It is 8 km from the City of Mendoza and is accessed by the Papagayos circuit. This reserve allows us to make a trip to the past of the earth through different rocky outcrops that show us the geological history of the last 200 million years. Its rich biodiversity is due to the fact that it contains species of flora and fauna of a transitional environment (ecotone) representative of the piedmont. The current flora and fauna of the Pedemontano ecosystem are extremely diverse. The explanation lies in the fact that this region is an ecotone, that is, the boundary between two ecosystems or biogeographical regions, one typical of the plain and the other typical of the mountain. During the journey you can see typical species of the plain are carob, chañares, breas, and animals such as the gray gray fox, the rhea, the martineta, and within the species typical of the mountain we find many cacti, the yales, piquito gold, red fox, the cordillerano suri, the condor, the eagle dwells. Both the ñandú and the suri cordilleranos have now disappeared from the reserve that is visited annually by 11,000 people who trek and cycle. Very easy, 2 hours between ascent and descent.
