Langwieser Viaduct

The Langwieser Viaduct is a striking stone arch bridge that carries the Rhaetian Railway (RhB) over the Plessur River near the village of Langwies, just outside Arosa. Completed in 1914, this 284-meter-long viaduct is one of the most impressive engineering feats on the line, soaring 62 meters above the valley floor. Visitors can view the viaduct from below on a walking path or ride the train across it for a thrilling perspective. The structure's graceful arches blend harmoniously with the surrounding alpine landscape, making it a favorite subject for photographers. In winter, the viaduct is often dusted with snow, creating a fairy-tale scene. The best views are from the hiking trail that descends from Langwies station or from the road bridge nearby.
