We'll leave Athens Jan 4 for Delfi (the Oracle of Apollo) and stay overnight.  On Jan 5 we'll visit the Oracle of Zeus on the way to Metsovo, a mountain village (and ski resort) east of Ioannina, high in the Pindos Mountains.  On Jan 7 we'll go to Meteora, a group of monasteries perched on top of cliffs, and then to the port of Volos.  On Jan 8 we'll spend the day exploring the villages of Mount  Pelion above Volos.  We'll go to Athens for the 9th and 10th to see the Akropolis, Agora, and National Museum.  On the 11th we'll drive to Nafplion and visit Eleusis, Corinth, Mycenae, and Argos.  On the 13th we'll see the nearby island Spetses. After visits to Vasses and Olympia on the 14th we'll return to Athens on the 15th.
