Hike in the Valdivian Rainforest to one of the most beautiful and hidden spots of Lanin National Park. We will go with the vehicle from San Martin de los Andes to Hua Hum, on the west end of Lácar Lake. Crossing Hua Hum River we will continue to Queñi Lake, where we will leave the vehicle to start walking by the west side of the lake. As we progress, we will notice how the vegetation turns even denser and the humidity higher; we are entering the Valdivian Rainforest a true “cold jungle” made of enormous Cohiue trees and an extremely rich undergrowth. In about an hour and a half we will leave the lake behind and arrive to Chachín River, which feeds Queñi Lake. Just a few meters more and we will find the thermal springs, with the hot water springing from the rocks to a few natural pools. Do not expect any luxuries here, but taking a thermal bath surrounded by this wild environment is incomparable. After the bath we will have lunch and take our way back to San Martín de los Andes.
