Eagle's Nest Road - Kehlsteinstrasse
The Eagle's Nest road or Kehlsteinstrasse is considered to be a unique architectural masterpiece and a true feat of engineering: in a single hairpin bend, the tremendous 700 metres (2,297 feet) in elevation between Obersalzberg and the Eagle's Nest parking lot are climbed, passing twice through the steep north-west face of Mount Kehlstein.
