As you sail into Ushuaia, the captain almost always takes you around the picturesque lighthouse at the "end of the world": a beacon for the southernmost city perched on the edge of the Canal Beagle. The port is just two blocks from the main street, leaving you in a central location once you disembark.

Before undertaking the five-minute walk into town, stop at the Tourism Office (right in front of the port), where you can gather information and take advantage of the free Wi-Fi. Most city attractions can be reached on foot, although if you're spending the night here, you may need to take a taxi to your hotel. If you're in Ushuaia only for the day, lace on some good shoes, as the city is built on a hill and requires calves of steel.
