Faro Les Éclaireurs, often mistakenly referred to as the 'Lighthouse at the End of the World', is a prominent landmark in Ushuaia's Beagle Channel, exclusively accessible via guided boat tours departing from the city's port. Visitors cannot land on the island, but tours typically circle it for excellent photo opportunities. These tours, which usually last 2.5 to 4 hours and cost approximately $50-100+ USD, also often include wildlife viewing like sea lions and cormorants. The best time to visit is during the warmer months from October to April when tours are more frequent and weather conditions are milder; winter visits may be limited by colder weather and rougher seas. Dressing in layers is highly recommended due to the windy conditions on the water.
