Via Albula/Bernina, Stage 4/10
39 tunnels, 55 bridges, a 1123-meter height difference: the Albula section of the Rhaetian Railway is a superb example of how railways have opened up access to the Alpine countryside. On the Preda to Bergün section, there is an railway adventure trail: a 2.5-hour hike with information about the world's most spectacular railway line.
