OverviewVolcan Tromen is a stratovolcano in northeast Neuquen Province of Argentina, and is the second highest mountain in Argentine Patagonia after Volcan Domuyo which lies 70km to the NNW. The name Tromen means “soft” in Mapuche and it certainly isn’t very hard to climb. Volcan Tromen is set in the Provincial Park of the same name with Laguna Tromen at its foot. The Laguna is the habitat of a large number of bird species including the black necked swan and the Austral Flamingo. The volcano is part of the Cordillera del Viento however it is quite isolated and dominates the landscape around Chos Malal. The climb can be made in a long day from Laguna Tromen.
It is possible to climb Volcan Tromen in a very long day from the refugio but it is better if you set up a base camp near the lake at the base of the mountain. There is a small puesto there where you can obtain drinking water from a spring. To reach the puesto continue on ruta 37 past the turn off to Refugio Wayle for a couple more kms before heading right on a sandy track, round the laguna to the base of the mountain.
The standard route begins near the puesto on the southeast corner of Laguna Tromen, at 2,150m. Keeping the large dark lava flow always to your right, follow the clear gulley which runs from about 3,800m right down to near the base of the mountain near the lake.
There is a path up this route, sometimes just to the left of the gulley, at other times to the right and at other times in it. This is often indistinct however, and splits into many different branches, making it difficult to follow. To around 3,000m the climb is easy on grassy and sandy slopes, but from this height to the top of the gulley you will find yourself on steep sand, scree or rocks. Some of these rocks are quite loose, so care must be taken.
We climbed when there was no snow around, and it took 5 hours from base camp to the summit and 3 hours to get back.
In summer and autumn when there is no snow on the route there is no water at all, so ensure you take enough for the climb with you from camp.
Red TapeNone. The guardaparque in Refugio Wayle may ask to take your details, but there is no red tape or permits required.
CampingIt is possible to camp at Refugio Wayle and also near the puesto at the southeast corner of Laguna Tromen near which the standard route up Volcan Tromen begins. Camping is not allowed in all parts of Area Natural Protegida Tromen however - there are "no camping" signs along some sections of the shore of Laguna Tromen.
