In 1860, the footsteps of the travelling botanist Strobell took him to the valley located at the foot of the Torrecillas Mount. Dazzled by the beauty of the landscape and, making use of his knowledge, he chose a ligneous shrub that Mapuches aborigens called "Coli Mamul" ( Yellow Firewood) to name this region.

From that moment, this valley takes the mapuche name of the Adesmia Pinifolia: Yellow Firewood Valley.

For many years, a dream crossed the valley: the possibility of creating a ski center. Before the construction of the complex, experts worldwide conducted studies, made calculations and designed projects. All of them reached the same conclusion: this was an exceptional area to practice winter sports while its special microclimate, free of rain, was ideal to enjoy outdoor activities during the summer and the rest of the year.

So, with great effort and hard work, on January 20, 1983, the construction of the ski center was begun and on June 16, 1983, the center started operating with 400 beds in 3 hotels. Today, it boats 3047 beds and the prestige of being one of the major hotel complexes of Latin America.
