We've got the chance this year to go away outside of school holidays for the first time with 2DCs (18 and 16). I spent time living in Germany and France in my teens and really miss the scenery. I'm trying to plan a driving holiday for around 10 days at the end of June/beginning of July that will take in gorgeous scenery (lakes and mountains) as well as activities for that age (ziplining/kayaking). I'm a bit lost about where to start! Any suggestions either of activities or must-see locations would be really helpful, and any recommended accommodation. Thanks!
