This 26 km trail runs north through the Ralco National Reserve from the Chilean National Forest Corporation (Conaf) lodge at Quillaicahue up to the Laguna La Mula mountain lake and beyond. It can only be traversed on horseback with a local guide. It is possible to view a wide variety of local wildlife, both plant and animal, and the trail offers views of Laguna La Mula, Salto Loncotahue waterfall, the Callaqui Volcano (3,095 m.a.s.l), Cerro Ruca Cherrube mountain and the Ralco River. Two local indigenous Pehuenche communities live within the reserve: the Ralco Lepoy community and the Quepuca Ralco community.
