Right after we arrived to Ushuaia we took a tour to Tierra del Fuego National Park.
By the Pipo River, in a outstanding place surrounded by mountains, stands the station of the Train of the End of the World. It belongs to the Ferrocarril Austral Fueguino (Southern Railway). It is a small train with capacity for 36 passengers that goes into the National Park with several intermediate stops in different panoramic points. The train uses the original terreplein of the old small train that worked until 1947 and that transported prisoners from Ushuaia's jail to the saw-mills where they worked daily. The steam trains have been specially designed and built in Argentina for this railway. The train goes through the Pipo River across the Quemado Bridge and makes its first stop at the De la Macarena Cascade. Here, you can see the reconstruction of the Indian campings of the Yamanas and Shelkman cultures, called "Rio Ajej", which recreates their customs. In the final part of the journey, along the Canado del Toro, there is a tourist circuit and 4.5 km from the departure point, you can either choose to continue the visit of the park by bus or to return to the station by train without stops. One of the outstanding parts of the park is the Lapataia Bay, the final point of the only road that goes from Buenos Aires to Ushuaia, 3300 km away. Here, it is sometimes possible to embark and to combine the tour of the National Park with the navigation through the Beagle Channel.  Sailing across Ushuaia Bay, you can admire an impressive view of the city and the mountain range that surrounds it. At the end of the bay, the Chico Pass indicates the entrance to the mythical Beagle Channel with its history and mystery of old shipwrecks.

The southernmost railway station

Beagle Channel

Trending east–west, is about 150 mi (240 km) long and 3 to 8 mi wide; it separates the archipelago's main island to the north from Navarino, Hoste, and other smaller islands to the south. At its western end the channel splits into two branches that encircle Isla Gordon. The eastern portion forms part of the Chile–Argentina border, while the western portion lies entirely within Chile. The three islands at the channel's eastern end, Picton, Nueva and Lennox islands, were the subject of a territorial dispute between Chile and Argentina that began in the 1840s and which almost led to war between the two nations in 1978. The dispute officially ended on May 2, 1985, when a treaty awarding the three islands to Chile went into effect between the two countries. The Beagle Channel was named for the British ship Beagle, in which Charles Darwin explored the area (1833–34).

Ushuaia

 - is the capital of Tierra del Fuego provincia, Argentina, on the Beagle Channel. It lies on the main island of Tierra del Fuego Archipelago at the southern tip of South America.

The site was first settled by Wasti H. Stirling, an English missionary, in 1870. In 1884 an Argentine naval base was established, and in 1893, after the archipelago was partitioned between Argentina and Chile, Ushuaia was declared a city. Lumbering, sheep raising, fishing, and trapping are the city's principal economic activities. Ushuaia has the distinction of being the southernmost city in the world.
