Dietmar (Didi) N. is an exception guide, I would recommend using this young man with any tours desired but specifically within the Ober Salzburg and Berchtesgaden areas where our tour was conducted. Didi's first hand understanding of the areas noted and his extraordinary intuitive knowledge as a tour guide paid huge dividends in allowing us to view all the sites that were planned with-in the time frame afforded - accounting for weather, rush-hour traffic and the need to return to our Tauck vessel prior to its' departure.
