I am looking for some answers. We are staying in Lausanne and I am taking my girlfriend. We are trying to do a day trip to Montreaux to see the Chateau de Chillon and then come back through Vevey to see the Lavaux Vineyards. DO I need to buy a train ticket in advance? What kind of pass would I get? Do they have all day passes?
Second thing.. Is this possible to do both of these cities in one day? We would leave around 11am and we would have dinner in Vevey unless you recommend doing Vevey before Montreaux?
