Greece: Athens, Cyclades, and Crete
We spent 15 days island hopping from Naxos to Santorini to Crete, with stops in Athens at end end. We visited ruins at Knossos, Akrotiri, and Delos, hiked the Samarian Gorge, saw some beautiful beaches, and ate some delicious food. I think this is a great itinerary for a first visit to Greece.
