Trekking Crossing the Andes Paso Portillo-Piuquenes

Proposal

The path that marks history

Those extensive valleys of height, interrupted by some solitary mountain refuge. The imposing rock walls. The irregular peaks broken by the white mantles of the glaciers. Everything is still, as in a painting, being us the main protagonists of that painting.

The idea is to enter the heart of the mountain range, ascending through a valley and crossing the very Andes Cordillera through the same place where one of the armies of General San Martin did it more than 200 years ago, an experience that is not easily forgotten.

Modality

Expedition in cross-country mode (joining Argentina with Chile). We carry trekking backpack on the shoulders and with the support of porterage animals, we go up through one path and down through another. Overnight is on wild camps with no services and, occasionally, in mountain refuges (without the comforts of a campsite) in the middle of the Cordillera de los Andes. Physically demanding in 3 of the 7 days.

Dates Season 2023:
  • January 8 to 14th
  • January 22 to 28th
  • February 5 to 11th
  • February 19 to 25th

 

Itinerary

NOTE: Due to the decision not to open non-traditional border crossings such as Piuquenes in the summer of 2021 and 2022, we are going to wait until they authorize the official opening of the crossing, which would allow us to return to the original day-to-day plan that appears in this programming.

Day 1: Meeting 10 am; transfer from the bus station in Mendoza city. It is a private transfer that we include in the program for those who are not already in Tunuyan. Preparation of the backpacks, presentation of guides + general technical talk and transfer to the Portinari Shelter of the National Gendarmerie.

Faq

Do I need to be trained?

For any mountain activity you need to have previous physical preparation, or be physically active. In this case, we suggest training well in aerobics (going for a run two to three times a week, cycling or swimming) and doing a good leg workout (gym, crossfit, AEX training, etc.)

Do I need to have previous experience?

It is a requirement to have walked at least once previously with a cross-country trekking backpack on a MOUNTAIN trek, even if it is for 1 day (8 hours). It is also important that you have slept in a tent in a sleeping bag.

Where do you spend the night?

The overnight is done in mountain camps in igloo-type tents, comfortable and for 2/3 or 4 people. To share.

The last night: we include one night of accommodation in a classic-simple hostel, with rooms to share, in Santiago de Chile. If you want to have another type of accommodation you can reserve yours on your own.

Do I have to bring a tent?

The tents are included in the service. If you want to bring your own, ask us.

Is there a bathroom?

No. There are no toilets or chemical toilets. Everything is in nature, delimiting sectors. And you have to maintain the hygiene of the place, taking the papers.

What is the weather or temperature?

Although the time of year is optimal for this journey, in Andean and/or wild areas, temperatures tend to drop at night. There may be the possibility that a storm will touch us, hence the importance of personal equipment, they cannot miss anything that we detail in the equipment list.

Are there rest stops?

The stops are given with a frequency and graduation according to the intensity. There are stops for lunch, snack, and rest.

From what age can they do this activity?

From 16 years of age. We also recommend that you contact us before registering or registering a minor (minor must cross with the authorization of the parents, mother and father or guardians)

How much does the backpack weigh?

Everyone can walk lightly up to the Piuquenes border marker, but it is essential that you always carry an expedition backpack, not a small attack backpack, since from the border marker to the end, on the Chilean side, there are 3 hours of descent where each one must carry all their equipment (sleeping bag, insulation, used clothing, clean change of clothes, hygiene, etc).

Until the border milestone (almost the entire route), each person must carry only what they will use during the day: water (the longest day starts with 4 liters), coat, sunscreen/lipstick, flashlight, lunch box marching etc.

Is there a porterage service?

We have a mule porter service, which will carry the general equipment, such as kitchen items, food, tents, and security items. They also carry some of your equipment, an approximate of up to 7 kilos per person. Within the Argentine territory.

What do we eat?

In all our expeditions we offer the service of meals IN FULL BOARD PLAN:

  • March lunches (cold meals): Milanese and tomato sandwiches, cold cut sandwiches, appetizers, salads, tapas, etc.
  • Dinners: Vegetable-bacon-red chorizo ??stews, Chicken and vegetable casseroles, Pasta with various sauces or stew, Roast meat (Chivito), Chaw Fan, Chicken with rice in a saucepan....
  • Breakfasts and snacks: Tea, Coffee, Cappuccino, Mate Cocido, Mate, Milk powder; bread, cookies, jam, honey, dulce de leche; cereals, fruit

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.
