Courchevel is the name of a ski area located in the Savoie region of the French Alps, and part of Les Trois Vallées, the largest linked ski area in the world. Courchevel has an airport (Courchevel Airport) and a highway linking it with the rest of the world. The original resort was planned during the Second World War with a study in 1942 by the Vichy regime and in a doctorate by the town planner Laurent Chappis. Chappis was a natural choice to direct the development of the resort in the immediate post war years. Courchevel 1850 was significant as it was the first resort in France to be constructed from scratch rather than based around an existing village. It therefore served as an open air laboratory of ideas.

Courchevel also refers to the towns of Courchevel 1300 (Le Praz - the original village), Courchevel 1550, Courchevel 1650 (Moriond), and Courchevel 1850, which are named for their altitudes in metres. The highest point in Courchevel 1850 is in fact only 1747 meters, the name was chosen for marketing reasons to compete with arch rivals Val d'Isère. The Courchevel valley also includes the town of La Tania, built as competitors accommodation for the 1992 Winter Olympics in Albertville. Le Praz hosted the Olympic ski jump in that year.There was a ski Jump in Courchevel 1850 on the snowfront however it was removed recently due to safety precautions.

Courchevel's airport also has a certain degree of infamy in the aviation industry as home to one of the shortest runways in the world, with a length of 525 metres and a gradient of 18.5% in order to help slow landing aircraft. The airport has a dangerous approach through deep valleys which can only be performed by specially certified pilots. On landing there is no go-around procedure, as most of the worlds airports have - there is merely a very steep hill which has seen a few accidents since the airport first opened. Larger propeller aircraft such as the Twin Otter and Dash 7 (carrying up to 70 people) have been regular users of the airport over the years, but have since been phased out of use and smaller Cessnas and helicopters are often seen sitting on the tarmac nowadays.

Courchevel's couloirs are renowned as some of the most difficult black runs in the world.

Courchevel's sister city is Park City, Utah, USA.

Courchevel has one of the largest bases for ski instructors and other seasonals due to the size of the three valleys area.

Since the mid-2000s, Courchevel has become the ski resort of choice for wealthy Russian elites, and its name has become synonymous with "winter playground of the rich and famous" in Russia.

Olbia (Sardinian: Terranoa, Gallurese: Tarranoa), is a town of approximately 51,000 inhabitants in northeastern Sardinia

Called Olbia in the Roman age, Civita in the Middle Ages (Giudicati period) and Terranova Pausania before the 1940s, Olbia was again the official name of the town after the period of Fascism. It is the economic centre of this part of the island (commercial centres, food industry) and is very close to the famous Costa Smeralda tourist area. It is an administrative capital (together with Tempio Pausania) of the province of Olbia-Tempio, operative since 2005.

Olbia (the name is of Greek origin) is very ancient and was possibly founded by the Greeks, according to a local legend. It contains ruins from Phoenician and Carthaginian settlement to the Roman Era, when it was an important port, and the Middle Ages, when it was the capital of the Giudicato of Gallura, one of the four independent states of Sardinia.

Olbia is the main connection between Sardinia and the Italian peninsula, with an airport (Olbia - Costa Smeralda), a passenger port (Olbia-Isola Bianca), and a railway to Porto Torres and Cagliari. There is an expressway to Nuoro and Cagliari (SS131) and national roads to Sassari (SS199-E840), Tempio Pausania (SS127), and Palau (SS125).
