Paraúna

Parque Estadual de Paraúna (PEPA) is a state park in southwestern Goiás, central Brazil, protecting a rugged Cerrado landscape of sandstone canyons and sculpted rock formations entirely within the municipality of Paraúna. Originally established by Decree No. 5.568 on 18 March 2002 covering about 3,250 hectares, the park was expanded to 4,208 hectares by State Law No. 23.456/2025, strengthening protection of the geological formations and their Cerrado catchment. ^[1] The park's signature features are the Serra das Galés and Serra da Portaria, two sandstone ranges whose formations have been weathered into striking natural sculptures — the most famous being the Cálice de Pedra (Stone Chalice), adopted as the symbol of Paraúna city. Managed by SEMAD, the park combines dramatic geology with intact savanna, making it a priority area for Cerrado conservation in southern Goiás.

The park's Cerrado, gallery forests, and rocky outcrops shelter a diverse fauna characteristic of southern Goiás. Charismatic and threatened mammals include the maned wolf, giant anteater, giant armadillo, puma, ocelot, jaguarundi, and pampas deer, along with smaller carnivores and several armadillo species. Birdlife is abundant across the savanna and forest edges, from macaws and toucans to seriemas, motmots, and a wide range of Cerrado songbirds. Reptiles such as tegus, caimans in the streams, and various snakes occur, and the watercourses support characid fish and armored catfish. Because the park lies among a network of Cerrado remnants in southern Goiás, it functions as an important stepping-stone habitat that helps maintain connectivity for wildlife moving between larger protected areas such as Emas National Park and neighboring reserves.

Vegetation ranges from cerrado sensu stricto on the plateaus to denser cerradão on deeper soils, campo rupestre (rupestrian grassland) on the sandstone outcrops, and gallery forests threading the stream valleys. Iconic Cerrado trees such as pequi, baru, lobeira, sucupira-preta, and ipê grow on the interfluves, while buriti palms line the watercourses. The campo rupestre zones, rooted in thin soils and rock crevices, host specialized plants including Vellozia species, wildflowers, and fire-tolerant herbs and bromeliads adapted to intense sun and periodic burning. Damp microhabitats near seeps and waterfalls support orchids and moisture-loving plants. Seasonal fire is a natural driver here, triggering the flowering of geoxylic subshrubs that survive by storing reserves in underground woody bases — a hallmark adaptation of the Cerrado biome that the park helps conserve.

Paraúna's landscape is carved from sandstones of the Paraná Basin, with formations of Permo-Carboniferous age — roughly 290 million years old — forming the cliffs, canyons, and sculpted rocks that define the park. Long-term wind and rain erosion has shaped the sandstone of the Serra das Galés and Serra da Portaria into distinctive figures likened to a chalice, a turtle, a sphinx, and other forms, with the Cálice de Pedra the best known. ^[1] Elevations range from roughly 690 to 890 meters across plateaus and canyon walls. Red-yellow latosols mantle the flat uplands, while sandy and rocky soils on the outcrops and slopes host the specialized rupestrian plant communities. This sandstone geology, rather than any granite-inselberg or rock-art context, is the park's central natural attraction and the basis for its designation.

The park has a tropical savanna climate with a hot, wet summer from around October to April and a drier, cooler winter from May to September. Annual rainfall averages roughly 1,400 to 1,700 millimeters, concentrated in the height of summer when thunderstorms can rapidly swell the canyon streams. Summer daytime temperatures typically reach the low 30s Celsius, while clear winter nights can fall below 10 degrees under the open sky. The dry season brings intense sun, low humidity, and heightened fire risk, especially in August and September. Waterfalls run fullest during the rains, so the transitional months of April and October are often favored by visitors seeking healthy river flow without peak storm risk. This seasonal rhythm shapes both the vegetation cycles and the practicalities of trail and canyon access.

The Paraúna region of southwestern Goiás was home to Indigenous peoples, including Ge-speaking groups and, later, communities such as the Kayapó and Bororo, before Portuguese colonization advanced in the 18th century in pursuit of cattle pasture and mineral prospects. Colonial and later 19th-century ranching converted much of the plateau to pasture, while the rugged sandstone canyons and rock formations largely escaped intensive land use because of their inaccessibility. The dramatic shapes of the Serra das Galés and Serra da Portaria long attracted local curiosity and admiration, and the Cálice de Pedra formation became so emblematic that the municipality of Paraúna adopted it as its official symbol. The park thus preserves both a natural monument and a landscape woven into local identity, rather than any documented prehistoric rock-art tradition.

Parque Estadual de Paraúna was formally created by Decree No. 5.568 on 18 March 2002, protecting the sandstone monuments of the Serra das Galés and Serra da Portaria together with the surrounding Cerrado biodiversity. ^[1] The park is administered by the Goiás state environmental agency, SEMAD, and forms part of a wider conservation landscape in the region that also includes the associated APA Serra das Galés e da Portaria. In 2025, State Law No. 23.456/2025 expanded the park from 3,250 to 4,208 hectares, with boundaries refined to include additional native vegetation remnants while excluding agricultural areas and road perimeters. Throughout its history the park's focus has been the conservation of its distinctive geology and Cerrado, supported by regulated visitation and scientific study rather than by claims to archaeological sites located in other municipalities.

The headline attractions are the sandstone formations of the Serra das Galés and Serra da Portaria, above all the Cálice de Pedra (Stone Chalice), the natural sculpture that symbolizes Paraúna city, alongside other weathered figures likened to a turtle, sphinx, and more. ^[1] Marked interpretive trails, generally short and easy, wind through native Cerrado between the rock formations, allowing visitors to appreciate both the geology and the savanna flora. Natural pools along the Bonito stream and panoramic viewpoints over the surrounding plateau add further highlights. The dry-season months are considered ideal for trail access, with cooler, more stable conditions. Most routes are well suited to casual visitors, while organized group visits and scientific access require prior authorization from SEMAD, reflecting the park's balance between recreation and protection.

The park lies about 148 kilometers southwest of Goiânia via the BR-060 highway and GO-411, with the entrance roughly 20 kilometers from the town of Paraúna. Entry is free and the park is open daily during daytime hours (6 a.m. to 5 p.m.). Basic infrastructure includes a reception point, picnic areas, and restrooms, while the nearby town of Paraúna offers pousadas, restaurants, and local guide services. ^[1] Visitors should bring water, sturdy footwear, and sun protection, and be prepared for unpaved final road segments that can become difficult after heavy rain. Because trails traverse rocky, sculpted terrain, visitors with limited mobility should plan accordingly. The park's compact scale and free access make it an appealing destination for day trips focused on its geology, viewpoints, and Cerrado scenery.

Conservation at Paraúna centers on safeguarding the distinctive sandstone monuments of the Serra das Galés and Serra da Portaria together with the Cerrado biodiversity and watersheds they anchor. Priorities include controlling invasive grasses, managing wildfire, and maintaining ecological connectivity with neighboring Cerrado fragments, supported by the 2025 boundary expansion under Law 23.456/2025 that enlarged the protected area from 3,250 to 4,208 hectares. Scientific partnerships with universities support biodiversity inventories and fire-ecology research, while community engagement encourages sustainable practices in the buffer zone, including agroforestry and the sustainable use of native fruits such as baru and pequi. Visitation is managed through free but regulated access and permit requirements for group and scientific visits, protecting sensitive rock and rupestrian communities. As droughts intensify, climate adaptation is an increasing focus, given the pressure on both Cerrado vegetation and the region's seasonal rivers.
