I went to both Berlin and Munich and somehow only managed to take 3 pictures, which is ridiculous. Anyway, this hike in southeast Bavaria, which will take you to the mountaintop border with Austria, is AWESOME and technically challenging. If you choose, you can add a hike down to the Eagles Nest from the Mount Goll summit and from there you can either head down the road or turn around and hit Mt Brett. I skipped the hike down to Eagles Nest. Views from above were good enough for me.
