The story that haunts this land
Your journey begins at the Chapada dos Guimarães National Park, a jewel of Brazilian natural heritage, officially established on September 4, 1985. Here, in the state of Mato Grosso, red sandstone cliffs, remnants of an ancient Mesozoic ocean floor, stand tall. The park, covering 32,920 hectares, is an open-air geology lesson. From the entrance, you are confronted with the scale of deep time, where each rock tells the story of millions of years of transformations. Access is free for pedestrians, allowing you to appreciate the immensity of this landscape without constraint.
A short walk from the main entrance, via Rod. Emanuel Pinheiro Km 50, stands the majestic Cachoeira Véu de Noiva, an emblematic waterfall of Chapada dos Guimarães. Its 90-meter drop over the red cliffs offers a striking perspective on the continuous erosion that sculpts the region. The Véu de Noiva viewpoint, accessible by a sometimes demanding trail, is the ideal observation point to contemplate this natural wonder. This site is often the prelude to the famous Circuito das Cachoeiras, a section of the park where water reigns supreme, but its splendor deserves prolonged contemplation.
The Circuito das Cachoeiras, a 6 km self-guided trail, is a direct immersion into the abundant water features of Chapada dos Guimarães. You will discover wonders such as Cachoeira das Andorinhas, 30 meters high and featuring a natural pool. Access to this circuit is limited to 150 people per day from 8:30 AM, highlighting the fragility of this ecosystem. The hike, exposed to the sun, takes approximately 2.5 hours without swimming breaks. Even in September, the water remains cool and invigorating, offering a contrast to the heat of the Centro-Oeste.
Further along the route, Cidade de Pedra (City of Stone) reveals unique geological formations, an eloquent testament to the oceanic past of Chapada dos Guimarães. These red sandstone structures, dating from the Mesozoic, seem to have been carved by giants. Although often explored on 4x4 tours, your walking itinerary will allow for a more intimate approach to these monoliths. Exploring these formations will remind you that Brazil's natural heritage is a succession of giant sculptures, each with its own millennial narrative.
Your adventure ends, but the spirit of Chapada dos Guimarães remains. You have explored an ecosystem where time is measured in geological eras, from red sandstone cliffs to rushing waterfalls. This circuit has allowed you to understand the importance of the Parque Nacional 1985 and its role in preserving this exceptional Brazilian natural heritage. Every step in the Brazilian Centro-Oeste has brought you closer to the primordial forces that shaped this land, leaving an indelible mark of discovery and respect for nature.
