Trekking Viewpoints of Tronador - Stage 1 (Trekking around Lake Mascardi)


A lake and a mountain that exude beauty and history

Lake Mascardi represents one of the most famous lakes in the area surrounding San Carlos de Bariloche. It is located in the Nahuel Huapi National Park and is fed by the waters that come mainly from the glaciers of Mount Tronador, through the Manso River. Thanks to this, it has a coloration in its main body and a different one in its west arm (turquoise, due to the minerals that come from the aforementioned glaciers), named arm Tronador as the mountain.

In this trekking circuit, we will start from the north point of the lake and cross towards the Tronador arm through the Laguna Llum. We will reach the western point of the lake, just where the Rio Manso empties. We will return to Bariloche by transportation through the route that goes to Pampa Linda.




What we present here is the planned route for the crossing, but the exact route, the duration of each stage of the march and the choice of alternative itineraries are subject to different factors such as weather conditions and group evaluation by the guides.

Day 0: It is suggested to spend the night before the trek starts in the city of San Carlos de Bariloche

Day 1: Meeting in San Carlos de Bariloche, downtown area. Presentation of guides and the group; preparations and loading of backpacks. We travel by private vehicle to the northern headwaters of Lake Mascardi. Initial walk of 2 hours to a beautiful beach, called Leones. Then we continue another hour and a half to Laguna Llum, the place of our first camp. Dinner and overnight.

Walking time: 4 hours

Day 2: On this day we will continue to ascend, after bordering the Llum lagoon, to the first great viewpoint of Tronador, the homonymous arm of Lake Mascardi and Isla Corazón. We will then descend a steep hillside to enter the forest. Finally, we border Lake Mascardi along the mentioned arm until we find another beautiful beach, La Volteada. New camp. Dinner and overnight.

Walking time: 8 hours

Day 3: We continue bordering Lake Mascardi on the Tronador arm, until the end, crossing on foot two important streams, such as Casalata and El Claro. Before crossing the latter, we will visit some pools formed by the stream, finally, we will cross the suspension bridge over the greenish Rio Manso Superior, which brings its waters from Mount Tronador. On the other side is our camp, in Tres Alamos, Los Césares Camp. End of the trek (Stage 1) and transfer back to Bariloche.

Walking time: 5 hours.

This is stage 1 of 3 of the main program that continues to Pampa Linda (complete 7-day trek)

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.
