#1. Ushuaia
A busy port and adventure hub, Ushuaia is a sliver of steep streets and jumbled buildings below the snowcapped Martial Range. Here the Andes meets the famed Beagle Channel in a sharp skid, making way for the city before reaching a sea of lapping currents.
Ushuaia takes full advantage of its end-of-the-world status, and an increasing number of Antarctica-bound vessels call into its port. The town's mercantile hustle knows no irony: there's a souvenir shop named for Jimmy Button (a Fuegian native taken for show in England) and the ski center is named for the destructive invasive castor (beaver). That said, with a pint of the world’s southernmost microbrew in hand, you can happily plot the outdoor options: hiking, sailing, skiing, kayaking and even scuba diving.
Tierra del Fuego’s comparatively high wages draw Argentines from all over, and some locals lament the lack of urban planning and loss of small-town culture.
