No trip to Southern Germany would be complete without seeing the infamous Eagle's Nest (Kehlsteinhaus) built for Adolf Hitler's 50th birthday in 1938. While the structure was rarely visited by Hitler, it remains a symbol of the Nazi excesses of the period. A restaurant occupies most of the house, and is not particularly interesting. The views, however, are spectacular. A trail from the house leads to a ridge with awe-inspiring overlooks of nearby peaks. The famous Edelweiss Cross is halfway along the trail. Built in 2003, it is stunning and is a favorite picture stop for visitors.
