Buenos Aires sits on the south side of the Río de la Plata estuary, which feeds into the Atlantic Ocean. A confluence of the Uruguay and Paraná Rivers, it extends for approximately 180 miles.

The name means River of Silver, although it is usually translated as River Plate. It kicks up a good deal of sediment, which can make it appear reddish-brown in colour.
