Start with a pick-up from your Athens hotel. Travel onward with your private driver along the Greek National Road through the plains of Boeotia and past Mt Parnassos to the UNESCO-listed sanctuary of Delphi, where your walk begins.   First, pass by Castalia Spring and spend your time viewing its many monuments. Admire the monument of the Argive kings, the treasury of the Athenians, the Athenian Stoa, the Polygonal Wall, the monument of Platea and the Temple of Apollo. Enjoy stunning views from the site, once considered by Ancient Greeks as the center of the world. Continue onward to the Delphi museum and view fascinating exhibits including a frieze of the Treasury of the Sifnians, the Naxian Sphinx, statue of Antinoos and the famous bronze sculpture of a charioteer. The exhibits complete the picture from the monuments seen earlier on your tour, and give further insight into the role Delphi played in bygone days. Although your itinerary is planned, you may customize it and stop in Delphi for lunch (optional).   Finish your meal and then relax in comfort as you travel back to your Athens hotel.
