The Alpine region of Switzerland, conventionally referred to as the Swiss Alps, represents a major natural feature of the country and is, along with the Swiss Plateau and the Swiss portion of the Jura Mountains, one of its three main physiographic regions. The Swiss Alps extend over both the Western Alps and the Eastern Alps, encompassing an area sometimes called Central Alps. While the northern ranges from the Bernese Alps to the Appenzell Alps are entirely in Switzerland, the southern ranges from the Mont Blanc massif to the Bernina massif are shared with other countries such as France, Italy, Austria and Liechtenstein.
The Grisons or Graubünden, more formally the Canton of the Grisons or the Canton of Graubünden, is one of the twenty-six cantons of Switzerland. It has eleven regions, and its capital is Chur. The German name of the canton, Graubünden, translates as the "Grey Leagues", referring to the canton's origin in three local alliances, the Three Leagues. The other native names also refer to the Grey League: Grischùn in Sutsilvan, Grischun in the other forms of Romansh, and Grigioni in Italian. "Rhaetia" is the Latin name for the area. The Alpine ibex is the canton's heraldic symbol.
Valais, or Wallis, more formally the Canton of Valais, is one of the 26 cantons forming the Swiss Confederation. It is composed of thirteen districts and its capital and largest city is Sion. The flag of the canton is made of thirteen stars representing the districts, on a white-red background.
The Rhaetian Railway, abbreviated RhB, is a Swiss transport company that owns the largest network of all private railway operators in Switzerland. Headquartered in Chur, the RhB operates all the railway lines of the Swiss canton of Grisons, except for the line from Sargans to the cantonal capital, Chur, which are operated by Swiss Federal Railways (SBB CFF FFS), as well as the line from Disentis/Mustér to the Oberalp Pass and further on to Andermatt, Uri, which is operated by Matterhorn Gotthard Bahn (MGB). Inaugurated in 1888 and expanded from 1896 onwards in various sections, the RhB network is located almost entirely within Grisons, with one station across the Italian border at Tirano.
Reichenau is a village in the municipality of Tamins in the Canton of Graubünden, Switzerland, where the two Rhine tributaries Vorderrhein and Hinterrhein meet, forming the Alpine Rhine. It is a major traffic junction of the routes from Chur towards the Oberalp Pass and Lukmanier Pass and from Chur towards San Bernardino Pass and Julier Pass.
The Gotthard Road Tunnel in Switzerland runs from Göschenen in the canton of Uri at its northern portal, to Airolo in Ticino to the south, and is 16.9 kilometres (10.5 mi) in length below the St Gotthard Pass, a major pass of the Alps. At time of construction, in 1980, it was the longest road tunnel in the world; it is currently the fifth-longest. Although it is a motorway tunnel, part of the A2 from Basel to Chiasso, it consists of only one bidirectional tube with two lanes. With a maximum elevation of 1,175 metres (3,855 ft) at the tunnel's highest point, the A2 motorway has the lowest maximum elevation of any direct north-south road through the Alps.
The Albula Pass is a Swiss mountain pass in the canton of Graubünden. It lies at the heart of the Albula Alps, on the watershed between the Albula, tributary of the Rhine and the Ova d'Alvra, tributary of the Inn. Overlooking the pass are the ranges of Piz Üertsch (north) and Crasta Mora (south).
The Flüela Pass is a high mountain pass of the Swiss Alps in Graubünden. Traditionally considered the boundary between the Albula and Silvretta Alps, the pass crosses the watershed / drainage divide between the basins of the Rivers Rhine and Danube. The pass is overlooked by the Flüela Schwarzhorn and the Flüela Wisshorn. The summit of the pass lies between the lakes Lai da la Scotta and Lai Nair.

San Bernardino Pass is a high mountain pass in the Swiss Alps connecting the Hinterrhein and the Mesolcina (Misox) valleys between Thusis and Bellinzona. Located in the far eastern side of the Western Alps it is not to be confused with the Great St Bernard Pass and the Little St Bernard Pass. The top of the pass represents both the Italo-German language frontier and the watershed between the Po basin and the Rhine basin. Marscholsee is within the pass at an elevation of 2,053 m (6,736 ft).
The Vorderrhein is one of the two sources of the Rhine. Its catchment area of 1,512 square kilometres is located predominantly in the canton of Graubünden (Switzerland). The Vorderrhein is about 76 kilometres (47 mi) long, thus more than 5% longer than the Hinterrhein/Rein Posteriur. The Vorderrhein, however, has an average water flow of 53.8 m3/s (1,900 cu ft/s), which is less than the flow of the Hinterrhein. According to the Atlas of Switzerland of the Swiss Federal Office of Topography, the source of the Vorderrhein—and thus of the Rhine—is located north of the Rein da Tuma and Lake Toma.
