Overview
Delos, a UNESCO World Heritage Site, is one of Greece's most important archaeological sites and mythology's most sacred island. According to legend, this tiny uninhabited island was the birthplace of Apollo and Artemis. From the 9th century BC to Roman times, Delos served as a major religious sanctuary, commercial hub, and cultural center. Today, its extensive ruins cover the entire island, offering an unparalleled journey through ancient Greek civilization. The island is reached by a 30-minute ferry from Mykonos Old Port, where Little Venice and the Windmills await your return.
Excavation History
The site was first excavated by the French School at Athens beginning in 1872, and excavations continue to this day. Unlike Pompeii, no human remains or valuable items were found, suggesting inhabitants had warning and evacuated before the catastrophic eruption. Delos reached its peak as a religious and commercial center from the 3rd to 1st century BC. As Apollo's birthplace, it attracted pilgrims from across the ancient Greek world. The island also became the Mediterranean's major slave trading center under Roman rule, with an estimated 10,000+ slaves traded daily at its height.
Key Artifacts
The Terrace of the Lions features iconic marble lion statues dating to the 7th century BC (replicas stand on site; originals in the museum). The Temple of Apollo formed the island's religious heart as its sacred sanctuary. The House of Dionysus contains stunning floor mosaics depicting the god riding a panther. The House of Cleopatra preserves statues of wealthy merchants with impressive detail. The Ancient Theatre seated 5,500 spectators with harbor views. The Sacred Lake, now dried, is the mythological spot where Leto gave birth to Apollo and Artemis. Climb Mount Kynthos (113m) for panoramic Cyclades views.
When to Visit
Ferry departures: daily at 9 AM, 10 AM, 11 AM from Mykonos Old Port. Return ferries: 12 PM, 1:30 PM, 3 PM (the last boat is crucial -- miss it and you are stranded). Crossing time: 30 minutes each way. Best strategy: take the 9 AM boat, return on the 1:30 PM or 3 PM ferry, allowing 3-4 hours on the island. Season: April-October only (winter ferries suspended). Weather dependent: strong Meltemi winds cancel ferries, so check the morning of your trip.

Tips for Visitors
Book ferry tickets ahead: summer boats fill up, so book the day before at the Old Port office. Arrive at the port by 8:30 AM for the 9 AM ferry -- it leaves on time. Do not miss the return boat: the last ferry is at 3 PM, and if missed, a private boat costs €200+. Bring essentials: water (2 liters per person), snacks, sun protection, and comfortable shoes. There are zero facilities on the island -- no food, drinks, shade, or restrooms. The site is completely exposed, reaching 35°C+ in summer, so a hat is mandatory.
