Mehlweg Mountain
This is the mountain where the famous opening scene from The Sound of Music was filmed. I believe that the photo below is the hill that Julie Andrews did the spin on, but it was very cloudy and rainy on the day I took the drive, so it was hard to tell. The drive up the mountain was a bit difficult as the road was very narrow and often on the side of a cliff.
Eagle’s Nest
The Kehlsteinhaus (known as the Eagle’s Nest in English-speaking countries) is a Third Reich-era edifice erected atop the summit of the Kehlstein, a rocky outcrop that rises above the Obersalzberg near the town of Berchtesgaden. It was presented to Adolf Hitler on his 50th birthday as a retreat and place to entertain friends and visiting dignitaries. Today it is open seasonally as a restaurant, beer garden, and tourist site.
Werfen
This is where the mountain picnic scene from The Sound of Music (where they sing Do-Re-Mi) was filmed. Even with the clouds, the mountain in the background is clearly recognizable. There is a very easy hiking trail from the town center of Werfen that will take you to the filming location.
