cross-country trekkings with little or no portage / Trekkings in Patagonia (Paso Vuriloche, PN Lanin or Nahuel Huapi, etc)

100% More than 25 Kilos: With a lot of equipment on top and little or no porting / Continental Ice

Fitness (F)

We consider physical demands to the wear that we can suffer both aerobic (climbs = possible shortness of breath) and muscle (resistance = many hours walking) and of legs and joints (descents = knees / ankles).

20% half a day or less with little unevenness.

40% more sustained slopes and longer days in the activity. 2-3 days / more than 6 hours per day.

60% Long ascents and descents with a longer duration. Ascents to more than 4000 meters in the central mountain range / intense 4-day trekking (Uruguayan plane)

80% Important work of legs in resistance. Very long days. Very long day ascents (Lanin - Domuyo) or more than 5000 meters. Ice courses.

100% Maximum demand. Aerobic work and constant effort on legs. Continental Ice, Aconcagua, mountains of more than 6000 meters.

Technical (T)

The technical difficulty is mainly based on the terrain. How much can it cost us to climb a slope, if it is very steep or if we have to use our hands in some section (simple climbing), both in rock and snow-ice, or materials such as crampons and pegs in other ascents.

20% flat land

40% trails with moderate ups and downs. General crossing trekkings . Sierra de la Ventana, Córdoba, Patagonia, Cuyo, north, others. Classic ascents

60% Steeper slopes and trails. Possible use of crampons. Domuyo, Cordón del Plata, Cordillera Central.

80% Mixed terrain, with snow or ice. Alvear, Lanin, Tronador. Bolivia, Peru.

100% Highly technical terrain. Glacial transit and climbing in sections. Hill climbing with sections on slopes of more than 60 ° inclination

Psycho (P)

We maintain that this point, the psychological factor, represents a relevant factor. Each one needs a factor of conviction, confidence, self-control and will power to achieve a goal. And depending on the attitude with which we face distances, slopes, terrain and many other objective factors, we can achieve performance with very different results.

20% We will not be much affected.

40% This is a normal level of attention.

60% We require more motivation, enthusiasm and concentration.

80% The activity will require us to be very connected and convinced.

100% Maximum control and emotional-psychological performance.

Adventures (A)

It is the factor that, the height above sea level, influences us depending on the activity we carry out. Managing and overcoming symptoms caused by altitude is the key to this point

0% + sea level.

20% Up to 2000 masl.

40% + 2000 masl.

60% + 4000 masl.

80% + 5000 masl.

100% + 6000 masl.
