I will be travelling from Geneva to Interlaken, Zermatt and Bourg En Lavaux by car with 6 others in September. These are the things we want to do:
Harder Klum - Top of Interlaken
Train to Grindelwald and Gondola to Grindelwald First
Jungfrajoch
Sunnegga Furnicular to Sunnegga
Gornergrat Railway
Cable Car rode to Matterhorn Glacier
Cable Car to Glacier 3000
Boat Rides on Lake Geneva
Cogswheel Railway from Montreaux to Roches-de-naye
Wine train - train de vignes
Is there a pass we should buy that would give us discounts on these activities?
