Delphi

Delphi can be seen in a day trip from Athens (2.5 hours by car), enough to explore the sanctuary of Apollo and its famous oracle, considered in antiquity to be the «center of the world». April-June brings mild mountain weather ahead of summer heat. It's inexpensive compared to the Greek islands, with a more cultural than beach-focused tourism profile. Its Oracle of Delphi was for centuries the most important site of religious and political consultation in the Greek world, to which kings and city-states sent emissaries before making key decisions.
