Mount Titlis is not fully covered by the Swiss Travel Pass, but it does receive a significant 50% discount. While the Swiss Travel Pass provides free unlimited travel on most trains, buses, and boats throughout Switzerland, high-altitude mountain excursions usually require a separate ticket. With your pass, the train journey from Lucerne to Engelberg is 100% free. Once you arrive in Engelberg, you will need to present your Swiss Travel Pass at the Titlis cable car station to purchase your mountain ascent ticket at half price. This ticket includes the famous "Titlis Rotair" (the world’s first revolving cable car), the Glacier Cave, the Titlis Cliff Walk (Europe's highest suspension bridge), and the Ice Flyer chairlift. For 2026, a few mountains are fully covered (100% free) with the pass, most notably Mount Rigi, Mount Stanserhorn, and Mount Stoos. However, for major "glacier" peaks like Titlis or the Jungfraujoch, the 50% discount is the standard benefit. This remains one of the best values of the pass, as it can save a single traveler over 50 Swiss Francs on a single excursion. Always remember to keep your pass handy (digitally or on paper), as you must show it both at the ticket office and often during the ticket inspections on the mountain lifts themselves.
