The best vacations are often measured not by where one wanders, but by the friendships, the relationships, and the family bonds that one forges once there. The landscapes then act as mere vehicles for delightful moments.
A place is not enough. An open mind is also required to absorb the new social, cultural and visual signals that surround a traveler. Once this is understood, then it does not hurt to be absorbed by a unique topography, an ancient landscape, to be touched by a cool meltemi breeze, or to be lost in the azure ocean.
So then, where is the best place to visit in Greece? What is the absolute must-see locale? To answer the question one must define one's own interests first. Greece can offer an incredible gamut of activities.
The cultural and historical background of Greece has sprinkled the landscapes with ruins that span six thousand years. The alternating invaders, the peacefull settlers, and the country's position at the crossroads between east and west, have all left their mark on the Greek cultural landscape. Archaeological sites abound in the country side, and museums in cities protect priceless artifacts from antiquity. It would be an omission to visit Greece and leave without experiencing the ancient Greek culture; the culture that is credited with the birth of western civilization.
In reality, there is no such thing as "best Greek islands". One would definitely find a paradise among the 3000 islands of Greece. Searching is most of the fun of course, but here is a list to start with.
