I'm planning a short stay with my parents in Switzerland near Jung-frau region. For that I've planned the following travel:
1. Domodossola to Grindelwald (Coming from Milan, Italy - First day)
2. Grindelwald to Jung-Frau peak and same evening return (Second day)
3. Grindelwald to interlaken, boating in Lake (Third day)
4. Interlaken to Basel (Third day evening)
What would you suggest me the best and cheapest ticket/pass for this fixed itinerary?
Thanks in Advance.
