Argentina shares half of this island territory in the South Atlantic Ocean with Chile. It's a place of oil derricks, sheep, glaciers, wind and waterways. Ushuaia and Río Grande are the two main towns; awesome scenery, wild walks and fishing are the island's main attractions. Argentina's only coastal national park comprises rivers, lakes, forests and glaciers, with great trekking and wildlife-spotting opportunities.

This is a lively and fertile land full of flowers, plants and birds. The Argentine Antarctica, the Islands of the South Atlantic and the Falkland Islands depend on this province. It is only one of the hundreds of islands that form the archipelago that goes from the Magellan Strait to Cape Horn. This is a paradise of mountains with eternal snow, majestic millenary glaciers, shaped-by-the-wind trees, a wide variety of moss that cover the rocks and a great abundance of marine fauna.

Known as the southernmost city of the world, Ushuaia is 3300 km from Buenos Aires. It is located in the southern area of the island, by the Beagle Channel, and surrounded by the Martial Hill, which offers a unique landscape due to the combination of mountains, sea, glaciers and forests. The strange topography of the region created a very picturesque city that combines colors and depressions with the Andes in the background. From the coast to the south there is a superb view of the bay, the peninsula, the Beagle Channel and the Navarino and Hoste islands. The End of the World Museum, also called Territorial Museum, exhibits numerous elements related to the history of the city and its primitive inhabitants. 

In the outskirts of the city stands the old prison of Ushuaia called Presidio y Carcel de Reincidentes. Very dangerous convicts and well known political prisoners made this prison famous. It stopped working as a prison in 1947 and one of its buildings is still kept in its original state. This prison played an important role in Ushuaia's history since all its staff lived in the village and the prisoners contributed with the work of the rest of the inhabitants. At present, the Naval Base Almirante Berisso works here. On top of the Martial Glacier there is an excellent view of the city and its outskirts. The glacier is reached through a lift chair located 7 km from the center.

Leaving Ushuaia to the north, bordering the river that descends from Olivia Mount, symbol of Ushuaia, the road goes through the Andes. The landscape turns into beautiful valleys and mountain ranges such as the Carbajal mountain range or the Alvear chain that extends to the Garibaldi Pass. Among these hills, there are important cross-country ski resorts where different winter activities are carried out such as the Huskies Valley, Tierra Mayor, Las Cotorras and Haruwen. The Garibaldi Pass, 430 m. above sea level, is the highest point of the route where there is a panoramic point that allows the visitor to discover the Escondido Lake, the Petrel Inn and part of the Fagnano Lake.

Going down towards the shore of the Escondido Lake stands the Petrel Inn, located near the most important sawmills: "Lago Escondido", at the beginning of the Milna River, and "Laguna Verde" where a process of industrialization of local wood is carried out. The Fagnano Lake, called Kami by the Indians, is the largest lake of the area. Its long shape from east to west runs parallel to the Beagle Channel and flows into the Pacific Ocean. The nearest town is Tolhuin, located 7 km away to the north. Another lake of the Tierra del Fuego Island is Yehuin, word that means "Woodfire Home" in Quechua. It is located 95 km south of Rio Grande and it is a place of incredible beauty. It belongs to the basin of Fagnano Lake and its waters are only interrupted by the "Roca de los Pajaros" (Birds' Rock), whose name is due to the presence of cormorants (Phalacrocorax) that rest on it. It is also a special place for fishing lovers. 

To the north of Tierra del Fuego, located in a typical steppe landscape, is the city of Rio Grande. It is a center devoted to the exploitation and exploration of oil. In the outskirts of the city, there are numerous estancias devoted to sheep raising. The city is an important communications center thanks to its airport, which operates all year round. From there, a route to the north leads to San Sebastian, where it is possible to cross the border to Chile and then, across the Magellan Strait, reach the continent. Only 12 km to the west of Ushuaia is the access to the Tierra del Fuego National Park, a fantastic natural space where numerous flora and fauna species live together in harmony. 

The park offers a different landscape each season of the year; the flowers are the star attraction in the summer. About 500 species distributed from the sea level to a 700-m altitude have been classified. 30 % of the total surface of the park is occupied by the Andean-Patagonian or Sub Antarctic forest with trees belonging to the family of the Nothofagus: hires (Low deciduous beach tree), Guindos (Evergreen beach tree) and the most important of them: Lengas (High Deciduous Beach tree) as well as some other species in a lower proportion. Due to the diversity of climates and vegetation of this territory, over 200 bird species have been registered including the majestic Condor, known as the King of the Andes and easily seen in flight. In the forest, two mammalian species stand out, both introduced at the arrival of the first settlers: the Rabbit and the Beaver. The latter is the species that caused the greatest impact on the environment, specially in the hydro system, building dams that change the course of the waters. 

The last spurs of the Andes offer a landscape eroded by millenary glaciers, unexplored valleys, winding rivers, hidden canyons, large peat bogs and charming lakes. On the way to the park, the road goes through the Estancia Rio Pipo where the Tolkeyen private tourist area is located. Here, it is possible to taste delicious lamb barbecues, one of the typical dishes of the regional cuisine together with the Centollas (crab). 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 sawmills 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 camping of the Yamanas and Shelkman cultures, called "Rio Ajej", which recreates their customs. In the final part of the journey, along the Canad6n 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. This is 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, with no need to go back to the city.

Sailing across Ushuaia Bay, you can admire an impressing 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. It keeps the history and mystery of old shipwrecks. The preservation of the marine fauna in its natural environment provides a unique scenery. Close to the Bridges Archipelago stands the Birds' Island where, guardians over the rocks, the imperial and Magellan cormorants deceive the visitors with their penguins appearance and live together with a wide variety of marine fauna formed by albatross, huge petrels, noisy seagulls and ducks. Within short distance is the Sea lions' Island, where different species of sea lions rest under the sun. Nearby, stands the Les Eclaireurs Island with its lighthouse, only witness of the sinking of the German ship Monte Cervantes in 1930. 

On the Martillo Island, there is a colony of Magellan penguins that may be watched from the catamarans that offer excursions through the Beagle Channel. Opposite this island is Harberton Bay, on the crystal clear waters of the channel, where stands the Estancia Harberton. It may also be reached from Ushuaia by land. It belongs to the Bridges family and it is the oldest construction of the Island with elements brought directly from England in the 19' century. From Harberton Bay, it is possible to see the Hoste Island (Chile), which Jules Verne chose to place a fantastic republic in one of his novels. 

To the south of the Tierra del Fuego territory, there is a chain of small islands separated by the Beagle Channel. On the largest of those islands, Navarino Island (Chile), is Port Williams, a village used as departure point for expeditions in the southern extreme of the continent. The Falkland Islands are located within the territorial waters of the Argentine Sea in the Atlantic Ocean.
