The railway from Curitiba to Paranaguá, opened in 1885, is one of the great mountain railways of South America. The Serra Verde Express now runs the tourist service down from the Curitiba plateau through the Serra do Mar, in and out of long tunnels, over iron viaducts spanning gorges of dense Atlantic forest, and finally onto the coastal flatlands and into Paranaguá's quiet station. The full descent takes about three hours.
The trip can be done as a day return from Curitiba or one-way from Paranaguá. Sit on the right-hand side going down (left going up) for the long valley views. Different classes of service are offered, from basic to a "Great Class" carriage with food and drink included; the basic option sees just as much. Tickets sell out well in advance for weekends and Brazilian holidays.
