Do I need to make train reservations to get to Zermatt? I have a Swiss Pass.
Most Swiss trains don't require reservations, except a few named, heavily-marketed "scenic" routes. If you take an official Glacier Express departure that runs direct (with Observation Coach) between Zermatt and Chur or St. Moritz, then you will make a seat reservation for that entire train. Other regional trains running between Zermatt and Visp, where you change trains, do not require or even take seat reservations.
