Sure, it may feel like the end of the world here in the US, but in Argentina, it actually is the end of the world. Ushuaia, located at 55 degrees south latitude, is the southernmost town on earth. The picturesque town sits on the the shores of the Beagle Channel, one of the three navigable passages around South America between the Pacific and Atlantic Oceans, and is surrounded by the Martial mountain range, chock full of glaciers. It's a popular tourist destination from which to explore Tierra del Fuego, the embarkation port for boats to Antarctica, and the end point (or beginning) of the Pan American Highway that begins in Prudhoe Bay, Alaska. You'll need plenty of alfajores for that road trip!
If you want to see the penguins, seals, and orcas (who doesn't?), you can take the End of the World Train to Tierra del Fuego National Park, which features some of the most dramatic scenery nature can offer. Or visit the End of the World Museum where Ushuaia's history as a Yámana, English, and Argentine settlement, including its years as a prison colony, are on display. Choo choo!
