Yes, the Swiss Travel Pass covers 100% of the train journey to Grindelwald. In 2026, the pass remains incredibly efficient for the Bernese Oberland region. You can travel for free on the "Berner Oberland Bahn" (BOB) from Interlaken Ost directly into the heart of Grindelwald. Once you arrive, the pass also covers local yellow PostBuses within the village. However, there is a distinction for mountain excursions: while the train to the village is free, cable cars and cogwheel trains going above Grindelwald—such as the flight to First or the Eiger Express—typically require a separate ticket, though Swiss Travel Pass holders receive a 50% discount. The only exception is the trip to Jungfraujoch, which usually offers a smaller 25% discount from Grindelwald onwards.
