Ushuaia: the city at the end of the world in the land of fire. Backed by the rugged mountains and looking out on to the Beagle Channel, Ushuaia sits close to the wild reaches of the Tierra Del FuegoNational Parkand is popular for hiking and skiing. But it’s the city’s role as launching pad for Antarctic expeditions that gives Ushuaia its edge-of-the-map romance, the icebreakers mingling with cruise ships, excited passengers-to-be walking waterside to catch a glimpse of their berth. Setting sail from Ushuaia’s harbour is a spine-tingling thrill, alive with anticipation. The Beagle Channel soon surrounds your ship, gulls your escort as you head for sea – wave goodbye to Argentina, and let your Antarctic adventure begin.
