You can find Grimsel Pass in the barren, mountainous Grimsel Region. The road is famous for its winding paths, scenic vistas of Lake Grimsel, and the historic Grimsel Hotel. From the Grimsel Pass, you will be able to explore the natural wonders of the surrounding area.

Overview: Grimsel Pass

Grimsel Pass is a high mountain pass located in the Swiss Alps. It links the Haslital valley in the Bernese Oberland with the Obergoms region in Upper Valais.

The paved road is 38 kilometers long and stretches from Gletsch to Guttanen. It serves as the only direct mountain road pass connecting Bern and Valais, two of Switzerland’s key mountain tourism areas.

Grimsel Pass is the European watershed. To the south, the water flows to the young Rhône, later to the Mediterranean Sea. To the north, the water flows to the Aare, later into the Rhine River until it reaches the North Sea.

Throughout its history, the Grimsel Region has confronted formidable natural challenges, from avalanches to wildfires. It experiences a harsh climate, with extreme temperature fluctuations and heavy snowfall during the winter months.

However, despite its historical association with farming on arduous and less fertile terrain, this region now holds a central position in Switzerland’s energy landscape, thanks to hydroelectric power generation. Abundant precipitation and the melting ice from the glacier have made this area a valuable source of renewable energy, harnessing the forces of nature for sustainable power generation.

Historical Significance of Grimsel Pass

Grimsel Pass has been an important road since ancient times. In 1397, the Grimsel Route contract established standard rules for the residents and, since then, has been used to regulate the upkeep of the roads, trails, and bridges. Grimsel Pass has always been a major trade route connecting northern and southern Europe, in particular Italy and Vindonissa (now in Canton Aargau). The South’s tradesmen exchanged its food for the North’s goods.1

Grimsel’s Hospice served as a refuge for impoverished travelers. Cheese, wine, bread, and wood were available to the travelers here. In time, the hospice would also attract other guests such as academics, painters, and mountaineers. Additionally, it would also be known as a good place to conduct glacier research.2

Grimsel Pass was constructed with the help of the inhabitants of Guttannen and hundreds of Italian construction workers. Between 1891 and 1894, the workers completed the first road. Furthermore, the Marzoli Tunnel (in honor of the foreman Marzoli) opened in 1985, after the original road was threatened by falling rocks from the mountain.3

Grimsel Pass Road Conditions

Image of Grimsel Pass Road and Guard Rails by

Grimsel Pass is a narrow and winding mountain pass with steep drops and hairpin turns. The roads are well-maintained and marked with signs. Furthermore, there are safety features such as guard rails.

From Valais, the mountain pass begins similarly to Furka Pass. But you have to turn left instead of heading straight for Furka Pass at the fork in the road. The road is well-maintained and offers a smooth driving experience, making it a popular destination for tourists and locals alike.

There are several places on the road where you can stop. In addition, there is a rest stop where you can get some local food and refreshments.

Nonetheless, drivers are advised to exercise caution when driving on the pass. At the top of the mountain pass, we saw several animals crossing the road, so be aware of that too. You can drive here with confidence and have a pleasant driving experience because of the well-maintained roads and infrastructure.

When is the Grimsel Pass Open?

Grimsel Pass is open to traffic from May until the end of October or the beginning of November. During winter months, the mountain pass is closed for safety reasons. Winter can be particularly hazardous due to heavy snowfall and avalanches.

Before beginning a journey, it is recommended that visitors consult the weather forecast, road availability schedule, and road conditions.
