Ushuaia
Ushuaia stretches as a narrow strip along the northern shore of the Beagle Channel, squeezed between the water and the mountains of the Sierra Martial. The city owes its origin to a prison: From 1902, prisoners built the Presidio, which was in operation until 1947. Today it houses the Museo Marítimo y del Presidio with exhibitions on the penal colony, maritime history, and Antarctica.The most popular excursion is a boat trip on the Beagle Channel to the islands with sea lions and seabirds and to the red-and-white Les Eclaireurs Lighthouse. Approximately twelve kilometers west lies the Tierra del Fuego National Park. The End of the World Train also runs there, a narrow-gauge railway on a section of the former prisoner's railway, which prisoners used to transport wood from the forests. Ushuaia is also the main departure port for cruises to Antarctica.
