With the 4-days Swiss Pass we enjoyed ourselves enormously, getting on and off trains as we pleased, making the most of each day, and doing things for fun free of additional charges.
We explored Zürich, Lucerne, Lugano and Bern, we went up Mt Stanserhorn and Mt Rigi by cable cars, we took boat trips on Lake Lucerne and Lake Lugano, and visited Einstein and FIFA museums.
Absolute amazing value for the money spent on the pass!
