Ushuaia, capital of Tierra del Fuego, sits on the Beagle Channel below the snow-capped Martial Mountains. It is the world's main gateway for Antarctic expedition cruises. Most Antarctic voyages start and end here, and Patagonia and Cape Horn itineraries also call.
Ships tie up at the commercial pier on the city waterfront, a short walk from Avenida San Martin's shops and the restaurants serving centolla (king crab) and Fuegian lamb. Popular outings are a Beagle Channel boat trip past sea lion colonies and the Les Eclaireurs lighthouse, the forests and bays of Tierra del Fuego National Park, the hike to Laguna Esmeralda, and the former prison that now houses the Maritime Museum.
