I have planned a 4-day visit at Switzerland from Geneva to Bern then Zurich.
I checked the train fare that is relatively lower than the 4-day swiss pass (even include one Swiss Saver) because there has additional charges on the tickets even I book it with Swiss Pass (around USD12/person).
My questions are:
1. Is it worth to buy the Swiss Pass or I can just buy the tickets at the train station?
2. Can I walk around Geneva, Bern and Zurich without taking public transportation?
