Puerto Williams, located on Navarino Island across the Beagle Channel from Ushuaia, holds the distinction of being the world's southernmost city. In winter, from June to August, this remote Chilean naval settlement of around 2,500 inhabitants enters a period of deep cold and dramatic beauty. Snow covers the jagged Dientes de Navarino mountain range that rises behind the town, the Beagle Channel reflects leaden skies, and the subantarctic forests of lenga and coigüe stand stark and beautiful in their winter state. Days are extremely short — barely seven hours of weak light at the solstice — and the isolation is complete. Yet this is precisely the appeal for those who seek it. Puerto Williams offers an experience of the far south that feels genuinely frontier-like, with a small community of navy personnel, fishermen, and a handful of year-round residents who embody the resilient spirit of Tierra del Fuego. The Museo Martín Gusinde provides insight into the Yaghan people, the world's southernmost indigenous group, while the surrounding wilderness offers winter walks through snow-covered forests. Reaching Puerto Williams in winter requires either a flight from Punta Arenas (weather permitting) or a ferry crossing, both subject to the whims of subantarctic weather. For the intrepid traveler, this is the ultimate end-of-the-world winter destination.
