In 2026, the Brienz Rothorn Bahn (the historic steam cogwheel railway) is not fully included in the Swiss Travel Pass, but it is heavily discounted. Holders of the Swiss Travel Pass receive a 50% discount on the ticket price for the journey from Brienz to the summit of the Brienzer Rothorn. While the pass covers most "regular" trains, buses, and boats for free, the Brienz Rothorn Bahn is considered a "special mountain excursion." To get the discount, you must present your valid Swiss Travel Pass at the ticket counter in Brienz or select the "Half Fare/Swiss Travel Pass" option when booking online. A 2026 "pro-tip" for travelers: if you hold a Berner Oberland Pass or a Tell-Pass, the journey is actually 100% free. Since the train is a popular steam-powered vintage experience with limited capacity, it is highly recommended to pay the small additional fee (approx. 8 CHF) for a seat guarantee in advance, especially during the peak summer months of July and August, as the vintage carriages can fill up quickly with tourists seeking that iconic panoramic view over Lake Brienz.
