Blessed with over 2 million sq. m (22 million sq. ft.) of green space, São Paulo's version of Central Park offers quite a bit to see and do. You can wander the paths beside pleasant lagoons or rent a bicycle (R$6 per hour) and cycle the pathways. Every Sunday morning there's afree outdoor concertin the park's Praça da Paz. Sunday from 10am to 4pm you can take advantage of the Bosque de Leitura, a kind of free outdoor lending library that lets you borrow magazines or books (including many in English) to read in the park for the duration of day. In the corner near Gate 3 there's the Museum of Modern Art. Just nearby there's the excellent Afro-Brazil Museum and the OCA Auditorium, a flying saucer-shaped building that often hosts traveling art exhibits. Allow half a day.
