For fans of the fantasy series, Switzerland’s ultra-efficient train network makes it easy to shadow Bilbo and Frodo Baggins’ footsteps and retrace Tolkien’s journey from the town of Interlaken (seen by Tolkien scholars as inspiration for The Hobbit’s Esgaroth, or Lake-Town) to the moraines beyond the mountain village of Mürren (see Mount Doom in the final part of the Rings’ trilogy).
