Swiss Travel Pass covers Express trains?

Hi, Is my 4-day Swiss travel pass also valid for the Glacier Express and Bernina Express?

Hi Mariana and welcome to MySwissAlps!

Yes your Swiss Travel Pass covers those trains - except for a mandatory reservation fee. Click on the link to see what the pass covers (click the "where it's valid" tab).

Check out this page for more details on these 2 trains and how to buy the reservations.

Regards,
