The emerald heart of an oftentimes gray city, São Paulo's Parque do Ibirapuera offers respite from the urban madness among cool, shady trees and mentally-stimulating structures. Running trails, bike paths, and yoga and capoeira sessions let locals and visitors alike keep fit, while a clutch of museums and galleries — such as the museums of Modern and Contemporary Art, all designed by master Brazilian architect Oscar Niemeyer — gives the brain a good workout. The impressive Museu Afro Brasil and fiery Auditório Ibirapuera are two of the park's treasures.
