Yes, Switzerland is fully included in both the Interrail Global Pass and the Interrail Switzerland One Country Pass. The pass is valid on the extensive national network operated by SBB (Swiss Federal Railways), as well as dozens of private railway companies like BLS and RhB. This includes famous scenic routes like the Bernina Express and the Glacier Express, although these specific high-end trains usually require a paid seat reservation even if the "ticket" cost is covered by your pass. Interestingly, the Interrail pass also provides a 25% to 50% discount on many mountain excursions that aren't fully covered, such as the cogwheel train to Jungfraujoch or the Titlis Rotair cable car. For 2026, the pass remains an excellent value for Switzerland, as standard point-to-point tickets in the country are among the most expensive in Europe. Travelers should note that while most local S-Bahn trains and regional expresses require no reservations, the fast international trains (like the TGV Lyria to Paris or EuroCity to Milan) do require them. The pass essentially turns Switzerland into a giant, high-speed playground for rail enthusiasts.
