Terra Ronca State Park, located in northeastern Goiás, was created in 1989 to protect one of the largest and most spectacular cave complexes in Latin America. The park was established to preserve the region’s unique limestone formations, especially the imposing caves and underground rivers that attract speleologists and tourists from all over the world. Covering an area of approximately 57,000 hectares, the park is home to impressive biodiversity and several ecosystems typical of the Cerrado biome. The name “Terra Ronca” comes from the sound of the underground waters that reverberate in the caves, creating a characteristic “rumble.” Today, the park is managed by Goiás’ Secretariat of the Environment, and although access to some areas is restricted to protect the caves’ fragility, it welcomes tourists and researchers interested in exploring its natural wonders. The main attraction is the Terra Ronca I cave, known for its enormous entrance portal, which rises to about 96 metres, as well as numerous other caves, rock formations, and underground rivers.
Terra Ronca State Park is a natural heritage site of immense significance to Brazil and the world due to the uniqueness of its cave complex, underground rivers, and rock formations. It plays a vital role in preserving the Cerrado’s ecosystems, protecting various species of flora and fauna, many of which are endangered. Besides its environmental importance, the park is a key player in the sustainable development of local communities, promoting ecotourism and adventure tourism. Its conservation ensures the protection of essential water resources for the region and contributes to scientific research and environmental education.
Entrance to Terra Ronca State Park is free; however, to visit the caves and engage in guided activities, it is necessary to hire accredited guides who ensure visitor safety and environmental preservation. Tour costs vary depending on the duration and complexity of the cave to be explored, with packages usually including local transportation and safety equipment such as helmets and flashlights. It is recommended to schedule visits in advance, especially during holidays and peak season. Although the park is public, access control is important to prevent damage to sensitive areas and ensure an enjoyable experience for all.
When visiting Terra Ronca State Park, prepare adequately. Wear light, durable clothing and comfortable shoes with good grip, as the trails can be slippery and the caves humid. Sunscreen, a hat or cap, and insect repellent are essential to protect against the elements. Always carry sufficient water to stay hydrated, as well as light snacks such as fruits and cereal bars, as food facilities are limited. Respect signage and instructions from guides, staying on designated trails and areas to minimise environmental impact. Do not feed the animals and keep your distance from local wildlife. Remember to take all your rubbish with you and use the available bins. Contribute to the park’s conservation by avoiding the removal of any natural or historical material.
The best time to visit Terra Ronca State Park is during the dry season, from April to September, when the weather is more stable and the trails and caves are more accessible. During the rainy season, from October to March, river levels can rise, making some caves harder to access and the trails more challenging. In the dry season, conditions are ideal for exploring caves and waterfalls, providing a safer and more comfortable experience. However, even during the rainy season, the park offers an impressive natural abundance, with dense vegetation and swollen rivers, ideal for those seeking a more intense connection with nature.
To reach Terra Ronca State Park from Europe, the best entry point is Brasília International Airport (BSB). From there, the journey continues by road to São Domingos in Goiás, the base city for exploring the park. The distance between Brasília and São Domingos is about 400 km, and the trip can be made by car or bus. To access the caves, it is recommended to hire local guides who offer suitable transportation for the dirt roads leading to the park’s main entrances. The region's infrastructure is simple but functional, offering an authentic and immersive experience in the Brazilian Cerrado.
