Piz Üertsch

Piz Blaisun (3,200 m) is a mountain of the Albula Alps, located north of the Albula Pass in the canton of Graubünden. Its summit is the tripoint between the Val Tuors, the Val d'Alvra (Albula valley) and the Val d'Es-cha.

The Albula Tunnel is the centrepiece of the Albula Railway, which forms part of the Rhaetian Railway network, in the Canton of Graubünden, Switzerland. With its maximum elevation of 1,820 m (5,970 ft) above sea level, it is amongst the highest tunnels in the Alps, and has a mountain overlay of up to 950 m (3,120 ft). The tunnel has a length of 5,865 m (19,242 ft). It opened for traffic in 1903.The northern portal of the tunnel is at Preda, in Bergün, and the southern portal at Spinas, in the Bever valley. At a total length of 5,865 m (19,242 ft), the tunnel connects the Albula Valley with the Engadin Valley, and, in so doing, passes under the watershed between the Rhine and the Danube a few kilometres west of the Albula Pass. The tunnel serves both passenger and freight traffic. The Glacier Express passes through it daily. During the winter season, car transporter trains operating between Thusis and Samedan also used the tunnel until 2011. Due to the threat of rockfalls and general deterioration over time, it was planned for the original tunnel to have been renovated during the 2020s. But in 2010, the Rhaetian Railway announced that it had identified the construction of a second tunnel alongside the first as its preferred option, with one of several reasons being a relatively minor difference in cost. Costed at around CHF 244 million, construction commenced during 2014. In comparison to the original Albula Tunnel, the new bore is considerably larger due to newer operational and safety standards. The second tunnel is set to be opened to traffic in 2024, with completion of the project including refurbishment of the original tunnel by 2025. Once completed, around 15,000 trains are predicted to use the tunnel each year; it has been built to allow for a maximum speed of 120 km/h.

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 main road passes crossing the Albula Alps (from central Graubünden to Engadin) are the Julier Pass and the Albula Pass. On the margin are also the Flüela Pass and the Septimer Pass (bridle path only). The Albula Pass, in the middle of the range, is also an important axis of the Rhaetian Railway, connecting Chur to St. Moritz through the Albula Tunnel. Both pass road and railway traverse the locality of Bergün on the river Albula, the most central town within the Albula Alps.

Spinas railway station is a railway station at the south portal of the Albula Tunnel in the municipality of Bever, in the Swiss canton of Graubünden. It is located on the 1,000 mm (3 ft 3+3⁄8 in) metre gauge Albula line of the Rhaetian Railway. Services operate every two hours to this station.

The Crasta Mora is a mountain of the Albula Alps, overlooking Bever in the canton of Graubünden. It lies at the eastern end of the range between the Albula Pass and the Val Bever.

Piz Kesch (German) or Piz d'Es-cha (Rumantsch) is a peak in the Albula Alps of the Rhaetian Alps in Switzerland. At 3,418 metres (11,214 ft), it is the highest peak in the Albula Alps and the municipality of Bergün, Grisons. The first ascent was made 1846 by J. Coaz, J. Rascher, C. Casper and J. Tscharner.

The Albula Pass (Romansh: Pass d'Alvra or , German: Albulapass) (el. 2312 m) 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 Albula Pass is an important axis from central Graubünden to Engadin. It is traversed by a paved road from Thusis to La Punt, via Bergün. It is also traversed by the Albula Railway, although at a lower elevation through the Albula Tunnel (1,820 m), from Thusis to Bever, also via Bergün. On the summit of the pass is a hospice. East of the pass, on the Engadin side, is a lake named Albulasee (2,294 m) which is 4.2 ha large. West of the pass, at a further distance, is the larger Lai da Palpuogna, a popular stop on the Albula road. The Albula Pass is one of the three paved road passes connecting the Engadin with the northern Grisons, the two other being the Julier Pass and the Flüela Pass. Albula Pass

Lai da Palpuogna (Romansh; German: Palpuognasee) is a mountain lake at Albula Pass in the municipality of Bergün, in the Grisons, Switzerland. Surrounded by pine forests and majestic peaks, the lake offers a serene setting that captivates visitors throughout the year. The crystal-clear waters reflect the sky and mountains, creating a picturesque scene that's perfect for photography. In a 2007 television program of the Swiss channel SF 1, the lake was voted the most beautiful place in Switzerland. Many tourists and locals visit this natural wonder to hike, picnic, and immerse themselves in its tranquil beauty.

The Porchabella Glacier (Romansh: Vadret da Porchabella) is a 2.5 km long glacier (2005) in the Albula Range in the canton of Graubünden in Switzerland. In 1973 it had an area of 2.58 km2. The glacier lies at the foot of Piz Kesch and Piz Val Müra. It gives birth to the river Ava da Salect which ends in the Albula.

Preda railway station is a railway station in the municipality of Bergün Filisur, in the Swiss canton of Graubünden. It is located on the 1,000 mm (3 ft 3+3⁄8 in) metre gauge Albula line of the Rhaetian Railway. Hourly services operate on this section of the line.

Preda is a small village within the Swiss municipality of Bergün Filisur (until the end of 2017 Bergün/Bravuogn), district of Albula, Canton Graubünden (Grisons), in the East of Switzerland.The name Preda, like Prada, derives from the Latin pratum = meadow.Preda is located in the upper valley of the Albula Alps. It lies on the road over the Albula Pass at 1789 metres above sea level (a.s.l.) and at the north portal of the Albula Tunnel of the Rhaetian Railway. To reach Preda, while avoiding too steep ramps, the Rhaetian Railway needs passing several valleys over impressive viaducts and cross-cutting the mountain in several spiralling tunnels (Kehrtunnel in German). This allows the railway to overcome a difference in altitude of 416 metres from Bergün to Preda. The line runs from Chur or Davos to St. Moritz and ends at the route of the Glacier Express.

Piz Ot (Romansh: "high peak") is a mountain of the Albula Alps, located west of Samedan in the canton of Graubünden. Reaching a height of 3,246 metres above sea level, it is the culminating point of the range lying north of the Pass Suvretta. The normal route to the summit starts from the heights of St. Moritz and Samedan, on the southern side of the mountain.
