The Swiss Travel Pass covers the Golden Pass train ride because all train, bus and boat rides within Switzerland are included in the pass.
The GoldenPass line is one of Switzerland’s top panoramic train rides taking you through diverse alpine scenery. The journey can be taken in parts, or in one go all the way from Montreux to Lucerne, via Interlaken, or vice versa.
It can also be combined with a longer itinerary in Switzerland where you will most certainly always travel between Lucerne and Interlaken in order to see some of the highlights of Switzerland.
All three legs of the Golden Pass line are included in the Swiss Travel Pass or Swiss Travel Pass Flex. This is because this travel pass includes all train travel in Switzerland except for a few select mountain railways like the Jungfraujoch.
