Serra da Canastra: Cerrado Plateau, Waterfalls, and the Cradle of the São Francisco

Serra da Canastra National Park protects a high Cerrado plateau in southwestern Minas Gerais, Brazil, where grassy tablelands give way to cliffs, waterfalls, and river valleys. Created in 1972 to safeguard the headwaters of the São Francisco River, the park lies on the divide between that river system and the Paraná basin, and it is one of the best places in Brazil to see maned wolves and giant anteaters in open country.

Geographic Setting

The park occupies the Canastra Mountains in the southwest of Minas Gerais state, north of the Rio Grande, within the Cerrado biome. It spreads across six municipalities: São Roque de Minas, Vargem Bonita, Capitólio, São João Batista do Glória, Delfinópolis, and Sacramento. The range belongs to the Brazilian Highlands, and its signature landform is the chapadão, a broad flat-topped plateau with treeless grass fields on top. The name canastra means a trunk or chest, a nod to that box-like profile. Two massifs, the Serra da Canastra and the Serra das Sete Voltas, flank the Cândidos valley.

Park History and Boundaries

The federal government created the park by Decree 70,355 on April 3, 1972, with a decreed area of roughly 198,000 hectares (1,980 square kilometers, or 764 square miles). Most of that land stayed in private hands, because the government never bought it. By 2016, only about 70,000 hectares (700 square kilometers, or 270 square miles) had been regularized, with former owners compensated, and ICMBio, the federal conservation agency, now reports that more than 99,000 hectares (990 square kilometers, or 382 square miles) are consolidated in federal possession. Residents who were never compensated have fought to keep their farms and cattle, and a provisional court ruling once allowed them to continue raising livestock inside the park, a decision ICMBio said it would contest.

The Headwaters of the São Francisco

The park was created above all to protect the historic source of the São Francisco, which rises on the Chapadão da Canastra and runs about 2,800 kilometers (1,740 miles) to the Atlantic. Its first great drop is the Casca d'Anta waterfall, which falls 186 meters (610 feet). Later surveys placed the river's geographic source, the point farthest from its mouth, in the Samburá River basin near Medeiros, just outside the park boundary, although the Canastra remains the river's cultural and historical cradle. The plateau is also a divide: other streams drain toward the Paraná system, including tributaries of the Rio Grande, which makes the park a nursery for rivers flowing in opposite directions.

Terrain and Climate

Elevations in the park range from 750 to 1,490 meters (2,460 to 4,890 feet), and the highest peaks approach 1,500 meters (4,900 feet). Cliffs, gorges, and rock formations such as the Garagem de Pedras and the Curral de Pedras break up the plateau, and waterfalls, including Casca d'Anta and Rasga Canga, drop from its edges. The region's geology and its diamond-mining history have made it a focus for geotourism studies. The climate is that of the Cerrado highlands, with a wet summer and a dry winter.

Vegetation

Open grassland and rocky fields cover the plateau, while riparian forests follow the streams and fill the valleys and lower elevations. This mosaic of habitats, typical of the Cerrado, supports wide views of wildlife in a landscape where animals can be seen at a distance.

Wildlife

The Canastra is a stronghold for large Cerrado mammals. The maned wolf (Chrysocyon brachyurus), giant anteater (Myrmecophaga tridactyla), giant armadillo (Priodontes maximus), pampas deer, and bush dog share the grasslands with the cougar (Puma concolor), oncilla (Leopardus tigrinus), ocelot (Leopardus pardalis), colocolo (Leopardus colocolo), and Neotropical otter. Birdlife includes the crested caracara (Caracara plancus), king vulture, toco toucan (Ramphastos toco), and the Brazilian merganser (Mergus octosetaceus), a rare diving duck that nests along the park's clear rivers. The frog Phyllomedusa ayeaye is also among the protected species.

Visiting the Park

Casca d'Anta is the park's best-known attraction and has its own entrance gate, reached by road from São José do Barreiro. Walks to viewpoints, waterfall pools, and wildlife-watching stops on the Chapadão da Canastra fill most itineraries, and ICMBio now licenses commercial tourist transport within the consolidated areas. Tourism has become a second economic pillar for the surrounding towns, alongside ranching and farming.

Why the Canastra Matters

The Serra da Canastra protects the birthplace of one of Brazil's most important rivers, a rare block of open Cerrado, and habitat for several threatened animals. Its greatest challenge is not wilderness but land: until the remaining private holdings are resolved, more than half of the decreed park exists mainly on paper.
