The Swiss Travel Pass can be used to reach the Jungfraujoch, but it does not cover the entire journey for free. In 2026, the Swiss Travel Pass provides free travel on all trains and buses up to the mountain villages of Grindelwald or Wengen. From these points onward—specifically the final leg of the journey via the Eiger Express or the traditional cogwheel train from Kleine Scheidegg to the "Top of Europe"—the pass acts as a discount card. Holders of a Swiss Travel Pass receive a 25% discount on the final ticket price for the Jungfraujoch excursion. While the trip remains one of the most expensive in Switzerland (often costing over $150 even with the discount), the pass still provides significant savings compared to a full-price ticket. It is also important to note that seat reservations are highly recommended for the Jungfraujoch leg in 2026 due to its immense popularity, and these reservations must be paid for separately from the pass discount. For those spending multiple days in the area, a "Jungfrau Travel Pass" might be a more cost-effective alternative to use alongside your Swiss Travel Pass.
