Fuorn Pass, Mountain pass in Graubünden, Switzerland

Fuorn Pass is a mountain pass at 2149 m in Graubünden, separating the Sesvenna Group from the Ortler Alps and linking Zernez in the Engadine with Val Müstair. The H28 road climbs 19.1 km from Zernez through the Swiss National Park, its only road, to the pass summit just outside the park. Grey asphalt curves between pale rock and low shrubs, with limestone slopes and conifers above.

The road through the pass opened in 1871, creating an important connection for people and goods between communities on either side of the mountains. This route made travel between the two valleys much more direct than before.

The name comes from ancient iron foundries that once operated in the area, and you can still find traces of these structures along nearby trails.

The road stays open during summer months and has gentle grades, making it accessible for both cars and cyclists crossing the mountains. The area around the pass is easy to navigate and explore at a comfortable pace.

In 2004, near the pass, the largest honey fungus clone in Europe was found: a fungus about 1,000 years old with an estimated diameter of 500 to 800 metres. In July 2005 a brown bear, JJ2, was photographed at the pass; bears had been extinct in Switzerland since 1904.
