Puerto Madero, also known within the urban planning community as the Puerto Madero Waterfront, is a barrio (district) of the Argentine capital at Buenos Aires CBD, occupying a significant portion of the Río de la Plata riverbank and representing the latest architectural trends in the city of Buenos Aires. Puerto Madero is a nice neighborhood to lounge in one of many parks, ride a bike and perhaps dine on the waterfront, but it’s not distinguished for its abundance of touristic sights.
