If you have a Swiss Travel Pass, the actual ticket for the Glacier Express is fully covered; you do not need to buy a separate fare to ride the train. However, the Glacier Express is a premium "panoramic" train that requires a mandatory seat reservation, and this is NOT covered by the Swiss Travel Pass. You must pay a separate reservation fee, which varies depending on the season and the length of your journey. In 2026, these fees typically range from roughly 49 CHF in the winter to 59 CHF during the peak summer months. This fee ensures you have a guaranteed seat with the famous floor-to-ceiling windows. If you choose to dine on the train, meals are also an additional cost and are not included in the pass or the reservation fee. While you can technically take local regional trains on the same route for free without any reservation, they do not offer the same panoramic windows or direct service. To enjoy the full Glacier Express experience with your pass, you must go online to the official website and book your specific seat in advance, as the train frequently sells out during tourist seasons.
