We are a family of 4 who will be traveling in a VW van from visiting Neuschwanstein on a Friday afternoon to Garmisch. Google maps shows two possible routes: B17& B23 through Oberammergau or Fenpassstrasse/ B179 through Reutte/ Lermoos. Which route would be more scenic/better on May 24? My husband does have the international driving permit for driving in Austria and we know about the stickers. Your help is really appreciated.
