A short but challenging trek just a few minutes away from San Martin de los Andes. We will go with the vehicle to the start of the trail, in an area called by the Mapuche native community Pampa del Trompul. Soon we will start going up by the steep slopes covered by dense Patagonian forest. As we gain altitude the vegetation turns shorter which will us to get great views of the Lacár Lake valley. Soon we will pass the timberline and reach a rocky area that will lead us the summit, made of red rocks that are the remains of an old lava flow. From the top, at 1,778 m, we will have a great view of the south face of Lanín volcano, with the Lolog Lake valley on one side and the Lácar Lake valley on the other.
