Do I need seat reservations for Swiss trains?

In Switzerland, seat reservations are generally optional on most trains, and you'll usually find enough available seats even during peak hours. However, it's a good idea to consider reserving seats, especially if you are traveling with a group and want to sit together. Go to Group Travel by Train for more information and contact details. 

Notably, for certain scenic routes like the Glacier Express and Bernina Express, seat reservations are mandatory to ensure you can fully enjoy the journey. These should be booked well in advance.

For the Golden Pass Line, seat reservations are optional but highly recommended, especially if you want to secure the best views and a more comfortable travel experience.

When exploring the picturesque Jungfrau region, there's no need for seat reservations. You can simply hop on board the trains in this area, making it convenient to explore at your own pace.
