The SwissPass (specifically when loaded with a Swiss Travel Pass) provides comprehensive coverage in the Interlaken region, acting as an "all-access" key to the Bernese Oberland's transport network. It covers all standard trains, buses, and boats within the Interlaken area, including the scenic cruises on Lake Thun and Lake Brienz. For mountain excursions, the pass offers free travel to villages like Mürren and Wengen, and covers the full journey to the Schynige Platte. However, for higher-altitude "private" railways like the journey to the Jungfraujoch (Top of Europe) or the Schilthorn, the SwissPass does not provide free travel but instead offers a 25% to 50% discount on the ticket price. In 2026, the pass also includes free entry to several local museums and serves as your ticket for the Interlaken local bus network. It is an essential tool for travelers who want the flexibility to hop on a boat for a sunset cruise or take a train to a trailhead without worrying about individual ticket costs, making it the most cost-effective way to explore one of Switzerland's most beautiful alpine hubs.
