Close by to the party island of Mykonos is the spiritual island of Delos. We were able to take a day trip there.
Delos is famous for being the birthplace of Apollo and Artemis. It was for a long time important for both being a religious center and for commerce (in part because of slave trade). Now it just serves as good reminder of a part of Greek history.
Stairway to highest point on Island.
It is customary to stack stones at the top.
