Bernina Range in the context of "Muretto Pass"

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 Swiss Alps comprise almost all the highest mountains of the Alps, such as Dufourspitze (4,634 m [15,203 ft]), the Dom (4,545 m [14,911 ft]), the Liskamm (4,527 m [14,852 ft]), the Weisshorn (4,506 m [14,783 ft]) and the Matterhorn (4,478 m [14,692 ft]). The other following major summits can be found in this list of mountains of Switzerland.

The Grison Alps are the mountains of the Graubünden canton of Switzerland (Grisons being the English name for the Graubünden region). There are many significant peaks in the Grison Alps, including the Tödi (3,614 m) and the highest peak, Piz Bernina (4,049 m). Many of the mountain ranges feature extensive glaciers, such as at the Adula, the Albula, the Silvretta, the Bernnina or the Rätikon range. The Grison Alps include parts of both the Eastern Alps and the Western Alps. The Eastern Alps located in Graubünden are the Rhaetian Alps, which is part to the Central Eastern Alps.

The Rhaetian Alps consists of the following mountain ranges: Samnaun Alps, Rätikon, Silvretta, Sesvenna Range, Albula Range, Plessur Range, Oberhalbstein Range, Livigno Range, Bregaglia Range and the Bernina Range. The Western Alps located in Graubünden, include portions of the Lepontine Alps and the Glarus Alps.

Piz Bernina (Romansh, Italian: Pizzo Bernina, Italian pronunciation: [ˈpittso berˈniːna]) is the highest mountain in the Eastern Alps, the highest point of the Bernina Range, and the highest peak in the Rhaetian Alps. It rises 4,048 m (13,281 ft) and is located south of Pontresina in the Bernina Region and near the major Alpine resort of St. Moritz, in the Engadin valley. It is also the most easterly mountain higher than 4,000 m (13,000 ft) in the Alps, the highest point of the Swiss canton of Grisons, and the fifth-most prominent peak in the Alps. Although the summit lies within Switzerland, the massif is on the border with Italy. The "shoulder" (4,020 m (13,190 ft)) known as La Spedla is the highest point in the Italian Lombardy region.

Piz Bernina is entirely surrounded by glaciers, of which the largest is the Morteratsch Glacier.

Piz Palü is a mountain in the Bernina Range of the Alps, located between Switzerland and Italy. It is a large glaciated massif composed of three main summits, on a ridge running from west to east. The main (and central) summit is 3,899 metres high and is located within the Swiss canton of Graubünden, although the border with the Italian region of Lombardy runs about 100 metres west of it at almost the same height (3,898 m). The western summit (3,823 m; on the international border) is named Piz Spinas and is the only one not covered by ice. The eastern summit (3,882 m; within Switzerland) is named Piz Palü Orientale. The name Palü derives from the Latin palus, meaning a swamp, and the mountain is said to be named after the Alpe Palü, a high alpine pasture some 4 km to its east.

The Albula Alps are a mountain range in the Alps of eastern Switzerland. They are considered to be part of the Central Eastern Alps, more specifically the Western Rhaetian Alps. They are named after the river Albula. According to AVE (see map), the Albula Alps are separated from the Oberhalbstein Alps in the west by the Septimer Pass and the valley of the Sursés; from the Plessur Alps in the north-west by the Landwasser valley; from the Silvretta group in the north-east by the Flüela Pass; from the Sesvenna Alps in the east by the Inn valley (Engadine); from the Livigno Alps in the south-east by the Inn valley; from the Bernina Range in the south by the Maloja Pass and the Inn valley.

The chief summit of the Albula Alps is Piz Kesch, which is also the highest summit of the Eastern Alps north of the Inn. Other mountains with both a high elevation and a high prominence are Piz Calderas, Piz Ela, Piz Ot and Piz Vadret. The Albula Alps are drained by the rivers Albula, Gelgia, Landwasser and Inn and Mera. Near the Lunghin Pass is the tripoint between the Gelgia, Inn and Mera. This is the tripoint between the basins of the North Sea, Black Sea and Mediterranean Sea.

The Livigno Alps are a mountain range in the Alps of eastern Switzerland and northern Italy, around the Italian village Livigno. They are considered to be part of the Central Eastern Alps.

The Livigno Alps are separated from the Bernina Range in the south-west by the Bernina Pass; from the Albula Alps in the north-west by the Upper Engadin valley; from the Sesvenna Alps in the north-east by the Spöl valley; from the Ortler Alps in the east by the Passo di Fraéle and the upper Adda River valley (Valtellina).

The Bernina Pass (el. 2,328 m or 7,638 ft.) (Italian: Passo del Bernina) is a high mountain pass in the Bernina Range of the Alps, in the canton of Graubünden (Grisons) in eastern Switzerland. It connects the famous resort town of St. Moritz in the Engadin valley with the Italian-speaking Val Poschiavo, which ends in the Italian town of Tirano in Valtellina. The pass lies a few kilometres east of Piz Bernina, and south of Val Minor.

The Bernina Pass is crossed by both the Hauptstrasse 29 road and the Bernina railway line, with a popular tourist train, the Bernina Express operating year-round between Chur and Tirano. The train crosses the pass west of the road at a slightly lower 2,253 metres (7,392 ft) (at Ospizio Bernina) – it is the highest adhesion railway route in Europe.
