This tiny, sacred place—the fabled birthplace of Apollo—is a testament to Greece’s glorious ancient civilization, home to one of the most fascinating and most important archaeological sites in Greece. When Delos was once a thriving sacred city—it was the religious center of the Cyclades—one could never be born or die on the island. Today the isle is unpopulated, but with a little imagination you can understand how a grand, ancient city once ruled the region. All you’ll find is ruins and you’ll have a few hours to explore them. Overnight stays are not allowed, and boats take you to the UNESCO World Heritage Site just for the day to explore the 5 km- (3 mile-) long island. The island has no shade, so don't forget to bring a hat, sunscreen and plenty of water.
Accessible only by boat from Mykonos town, unknown, Delos, Greece
