Gandegg Hut

Trockener Steg is a minor prominence in the area between the Matterhorn and the Breithorn, south of Zermatt in the canton of Valais. It lies at a height of 2,939 meters (9,642 ft) above sea level, near the front of the Upper Theodul Glacier. A cable car station lies on the summit and gives access to the Klein Matterhorn.

The Theodul Glacier (also spelled Theodule Glacier; German: Theodulgletscher, French: Glacier du Théodule, Italian: Ghiacciaio del Teodulo) is a glacier of the Alps, located south of Zermatt in the canton of Valais. It lies on the Swiss side of the Pennine Alps, although its upper basin touches the Italian region of the Aosta Valley. The glacier descends from the west side of the Breithorn (4,164 metres (13,661 ft)) and splits into two diverging branches above Gandegg: the Upper Theodul Glacier (Oberer Theodulgletscher), spilling on a high plateau near Trockener Steg, together with the Furgg Glacier, and the Lower Theodul Glacier (Unterer Theodulgletscher), reaching a height of about 2,500 metres (8,202 ft) above the Gorner Glacier. Both branches are part of the Rhone basin, through the rivers Gornera, Mattervispa, and Vispa. Slightly above the glacier splitting is the Theodul Pass, crossing the border between Switzerland and Italy, and connecting Zermatt to Breuil-Cervinia. On the west, the Theodul Glacier is overlooked by the Matterhorn. Until about 1980s the Lower Theodul Glacier was still connected to the Gorner Glacier and one of its tributaries. The upper section of the Theodul Glacier consists of a flat plateau at around 3,800 metres, named Breithorn Plateau. The plateau lies between the Breithorn, the Gobba di Rollin and the Klein Matterhorn. The Breithorn Pass (3,814 m) separates the Breithorn from the Gobba di Rollin (French: Bosse de Rollin). A 3,795 m high saddle lies between the Gobba di Rollin and the Klein Matterhorn. Between the Klein Matterhorn and the Breithorn is a distinct glacier, named Klein Matterhorn Gletscher, which joins the Lower Theodul Glacier at about 3,000 metres. The Breithorn Plateau area can be easily accessed by several cable cars connecting Zermatt to the Klein Matterhorn. At around 3,500 metres is the Plateau Rosa, whose name derives from the Valdôtain patois term Rouése, meaning "ice" (as for the nearby Monte Rosa). This area lies between Testa Grigia (French: Tête grise) (3,479 m) and the Klein Matterhorn, south of and slightly above the Theodul Pass. Southeast of Testa Grigia is a saddle named Passo di Ventina Nord (3,445 m). This area can also be easily accessed by several cable cars connecting Breuil-Cervinia to Testa Grigia. Most of the glacier is part of the year-round ski area marketed as Matterhorn Glacier Paradise. It is the highest in Europe and largest summer ski area in the world, with 21 kilometres of prepared pistes. The culminating point is on the summit of Gobba di Rollin and the lowest is above Trockener Steg. The Matterhorn Glacier Paradise links the ski areas of Zermatt and Breuil-Cervina. Ski lifts connect Trockener Steg, Theodul Pass, Testa Grigia, Klein Matterhorn and Gobba di Rollin. A chair lift also connects Trockener Steg to the Furggsattel (3,349 m), north of the Theodul Pass. Several lakes recently formed at the bottom of the Upper Theodul Glacier, west of Trockener Steg. The largest, named Theodulgletschersee is 7.76 ha wide and lies at an elevation of 2,851 metres above sea level. It is the highest lake over 4 ha in Switzerland and the largest lake in the Matter Valley (the valley of Zermatt). The second-largest, named Furggsee is 2.57 ha wide and lies at 2,874 metres.

The Theodulhorn (French: Mont de Saint-Théodule - 3,469 m) is a mountain of the Pennine Alps, overlooking the Theodul Pass on the border between Switzerland and Italy. It lies south of Zermatt (in Valais) and east of Breuil-Cervinia (in the Aosta Valley). The northern side of the mountain is heavily glaciated and is part of a ski area. The Theodulhorn is the easternmost summit of the range descending from the south-east ridge of Matterhorn, named Furgggrat. It is named for Theodul Pass, which is in turn named for Saint Theodul, patron saint of the Valais.

The Klein Matterhorn (sometimes translated as Little Matterhorn) is a peak of the Pennine Alps, overlooking Zermatt in the Swiss canton of Valais. At 3,883 metres (12,740 ft) above sea level, it is the highest place in Europe that can be reached by aerial tramway or gondola lift, as well as by any other means of transport. The Klein Matterhorn is part of the Breithorn massif and overlooks on its south side the almost equally high flat glacier named Breithorn Plateau, just north of the international border with Italy. The name "Klein Matterhorn" is a reference to its much larger neighbour, the Matterhorn, which lies 7 km (4.3 mi) away across the Theodul Pass. The Klein Matterhorn, with the adjacent ski-lifts to the slightly higher Gobba di Rollin, is also a year-round ski area, marketed as "Matterhorn Glacier Paradise", and part of the international ski area between Zermatt and Breuil-Cervinia. Fast ascents to a height above 3,000 metres (9,800 ft) will frequently lead to headaches or other symptoms of altitude sickness with sensitive people.

Refuge du Théodule is a refuge in the Pennine Alps located at the Theodulpass between the Mattertal and Valtournanche in the Aosta Valley, Italy.

Theodul Pass, elevation 3,295 metres (10,810 ft), (German: Theodulpass, Italian: Colle del Teodulo, French: Col de Saint-Théodule, Walser German: Theoduljoch) is a high mountain pass across the eastern Pennine Alps, connecting Zermatt in the Swiss canton of Valais and Breuil-Cervinia in the Italian region of Aosta Valley. Theodul Pass is the lowest and the easiest pass between the valleys of Zermatt and Valtournanche. The pass lies between the Matterhorn on the west and the Breithorn on the east and is overlooked by the Theodulhorn and Testa Grigia. The Rifugio del Teodulo (hut) is located just above the pass. The east side of the pass is covered by large glaciers part of the Theodul Glacier system and is part of a year-round ski area. On the Italian side, the pass can be reached from Breuil-Cervinia by a dead-end trail. On the Swiss side, trails go up from Trockener Steg and Gandegg Hut.

The Furgghorn (German, Italian: Cima del Breuil) is a mountain of the Pennine Alps, located on the boundary between the canton of Valais (Switzerland) and Aosta Valley (northern Italy). It lies on the range south-east of the Matterhorn, near the Theodul Pass. The closest locality is Breuil-Cervinia on the Italian side. The closest locality on the Swiss side is Zermatt.

The Sunnegga Paradise is a ski area that forms part of the Zermatt ski resort, in Valais, Switzerland. The area relating to skiing is found on the Rothorn mountain, above the town of Zermatt. The trails extend to the valley floor between the Rothorn and Gornergrat mountains, and includes the ski runs directly down to the Oberhausern area of the town of Zermatt, terminating at the passenger lift that takes skier directly down inside the funicular train station in the area. The Sunnegga area catches a large amount of sun due to its unique topography, often despite the rest of Zermatt being submerged in cloud.

The Breithorn (German for literally "broad horn"; 13,661 ft. or 4,164 m) is a mountain range of the Pennine Alps with its highest peak of the same name (but also called Breithorn (Western Summit)), located on the border between Switzerland and Italy. It lies on the main chain of the Alps, approximately halfway between the Matterhorn and Monte Rosa and east of the Theodul Pass. Most of the massif is glaciated and includes several subsidiary peaks, all located east of the main summit: the Central Breithorn, the western Breithorn Twin (or Eastern Breithorn), the Gendarm (or eastern Breithorn Twin) and the Roccia Nera. The main summit is sometimes distinguished by the name Western Breithorn (German: Breithorn (Westgipfel), Italian: Breithorn Occidentale). The nearest settlements are Zermatt (Valais) and St-Jacques (Aosta Valley). The Breithorn is considered the most easily climbed 4,000 m Alpine peak. This is due to the Klein Matterhorn cable car which takes climbers to over 3,820 m (12,700 ft) from Zermatt for a starting point. The standard route (SSW flank) is from the Italian side of the mountain (the south side) and continues over a glacial plateau before climbing to the summit on a 35 degree snow slope. However, inexperienced mountaineers may run into severe difficulty if caution is not taken near cornices or in bad weather. For experienced climbers wanting more of a challenge, the half traverse of the Breithorn crest is another option. The Breithorn was first climbed in 1813 by Henry Maynard (climber), Joseph-Marie Couttet, Jean Gras, Jean-Baptiste Erin and Jean-Jacques Erin.

The Schwarzsee (German for "Black Lake") is a small lake near Zermatt in the canton of Valais, Switzerland. It is located below the Matterhorn next to the mountain ridge (2,583 m (8,474 ft)) and to the cable car station of the same name at an elevation of 2,552 m (8,373 ft). Its surface area is 0.5 ha. A chapel dedicated to Mary of the Snows – the chapel Maria zum Schnee – lies on the edge of the lake. It can be reached by cable car from Zermatt.

Refuge Guides du Cervin is a refuge in the Alps in Aosta Valley, Italy.

Testa Grigia (French : Tête grise, lit. "grey head") (3,479 m) is a rocky prominence above the Theodul Pass, located on the border between Italy (Aosta Valley) and Switzerland (Valais). It overlooks the Plateau Rosa section of the Theodul Glacier on its east side.
