Description
Bahía Blanca, or "White Bay", is the name given to this many-tendrilled body of water as well as the metro area that sits on it. Technically, it's not a bay but an estuary – a transitional waterway between a river (in this case the Napostá Grande Stream) and its opening to the sea, where saltwater and freshwater mingle to become brackish. The city built on the estuary – just "Bahía" to its 300,000 or so residents – is one of several Argentine ports on the coast of Buenos Aires Province (which, somewhat misleadingly, doesn't include the country's capital city Buenos Aires).
