We are flying into Munich on 11th august. The flight gets in at 6 am. We are spending 8 days (including arrival day). Have a flight on 9th day at 3pm back from Munich. Traveling with 7 and 10 year old boys who don't care for music/arts and love outdoors, cable cars, mild hikes. I was wondering if someone can help with an itinerary.
Day 1: Munich hofbrau house, market place, viktualienmarket
Day 2; Deutsch museum
Day 3: rent car in morning from train station, drive to zugspitze, cable car up, sleep in furren/Ruette/garmisch
Day 4: kings castles, sleep in the same place
Day 5: drive to Berchtesgaden, visit eagles nest, sleep in Salzburg area (st. Gilgen/Salzburg/Berchtesgaden/bad ischl) for 4 nights
Day 6: Salzburg (fortress, Mozart birthplace)
Day 7: St. Gilgen/wolfgang (cable car, boat cruise)
Day 8: Hallstatt city walk + toboggan ride
Day 9: drive to Munich, return car, flight at 3pm
Is this too busy? How do I fit in ice caves and salt mines? Which ones should I go to? Anything I am missing or should skip? What are the best towns to stay for this itinerary
