In our upcoming trip we have one night booked in Garmisch-Partenkirchen and the next night in Salzburg and thought we'd spend a day getting from A to B by driving along the Alpine Road. The catch is, I'm hearing that this journey could take 6+ hours without stops for meals/scenery/attractions. We don't mind spending a few hours in the car, but that might be more than we're up for.
Does anyone have suggestions for a "modified Alpine Road" excursion? Are there sections of the road that are "must-see" and others that we could skip for faster/more direct routes?
For what it's worth, we're next traveling from Salzburg back to Munich (sounds crazy, I know, but it makes sense in the larger scheme of our trip) so we can go to Berchtesgaden on the way back without having to try to cram it into our day from Garmisch to Salzburg.
Thanks!
