After arriving from Athens, visit the Castalia spring. This is where the high priestess, or Oracle, would bathe to cleanse her body and soul. Next visit the Temple of Athena, with its unusual round, colonnaded thalos.

The Temple of Apollo was the center of this “navel of the world.” Nearby stands the restored treasury Athens built to house its offerings.
Athena Pronea

Offerings that were not pillaged from the various treasuries are collected in the Delphi Archaeological Museum. There you will see the famous bronze Charioteer statue, which still retains its inlaid glass eyes. Other attractions include the amphitheater and Asklipieion.

You can have a lunch of traditional Greek food in the nearby village, and on the way back stop in Arachova, popular for skiing and nightlife.
