The Swiss Travel Pass (and its Flex version) provides an incredible range of mountain access for travelers in 2026. As of the current regulations, the pass offers unlimited, 100% free travel to the summits of Mount Rigi, Stanserhorn, and Stoos. These are unique because they involve cogwheel trains, the world's first open-top "CabriO" cable car, and the world's steepest funicular, respectively. For the majority of other famous Swiss peaks, the pass acts as a 50% discount card. This includes major excursions like Mount Pilatus, Mount Titlis, and Schilthorn. Notably, the journey to the Jungfraujoch (Top of Europe) is a bit different; the Swiss Travel Pass covers the train as far as Wengen or Grindelwald for free, but from there to the summit, you typically receive a 25% discount. Other regional gems like Harder Kulm and Schynige Platte are usually 50% off. Because these inclusions can vary slightly by season, it is always a good idea to check the current "Area of Validity" map provided by SBB before you head up the mountain.
