Yes, the Swiss Travel Pass provides comprehensive coverage for Interlaken and the surrounding Berner Oberland region in 2026. This includes unlimited travel on the national trains (SBB) arriving at both Interlaken Ost and West stations, as well as the local buses within the town. Furthermore, the pass fully covers the scenic boat cruises on Lake Thun and Lake Brienz, which depart directly from the Interlaken stations. When moving higher into the mountains, the pass covers the trains up to Grindelwald and Wengen at 100%. However, it is important to note that for excursions further up—such as the final leg to the Jungfraujoch (Top of Europe)—the Swiss Travel Pass typically only provides a 25% discount rather than full coverage. For the Schilthorn cable car, as of 2026, the pass usually offers a 50% discount. In short, while Interlaken itself is a "free" zone for pass holders, the ultra-high-altitude "bucket list" attractions nearby will require a discounted supplemental ticket, making the pass an essential tool for navigating this alpine hub.
