The Swiss Travel Pass provides a significant discount for the journey to Jungfraujoch, but it does not cover the entire trip for free. With the pass, you can travel for free as far as Grindelwald or Wengen. For the final, most expensive leg of the journey—the mountain railway from Grindelwald Terminal or Wengen to the "Top of Europe" at Jungfraujoch—you receive a 25% discount on the ticket price. As of 2026, many travelers find that the "Jungfrau Travel Pass" or the "Berner Oberland Pass" offers better value if they plan to spend several days in that specific region, as these regional passes often include the Eiger Express and other lifts at a higher discount or for free. If you have a Swiss Half Fare Card instead of the full Swiss Travel Pass, you actually get a 50% discount on the entire route, which sometimes results in a lower total cost for that specific excursion. Regardless of your pass, a seat reservation (approx. CHF 10) is highly recommended during the peak summer months.
