Perched on the southernmost tip of South America, it’s no wonder Ushuaia is referred to as the ""End of the World."" The windswept town’s icy proximity to Antarctica magnetizes tourists, who are drawn to the penguin colonies of Isla Yecapasela, glaciers, and Martial Mountains. Boat trips and epic hikes reveal the pristine beauty of the Argentinean city, part of Patagonia’s Tierra del Fuego National Park, which is best appreciated in its entirety on an End of the World train ride. A scattering of quaint hotels, souvenir shops, and restaurants serving the local speciality spider crab make the town a comfortable place to rest between adventures.
