Anfiteatro do Aterro do Flamengo

Tucked inside the iconic Aterro do Flamengo — the world's largest waterfront urban park — this open-air amphitheater hosts concerts, cultural events, and performances against a stunning backdrop of Guanabara Bay. The setting alone is worth the trip, with the park stretching nearly 1.2 km of reclaimed land between Downtown Rio and Botafogo. Check local listings before you go, as the space comes alive during Rio's many festivals and free public events.
