The main attraction of the smallest Brazilian National Park is the Gruta de Ubajara (Grotto). In the region you can also find waterfalls and enjoy different forms of vegetation from scrub until the humid forest. The Gruta de Ubajara is formed of limestone shaped by groundwater. To go down to the main mouth of the grotto there are two options: take the trail Ubajara - Araticum or take the chair lift to the lower part of the plateau. The cave has 1,120 meters long, of which 420 are illuminated artificially and open to visitors. The route inside the cave begins in the Sala de Imagem (Image room), through the Corredor das Maravilhas (Corridor Wonderland) and through the rooms of the Rosa (Rose), the Cortinas (Curtains), the Retratos (Portraits), Seios (Breast), Índio (Indian) and Presépio (Crib). The Cachoeira do Cafundó (Outback waterfall) is located in the Riacho Bela Vista is a tributary of the Rio Ubajara. Before the biggest drop, a natural pool is formed which is a good opportunity to cool off from the heat.
