The French-inspired Botanical Garden of Curitiba is one of the Brazilian city’s most popular attractions, its colorful flowers, ponds, paths, and art nouveau greenhouse creating a sweet-smelling fairyland. After a floral stroll, continue to explore Curituba’s lovely landscapes at Parque Estadual de Vila Velha and Parque Tanguá. Visit the Museu Oscar Niemeyer, a celebration of the architect’s bold, abstract works, then enjoy a performance at the marvelous Ópera de Arame, built to look like it’s fashioned out of wire.
