It’s about 130km (~80 miles) from Thusis to Tirano and the Canton of Graubünden and the Rhaetian Railway have come up with a pip of a way to see it. Hikers walked it while wearing hi-def video cameras and the jaunts are available for the clicking. No joke, this is an algorithm and a treadmill away from a holodeck. Visit webwandern.ch (or click on the image), select any one of ten starting points and let the friendly ibex take you through some breathtaking scenery. All the virtues of travel without the hellish slog through the modern travel industry. The website is exquisite, in and of itself.
