We heard the train ride from Zurich to Salzburg via innsbruk is very scenic. So we will be in Zurich for 5 nights and one of the days we plan to goto Salzburg and return next day.. and visit ice caves plus Untersberg. Considering the train journey each way is 5.5 hours almost, is this worth the trip?
note we are travelling with a 5 year old.
We already have a hectic schedule while staying in Zurich with day trips to Jungfrau, Lucern.
Please advise if the trip will be worth it
