Yes, the funicular ride from Interlaken Ost to Harder Kulm is fully included in the Jungfrau Travel Pass. In 2026, the Jungfrau Travel Pass (which is available for durations of 3 to 8 days) offers unlimited travel on the specific network of mountain railways, cable cars, and buses within the Jungfrau region. Harder Kulm, known as the "Top of Interlaken," is one of the key excursions covered by the pass, offering stunning views of the Eiger, Mönch, and Jungfrau peaks as well as Lakes Thun and Brienz. You simply show your digital or printed pass at the funicular station to board. Keep in mind that while the transport is included, any food at the panoramic restaurant or special events at the top will be an extra cost. Also, remember that the Harder Kulm funicular is seasonal, typically operating from mid-April to late November; if you visit in the dead of winter, the funicular will be closed, regardless of whether you have a pass. It remains one of the best "quick trips" to maximize the value of your Jungfrau Travel Pass.
