Bernina Pass, Mountain pass in Grisons, Switzerland.
The Bernina Pass is a mountain crossing in the Alps linking the Engadin valley to Val Poschiavo through steep terrain at 2,328 meters elevation. A historic rack railway follows the same route, navigating through 55 tunnels and across 196 bridges carved into the mountainside.
The pass became important in the 15th century when trading agreements between northern and southern communities established regular passage through this route. The railway line was constructed later in the 20th century, transforming how people and goods could cross this difficult mountain barrier.
The railway serves as a living connection between the German-speaking north and Italian-speaking south, allowing people to cross between distinct regions. Travelers notice how this route traditionally linked communities that would otherwise remain isolated from each other.
The road remains open year-round and connects the two valleys directly without detours, making it a straightforward crossing route. Conditions can become challenging during heavy snow, so drivers should be prepared for potential delays and exercise caution.
Three high-altitude lakes sit directly on the pass, creating natural boundaries between the valleys at over 2,300 meters elevation. These lakes are popular photo stops for visitors and reveal how the landscape transforms at this extreme height.
