The Itatiaia National Park was the first conservation unit created in Brazil in 1937. Serra dos Órgãos as well as the park can also be divided into two areas, due to its vegetation and climate, the upper and lower part. What distinguishes Itatiaia is mainly the huge area of the upper part with its mesothermic microclimate, altitude fields, endemic species and beautiful rocky outcrops. The Itatiaia massif is one of the largest in the world due to its geomorphological process and the peak of the Black Agulhas, with its culminating point at 2791 msnm, is one of the highest in the country. Climbing is one of the great attractions of the region that offers several options for mountaineering as well as for sports and traditional climbing. The lower part has abundant rivers and good waterfalls for bathing, tropical climate of altitude and Atlantic forest. The fauna is rich in this part and it is possible to see different species of birds and mammals such as toucans, jacus, maitacas, quatis and monkey-nails. The Rebouças shelter is the only place to stay overnight in the upper part and therefore it is necessary to schedule in advance.
