The Swiss Travel Pass does not make the journey to the "Jungfraujoch - Top of Europe" entirely free, but it does provide a significant 25% discount on the final and most expensive leg of the trip. Specifically, the pass covers the full cost of travel from major cities like Zurich or Lucerne to Interlaken, and then up to the villages of Wengen or Grindelwald. From Wengen or Grindelwald up to the Jungfraujoch summit (via the Eiger Express or the traditional cogwheel train), you must purchase a separate ticket at the 25% discounted rate. In 2026, this discounted round-trip ticket typically costs around 140 to 170 CHF depending on the season. It is a common misconception that the pass covers the whole trip, as it does for Mt. Rigi or Stanserhorn. However, the 25% saving is still substantial, and the pass remains the best value for getting to the base of the mountains. For those looking to save more, the Bernese Oberland Pass or a "Good Morning Ticket" (early bird) can sometimes be combined with the Swiss Pass for better deals on this specific bucket-list excursion.
