About Paleotocas de Três Barras
The paleotocas in the Três Barras region are galleries excavated in the sandstone of the Formação Botucatu by megafauna. The set allows learning about a cavity origin different from rock dissolution or the passage of an underground river. The shape of the tunnels and their surfaces constitute the main heritage observed during the visit.
The land is private and access requires authorization from the owners. Municipal guidance is to make the walk with guides accredited in local tourism, since the trail is not signposted for an independent visit. Arrange the entry, the length of the outing and the equipment before leaving. Inside and around the galleries, do not touch the walls, do not carve names and do not collect fragments: reading the markings depends on keeping the sandstone preserved.
