Classic Mountaineering/ Ski mountaineering in the Spring


At 3777 meters, Volcan Lanin is one of the highest volcanoes in Patagonia’s “Ring of Fire”. This beautiful volcano is the namesake for Argentina’s Lanin National Park.  Lanin has that perfectly aesthetic volcanic cone shape. The south and east faces of Volcano Lanin are glaciated, but the classic route on the north face is over volcanic rock and snow. (Remember, we’re climbing in South America where the North Faces of the Andes Mountains get more sun!)

With 2500 meters of solid climbing, our mountain guides spread out the ascent of Volcan Lanin in 2 days of activity staying in a rustic mountain hut in between. From September to October we recommend doing this trip with alpine ski gear.  Depending on the year, sometimes spring conditions allow ski mountaineers to put their skis on right at the base of the volcano. During the South American summer, December through April, Volcan Lanin is a beautiful hike/climb on volcanic terrain.

Along the climb, you may see many species of flora, such as the Araucaria trees, “Monkey Puzzle” trees, that are not found elsewhere in Argentina.  These special trees are living fossils, their cones have been found in Patagonia dating back to the Jurassic Period.


Day 1:
Your mountain guide can pick you up in San Martin de los Andes or Junin de los Andes, Argentina, or you can drive with us from our base in Bariloche, Argentina.   From the foot of the Lanin Volcano, we start hiking through a forrest, which quickly gives way to volcanic terrain, dark earth and lava rock. Tree line is at a higher altitude on the surrounding mountains, but the flora has yet to return completely to the volcano. During the entire day we will have excellent views of the surrounding Andes Mountains.

Early in the season we will be hiking or skinning on snow at a lower elevation.  There are three mountain huts between 2400 and 2600 meters on the North Face of Lanin.  Depending on conditions, your mountain guide will take you to the appropriate hut and prepare a nice, hot meal.

Night in bivouac hut.

Approx. 7 km with 1400 meters elevation change in 6 hours of climbing.
Day 2:
Because of Volcan Lanin’s perfect cone shape, the climb to the summit is on a gradual slope that becomes steeper as we gain altitude.  In the spring, the terrain is a nice steady climb on snow/ice, that we climb with crampons and wait for it to corn up to ski down. In the summer, we hike mostly on volcanic scree and some steep snow and ice at the top.

The views from the summit of Volcan Lanin are amazing!  The blue waters of the Patagonian Lakes District below, and the Andes Mountains all around!  You can see some of the other volcanoes we climb in the Ring of Fire such as Chile’s Volcan Villarica, Volcan Lonquimay, and Volcan Llaima.

Depending on conditions and fitness level of the clients, we can return to the mountain hut, or have a long day of activity and descend all the way to the base of the volcano and stay the night in Junin or San Martin de los Andes.  Usually, our mountain guides climb the Lanin Volcano with clients in 2 days, but it is important to have a 3 day itinerary for weather and stamina.

The descent of the volcano on skis takes us from the summit down to 1200 meters, giving us a 2500 meter ski run!  Lanin is definitely the best volcano to ski in Patagonia’s Ring of Fire!

Approx. ?? km with 1200 meters elevation gain in 6-7 hours of climbing.
Day 3:
We descend to the base of Volcano Lanin and your mountain guide will take you back to one of the nearby towns of Junin de los Andes, San Martin de los Andes, or Bariloche.
