Lucerne to Interlaken to Zermatt- Train choices

Hi Janez, and welcome to the forum! I'm glad you like it.

Most of your trips will indeed be for free with your Swiss Pass. You do need additional seat reservations for the panoramic trains you have in mind: the Golden Pass and the Bernina Express. The trip to the Jungfraujoch will be discounted by 25% from Wengen or Grindelwald on. The downloadable network validity map at the Swiss Pass page shows all details.

As for the Bernina Express: that doesn't run between Zermatt and Lugano indeed. The Bernina Express route is between Chur and Tirano (by train) and Tirano and Lugano (by bus). The quickest route from Zermatt to Lugano is via Göschenen and Bellinzona, and takes between 5 and 6 hours. You could also choose to travel from Interlaken not to Zermatt, but to Chur or St. Moritz, and to get on the Bernina Express there the next day. This issue is irrelevant though if you decide to end your trip in Zermatt. If you choose to do so, you should definitely use the Lötschberg Regio Express (enter 'Goppenstein' as a via-station in the timetable) instead of the quick tunnel connection to Visp. Specifics on all routes, including your outbound trip to Rome, can be found using the timetable.

By the way, our hotel pages on Zurich Airpoirt, Zurich, Lucerne, Interlaken, Zermatt and Lugano may come in handy for you.

Hi Janez. You can plan your trip to Rome by filling out Zermatt as your departure and Rome as your destination station in the timetable. Yes, the Bernina Express is beautiful, but it doesn't really seem to fit into your plans - that is, not if you want to end your trip in Zermatt. The alternative route from Zermatt to Lugano through Göschenen is great too, especially the first part which actually runs the same route as the famous Glacier Express.
