On Feb xxx ??? We came to Ushuia by plane from Puerto Iguazu. In Argentina we visited Buenos Aires, Puerto Iguazu and Punta Tomba. These place I visited already in 2011. Please see Patagonia Trip report.
Usuhuia is the capital of the southernmost argenitinan province called Tierra del Fuego, Antartida e Islas del Atlantico Sur. Ushuiaa is a sliver of steep streets and jumbled buildings set between the Beagle Channel and the snowcapped mountain called Martial range. There are a lots shops offering outdoor activities: hiking, sailing, skiing, kayaking etc.
