Delos is one of the most significant archaeological sites in the Mediterranean — the mythological birthplace of Apollo and Artemis, a major religious sanctuary and trading center for over a millennium, and now an uninhabited island administered entirely as an archaeological park. It sits 2.5 kilometers from the western coast of Mykonos, visible from multiple points on the island. The ferry crossing takes 20 minutes; the site itself requires at least three hours to see properly and a full day to see well.
What Delos Is
Delos was one of the most important sacred sites in the ancient Greek world — a center of the Apollo cult and, from the 5th century BCE, a major commercial hub controlling trade across the Aegean. At its peak in the 2nd and 1st centuries BCE, it had a population of perhaps 25,000 people and was one of the wealthiest ports in the Mediterranean.
The site today contains the remains of temples, warehouses, private houses with intact mosaic floors, a theater, a sacred lake (now dry), and the famous Terrace of the Lions — a row of marble lion sculptures dating from the 7th century BCE. The archaeological museum on the island holds much of the sculpture and small objects found during excavation.
Getting There
The official ferry from the old harbor in Chora (Alefkandra) runs daily except Mondays, with multiple departures between approximately 9:00 and 13:00, returning in the afternoon. Journey time is 20 minutes. Tickets are purchased at the dock; there is no advance booking system. A combined ticket covering the ferry and the site entrance costs approximately €20 per adult as of recent seasons — verify current pricing at the port.
Boat trips from Mykonos that include a Delos stop also exist, but these typically give less time on the island than the official ferry service and are better suited to visitors with limited time.
How to Spend Your Time on the Island
The site is larger and more complex than most visitors anticipate. Allow a minimum of 3 hours; a full day is not excessive if you’re genuinely interested in the history.
Start at the Sanctuary of Apollo — the religious core of the island — then walk north to the Terrace of the Lions. The lions visible today are replicas; the originals are inside the museum. The House of the Dolphins and the House of the Masks, in the residential quarter, have the best-preserved mosaic floors on the site. The theater offers a view over the whole island and, on a clear day, toward Mykonos.
The on-site museum is small but excellent. It should not be skipped.
Practical Tips
- There is no shade on Delos. None. Bring a hat, sunscreen, and significantly more water than you think you need. The site is entirely exposed.
- The island has a small cafe and a bookshop near the entrance. Neither sells cold water by mid-afternoon — bring your own from Mykonos.
- The Monday closure catches many visitors off guard. The ferry does not run on Mondays; plan your visit accordingly.
- The last return ferry is in the early afternoon. Miss it and you are paying for a private water taxi. Check the final departure time before you enter the site.
- April, May, and October are the best months for Delos — the heat is manageable, the crowds are thin, and the light on the stone is excellent.
Why It Stands Out
Delos is not an add-on to a Mykonos trip. For anyone with even a passing interest in ancient history or archaeology, it is one of the primary reasons to be in this part of the Aegean. The scale and preservation of the site — and the strangeness of an entire inhabited island now reduced to ruins and administered as a park — make it one of the most memorable sites in Greece.
