Rio Gallegos is the capital of Santa Cruz province in Patagonia, sitting at the mouth of the Gallegos River where it meets the Strait of Magellan. It is primarily a transit city — most travellers pass through on their way to El Calafate and the Perito Moreno glacier, or continuing south to Tierra del Fuego. That said, it's a perfectly functional place to spend a night and has a certain austral character to it.
The city has a frontier feel: wide streets, low buildings, and strong winds that sweep in off the Atlantic. The main square, Plaza San Martín, is tidy and pleasant, flanked by the cathedral and the provincial government buildings. The Museo Regional Provincial has a decent collection of Patagonian flora and fauna, including guanaco and rhea specimens. For those with time, the coast road out toward the Cabo Vírgenes lighthouse offers dramatic views and a large Magellanic penguin colony.
