Yes, the Swiss Travel Pass covers Lake Brienz entirely, granting you unlimited complimentary travel on the scheduled boat services. In 2026, this pass allows you to hop on and off the iconic BLS Lake Cruises that connect Interlaken Ost to the picturesque villages along the shore, such as Iseltwald and Brienz. The journey across the turquoise, glacier-fed waters of Lake Brienz is considered one of the most beautiful boat rides in Switzerland, and with a Swiss Travel Pass, you do not need to purchase a separate ticket; you simply show your digital or physical pass to the conductor upon boarding. The pass also covers the entry-level fare for the boats, though you may choose to pay a small supplement if you wish to upgrade to the first-class deck for a more elevated view and quieter atmosphere. Additionally, the pass provides a 50% discount on the Brienz Rothorn Railway (the famous steam cog train) which departs from right next to the boat landing in Brienz. For a 2026 traveler, the "boat-to-train" connection facilitated by the Swiss Travel Pass remains the most efficient and scenic way to explore the heart of the Bernese Oberland.
