Caminata Volcán Lanín: Pared Norte

Lanín Volcan walk: Pared Norte (North Wall)

1st Stage: as from 'Seccional de Guardaparque' (Ranger Station) up to the refuges.

It starts near the 'seccional de Guardparque', after crossing a lengas wood located behind the 'Gendarmería' post. When the road finishes, you will go along a pedestrian path that crosses Turbio Stream and gets to "espina de pescado" (bone fish), name given to a route due to its unusual shape, caused by the side glaciers that have eroded it. The ascent continues until it turns on the right and climbs steeply.

As from here the way is less risky than that of the ascent:

'Mulas' Mules way:

You take the fork that goes to the right; it is signed and the slope is gentler. The journey lasts, from the base to the (B.I.M. 6) army refuge, between 4 and 5 hours, and 6 hours to reach C.A.J.A. refuge or to the old (R.I.M 26) army refuge.

The refuges can accommodate the following people:

R.I.M.26: (2,450m.), 20 people, and it is like a tin marquee, in poor conditions, with cement floors and no facilities, there is no hot water or kitchen or firewood. So we should take mountain heaters, if you ask for gas heaters like camping gas (garrafa pequeña), the ones that are suitable for mountaineering are the ones that contain propane/butane.

C.A.J.A.: (2,660m.), 10 people, with soil floor, in poor conditions, and no facilities, idem R.I.M.

B.I.M.6: ( 2.350m.), 15 people, cement floor, sheet metal roof, no facilities, idem R.I.M

The use of the R.I.M. 26 and B.I.M 6 refuges is subject to Mountain Infantry Regiment's activities.

The food in the refuges are for emergencies, you should avoid eating them.

MODALITY: Trekking.

LASTING: between 4 and 6 hours.


TIMETABLES: it is a must to depart from the 'Seccional de Guardaparques' (Rangers Station, before 2:00 pm.



  • You should always register at Turbio River Ranger Station before the ascent.
  • You should have a suitable mountaineering outfit (you can rent it in Junín and San Martín de los Andes)
  • You should give notice to the ranger when returning.
  • You should take the waste down with you and, then, throw it away.


  • You should be fit for mountaineering.
  • If you are a beginner you should hire a mountaineering guide's service authorized by National Parks Administration (Administración de Parques Nacionales)
  • You should try the summit only if weather conditions allow you to do so.
  • When you go down, you should avoid doing so a sitting position, because there might be rocks and gaps covered by the snow and you can have blows or/and fractures.

2nd Stage: from the Refuge to the Summit

MODALITY: Trekking on ice

LASTING: 5 to 7 hours.


TIMETABLES: it is important to start the ascent early, between 4 and 5 in the morning, that lets us have enough daylight hours to get to the summit and go back to the refuge. At the same time, the snow is still hard and that will facilitate the use of crampons

From C.A.J.A. we should take the path signed with stakes, or if there is snow, take the nearest plank until you reach the 'canaleta' (gully).

As from there, it is advisable to go up taking the right side edge of the 'canaleta', until you arrive at a rocky wall, you should take the right side to go over it. As from that point, in summer, it is likely to be able to walk on the rocks without crampons In the pre-summit there is snow and there are ice towers that make you take the depression on the left at the last metres.

In cases that you can not reach the peak, due to bad weather conditions, it is advisable not to insist and try again in another opportunity. The summit is just half the journey and although going down is not so demanding for the body, you should avoid running down. A slip can bring about a bad time. A slight sprain in that place will require calling the rescue patrol come to where the injured is, with the consequences and characteristic risks in these rescue operations. If you have managed to drive your crampons successfully on the summit, you should inform your successors that they should take the same care. The ascent conditions vary according to weather and season.


  • Warm clothes (pail - like anorak jacket and a layer to cover the trousers, hat and gloves)
  • Trekking boots (with Vibram sole, knee length if possible), or double boots.
  • Sunglasses with UV filter or specs
