Terra Ronca State Park, Cave network and conservation area in São Domingos, Brazil.
Terra Ronca is a large protected area in northeastern Goiás featuring limestone rock formations, flowing rivers, and extensive cave networks. The site contains multiple cave systems with underground passages and waterways carved naturally through the rock over thousands of years.
The Brazilian government established this protected area in 1989 to preserve the karst landscapes and natural features of the São Domingos region. This recognition acknowledged the geological and ecological importance of the cave systems and underground ecosystems.
The park holds meaning for local people as a place where guided cave expeditions help visitors connect with the dramatic limestone landscape. Families and groups use these tours to experience the underground world and develop a deeper appreciation for the region's geological character.
You must register at the park entrance and hire a certified guide to explore the cave systems safely, as conditions change with the seasons. Bring waterproof gear and prepare for uneven ground and underground passages with varying temperatures.
The area contains Seu Ramiro cave, which features the largest natural cave entrance in Brazil alongside intricate underground waterways. This massive opening is visible from a distance and marks a remarkable geological landmark within the region.
