At Valle Nevado during the summer you might be able to catch a glimpse of the region’s flora and fauna, such as:
The culpeo fox (Lycalopex culpaeus), also called the red fox, is the second-largest living canid in South America, surpassed only by the maned wolf. Both the legs and the head are reddish; the belly, neck and mouth, white; and the back, gray striped black. The tail is mostly gray, which turns black toward the tip. It feeds on rodents, hares, birds and lizards, and to a lesser extent on plants and carrion.
And particularly at Valle Nevado it is common to observe:
The Andean condor, a species of bird that lives in the Andes mountain range as well as the adjacent coastal mountains of the Pacific. It is the largest non-marine bird on the planet. Its name comes from the Quechua Kuntur. It is a large black bird, with white feathers around the neck and in parts of the wings. The head has no feathers and is red, being able to change its shade according to the emotional state of the bird. Unlike most birds of prey, the male is larger than the female. It is a scavenger bird. Adults reach up to 142 cm in height, and from 270 to 330 cm in wingspan.
