Puerto Williams, the southernmost town in the world, is a gateway to Cape Horn and the Antarctic. It’s well worth spending time here to really get to grips with the place. Visit the Martin Gusinde Anthropological Museum to explore the stories of the Yaghan people, the original inhabitants of the region. Explore the Naval Base for a glimpse into the town’s military and navigational significance. While nightlife here is limited, the few bars and communal spaces often host lively conversations among adventurers, sailors, and researchers.
