So, you tell us, all you need for your stay is two tickets, from Zurich Airport to Fürgangen-Bellwald Talstation and back? No need for further tickets during your stay?
It’s either two single point-to-point tickets or a Saver Day Pass for each travel day, whatever is less costly. The latter’s price depends on availability and demand. Tickets and Saver Day Passes are available 60 days out. All prices might be a little bit higher than indicated now, as there will be a raise in ticket prices with the yearly timetable change in December 2023, as communicated earlier this month by the public transport alliance.
