The town increased in size as a Chilean naval base and now has grown to include several small supermarkets, a handful of restaurants, a bakery, bar and a museum. Puerto Williams is sometimes considered the southernmost city in the world, a title that is disputed by the larger Ushuaia, located on the opposite, northern side of the Beagle Channel in Argentinian territory.
Daily flights run from Punta Arenas to Puerto Williams throughout the year.
There's a secluded all-inclusive lodge called the Lakutaia that's a perfect base if you'd prefer to explore from comfort.
