Les Eclaireurs Lighthouse.

Standing on a barren, rocky islet in the Beagle Channel, Les Eclaireurs Lighthouse is the defining symbol of Tierra del Fuego. Built in 1920, the active, solar-powered beacon is instantly recognizable by its bold red-and-white stripes, contrasting sharply with the dark, windswept southern waters and the dramatic mountain backdrop. While often confused with the "Lighthouse at the End of the World" from Jules Verne's novel—which actually sits further east—this solitary 11-meter stone tower holds its own legendary appeal. Because landing on the islet is forbidden, visitors experience the landmark from the water, usually during catamaran or yacht excursions from Ushuaia that skirt past nearby sea lion and cormorant colonies, offering a classic maritime view of this remote outpost.
