Hi, we will be in Munich and really want to visit Eagle's Nest (mid to late August this year). Planning to have a rental car at that point in the trip. I'm aware you can't drive directly to the building. Looks like we will need to park at Obersalzberg - Dokumentationszentrum and take the bus/shuttle to Kehlsteinhaus.
For those who have driven from Munich, how long did it take (google says 2 hrs at 10pm via A8, with traffic in day time maybe 2.5-3hrs?), whether there are scenic stops along the way, should we stay off A8 and take a more scenic route (if so, what roads?), set GPS to non-tolls to stay in Germany or see more scenic routes, etc. I'm not asking how to get there, I'm asking if you have preferred routes. Also, we don't want to be in the car over 3-ish hours (one way) so trying to gauge travel time.
Thanks!
