Capital of the prosperous southern Brazilian state of Paraná, Curitiba is the gateway to the Serra da Graciosa mountains and the lush rainforests, islands and long beaches around Paranaguá Bay, all reachable on a spectacular mountain train. While most city visitors are in transit, there are a few sites worth visiting to while away an hour or two. Among them is the Oscar Niemeyer Museum, with striking buildings by the celebrated architect. There’s a good choice of hotels in Curitiba, too. These are, for our money, the best – all bookable on Culture Trip.
