Yes, the Swiss Travel Pass fully covers the journey from Zurich to Interlaken in 2026. This includes the direct InterCity (IC) trains via Bern or the more scenic route involving the Luzern–Interlaken Express (part of the GoldenPass Line). With the pass, you do not need to purchase a separate ticket; you simply board the train and show your digital QR code to the conductor when they pass through the cabin. While seat reservations are available for a small fee, they are generally not required on this route unless you are traveling during peak holiday periods or in a large group. The pass also covers any local buses or trams you might need to take within Zurich or Interlaken to reach your hotel. This makes the Swiss Travel Pass an exceptionally high-value option for this route, as it allows you the flexibility to hop on any train at any time without worrying about fluctuating ticket prices or sold-out departures.
