Geneva is part of the Canton of Geneva, the smallest: 282 km2. It is an enclave surrounded by French territories (department of Haute-Savoie in the south, Ain in the north). Its border is 107.5 kilometres long but only 4.5km long with the Swiss confederation. The link with Switzerland is assured by a thin land linking Geneva to the Canton of Vaud, along the Lake Geneva (the small part of the lake, that is part of Geneva, is called Petit lac).
Switzerland is a mountainous country, with 3 natural chains: Alps, Middleland (or Mittelland) and the Juras. Numerous and wide valleys run within this area of rough climate, carved by the icy periods thousand years ago. The Mittelland, that covers one third of the territory, is a region with hills and fertile land, with loads of lakes, as the Lake of Geneva.
The country has several rivers, amongst them are Rhin and Rhone. The demographic growth of the country (7.5 million inhabitants) is low, partly due to the immigration policy. However, the population is relativly dense, and concentrated in the Mittelland region , where you find the biggest cities: Zürich, Geneva, Lausanne and Berne (the capital).
