Ever since I crossed the Landwasser Viaduct on the Glacier Express, I’ve wanted to see this beautiful structure again, and this time, for longer than a minute. I’ve come across photos of it from above and thought that maybe they were taken by drones. But it turns out there is an easy and scenic hike that takes you to a perfect viewpoint to observe the viaduct and watch the trains travel across. When you think about it, it’s pretty amazing that the Swiss built this 136m-high limestone bridge, connecting two mountain tunnels, over a hundred years ago. Today it’s a UNESCO World Heritage sight, and well worth a stop if you’re in Graubündern area. So here are my tips for enjoying this sight.
