Dramatic, fantastical, otherworldly—this is the end of the world, for real. Positioned at the most southern tip of Argentina, this memorable port town is cradled between pristine—and towering—Martail mounts landscapes. And it's accessed by the picturesque Beagle Channel, named for Darwin’s famed vessel. Ushuaia is the capital of the Tierra del Fuego region, which is best described as a spectacular collection of superlative natural wonders. It’s a veritable kaleidoscope of glaciers, lakes, snow-capped mountains, dense forests and wind-swept plains spread across an archipelago of rugged islands. The town itself is a maze of streets lined with low-slung buildings that all seem to meet at its heart—and doorway to the world—the port. Founded in 1884, the far-flung spot welcomed missionaries, gold prospectors and naval officers, before becoming known primarily as a penal colony. After its closure under the infamous Argentine leader Perón, the large jail has been reconfigured to house a museum complex. Don't miss a chance to taste the marquee dish—local king crab.
