The island of Delos is located near Mykonos, at the centre of the Cyclades archipelago, and is one of the most important mythological, historical, and archaeological sites in Greece. The excavations in the island are among the most extensive in the Mediterranean; ongoing work takes place under the direction of the French School at Athens, and many of the artifacts found are on display at the Archaeological Museum of Delos and the National Archaeological Museum of Athens.

Delos had a position as a holy sanctuary for a millennium before Olympian Greek mythology made it the birthplace of Apollo and Artemis. From its Sacred Harbour, the horizon shows the three conical mounds that have identified landscapes sacred to a goddess in other sites: one, retaining its Pre-Greek name Mount Kynthos, is crowned with a sanctuary of Zeus.
Although Delos has numerous secluded beaches, the main attraction has always been the archeological monuments found all over the island. From the Theater Quarter and the Sacred Way to the House of Masks and the Doric Temple of Isis, Delos is an archeological marvel brought into the modern era, that any history enthusiast worth his salt, should not miss out on.
 

There is no preferable time to visit the island as it has only around 20 inhabitants so it is never crowded throughout the year.

The best way to arrive at Delos from Athens is via a flight to Mykonos (45 minutes) as the island is too small to have its own airport. From Mykonos you can take a small boat to Delos and experience all that this gem of an island has to offer.
