We are coming into Zurich on an overnight train, will pick up a car, and head towards Hohenschwangau. Our 2 boys (11 & 13) are going to need to stretch their legs after many hours on the train. Can you recommend stops and things to do between Zurich & Hohenschwangau? We are not in a hurry to get there (will spend the night & see castles next day). Just want to have fun on the way! Thanks!
