Estrada da Graciosa Serra do Mar Atlantic Forest Circuit

Built by slaves in the 1870s as the Graciosa Railroad route, this cobblestone and dirt track winds 30 kilometers through some of Brazil’s last intact Atlantic Forest. The route drops 900 meters from the Paraná plateau through dense cloud forest, past abandoned railway tunnels and stone bridges, with the highlight being the historic Vila Velha sandstone formations and the spectacular Marumbi Peak viewpoint overlooking the coastal plain.

This is an easy to moderate route suitable for most high-clearance vehicles, though wet cobblestones can be extremely slippery. The forest receives over 2,000mm of rain annually, so avoid the wettest months of December-February when landslides are common. No permits required, but fuel up in Curitiba as services are limited. Multiple camping spots exist near the Marumbi State Park headquarters. The payoff is driving through one of Brazil’s most biodiverse ecosystems with excellent birdwatching and waterfall access.
