My wife and I will be staying 5 days mid July in Wilderswil outside of Interlaken after completing a river cruise from Amsterdam to Basal. I have been planning day trips as I will have purchased a first class Swiss Pass for our stay. After reading a few other threads the though came that we may want to take a day trip into Italy. Would love to hear any ideas in regards to this as to whether it would be worth a day and where would be the best to go and see. Also, I'm assuming that the Swiss Pass would only take us to the border then another ticket would need to be purchased. Any insight would be appreciated.
