Fodor's Expert Review Parque do Flamengo
The landscape architect Roberto Burle Marx designed this waterfront park that flanks the Baía de Guanabara from the Glória neighborhood to Flamengo. Frequently referred to as "Aterro do Flamengo," the park contains playgrounds and public tennis and basketball courts, and paths used for jogging, walking, and biking wind through it. On weekends the freeway beside the park is closed to traffic and the entire area becomes one enormous public space. For safety reasons, avoid wandering the park after dark and stick to busy sections even in daylight hours.
