Sitting at the End of the World, Ushuaia is actually a reasonably comfortable and strikingly beautiful part of the world. With tremendous natural beauty in the lands and mountains around it, it's also a quaint little town. The downtown being filled primarily by tourists and those serving them, from the looks of things.
Walking around town I saw some nice murals on the walls, really adding some local flavor. Once the realm of Selk'nam and Yámana Indians, they've all but been wiped out now. The Selk'nam are considered extinct as a tribe, but a small number of Yámana are still around today, on the Chilean side of the border.
