My husband and I will be arriving in Geneva on July 4th and want to take the train from the airport to Montreux for an overnight. Then we thought we'd take a train to Interlaken (or that area) and spend 2 nights and on the 7th a train to Basel where we'll catch the river cruise. I'm still confused about the trains, one site said not to buy a pass, another gave prices and mentioned the Golden Pass. The numbers when added up seem to support buying tickets individually. So should I get tickets at the airport or purchase ahead of time here in the states? Do I need a Golden Pass? We are interested in nature and sightseeing, not so much hiking, but we would like to take a tram or whatever to a mountain top on one of the days.
Any advice on Swiss train travel or places I've mentioned would be appreciated. Thanks.
