The Swiss Travel Pass does not cover the entire journey to Jungfraujoch for free, but it provides a significant discount. In 2026, the pass allows for free travel as far as Wengen or Grindelwald. From these points up to the "Top of Europe" station, you must purchase a separate mountain excursion ticket, for which the Swiss Travel Pass grants you a 25% discount. This is a departure from most other trains and boats in Switzerland, which are 100% free with the pass. However, the newly opened Eiger Express tricable gondola from Grindelwald Terminal is also included in this 25% discount structure, providing a much faster way to reach the Eigergletscher station before the final tunnel ascent. Because the Jungfraujoch ticket is one of the most expensive in the world (often over $200 round-trip), even a 25% discount is a substantial saving. It is a "pro-tip" to check the live weather webcams at the Jungfraujoch station before buying your ticket, as the high price is only worth it if the skies are clear for the glacier views.
