The Delos Day-Trip from Mykonos
How to combine the sacred island of Delos with a stay in Mykonos, why they are separate places, and how to plan the boat, the ruins and the afternoon.
Delos and Mykonos are two very different islands that share one short stretch of sea. Delos is the uninhabited, UNESCO-listed archaeological island — the Sanctuary of Apollo, the Terrace of the Lions and the mosaic houses — with no town and no overnight stay. Mykonos, just across the channel, is the lively Cycladic holiday island of beaches, windmills and nightlife, and the base from which almost everyone visits Delos. They are separate places with a boat between them, and our ticket covers Delos island admission only, not the crossing. This guide explains the difference, how the morning boat and timing work, and how to plan the ruins and the afternoon into one great day.
Are Delos and Mykonos the same place?
No — Delos and Mykonos are separate islands, a distinction worth being clear about when you plan. Delos is the small, uninhabited sacred island: an open-air archaeological site and UNESCO World Heritage Site with the Sanctuary of Apollo, the Terrace of the Lions, the merchant houses and their mosaics, the theatre and Mount Kynthos, plus the on-island museum, and nothing else — no town, no hotels, no nightlife. Mykonos is the larger, cosmopolitan holiday island next door, famous for its beaches, whitewashed town, windmills, Little Venice and buzzing summer scene. Our ticket, and the standard site ticket, admits you to Delos; the boat that links the two islands is arranged separately.
The two are complementary rather than interchangeable, which is exactly why the day-trip works so well. Mykonos gives you the comfort, the beaches and the base; Delos gives you one of the greatest concentrations of ancient history in the Aegean, experienced on an island with no modern overlay. Most visitors stay in Mykonos and cross to Delos for a morning, returning for the afternoon and evening. Our concierge recommendation is to treat Delos as a focused half-day of ruins and Mykonos as the rest of the day's pleasures, and to remember that your Delos ticket covers island entry only, with the boat crossing booked on top.
How does the boat and timing work for the day-trip?
The Delos day-trip is built around the boat timetable from Mykonos. Passenger boats leave the Old Port of Mykonos Town and cross to Delos in about thirty to forty-five minutes, with departures concentrated in the morning and the last return sailings in the early-to-mid afternoon. That schedule makes Delos a half-day trip by design: you sail over on an early boat, spend two to three hours on the island, and return for lunch. The crossing leaves from the Old Port, not the New Port where large ferries dock, so allow time to reach the right harbour, and always note the last return boat, as it is effectively your deadline on an island with few facilities.
Because your Delos entry is a timed hourly slot, the trick is to line it up with the boat you intend to catch. Our concierge recommendation is to choose one of the first crossings of the day for the coolest, quietest hours on the ruins, and to set your timed island entry to the hour your boat lands, so you step off the quay and go straight through the gate. Keep some flexibility in the windy summer months, when strong winds can lead operators to cancel sailings, and confirm the timetable in advance, as it changes by season. Booking the timed entry ahead, matched to an early boat, is what lets you plan the day-trip around the best hours on the sacred island.
What can I do in Mykonos around the Delos trip?
Because the Delos crossing is a morning affair, the rest of the day in Mykonos is yours, and the island offers plenty to fill it. After returning from the ruins, most visitors head for lunch in Mykonos Town or by the water, then spend the afternoon on one of the island's celebrated beaches, swimming and relaxing in a way the exposed, uninhabited Delos does not allow. In the town itself, the maze of whitewashed lanes, the famous windmills and the seafront quarter of Little Venice are made for a late-afternoon stroll, and the sunset and evening scene are a Mykonos institution. The contrast between a morning among ancient sanctuaries and an afternoon of Cycladic leisure is much of what makes the day so memorable.
Planning the day around this rhythm keeps everyone comfortable, especially in summer. Our concierge recommendation is to do Delos early, while the ruins are cool and quiet, and save the hotter, busier afternoon for the shade, food and swimming of Mykonos. If you have more than one day, you can keep a flexible slot in reserve in case wind disrupts the Delos crossings, and still enjoy Mykonos while you wait for a calm sea. This ruins-in-the-morning, island-in-the-afternoon pattern is the classic way to combine the two, and it lets a single day take in both the sacred history of Delos and the relaxed pleasures of Mykonos.
How do I plan a Delos and Mykonos day, step by step?
A smooth Delos-and-Mykonos day starts the night before, by confirming your boat crossing and your timed island entry so the two line up. On the day, make your way to the Old Port of Mykonos in good time for an early departure, cross to Delos in around half an hour, and step off the boat straight to the gate within your booked hour. Spend the next two to three hours walking the Sanctuary of Apollo, the Terrace of the Lions and the mosaic houses, adding the theatre and Mount Kynthos if energy and time allow, and finish in the shaded island museum. Throughout, keep the return-boat time firmly in mind, as it is the fixed end of your visit on an island with no town to linger in.
Back in Mykonos by early afternoon, the day opens out. Our concierge recommendation is to break for a leisurely lunch, then choose between the beaches and the town for the rest of the day, ending with the windmills, Little Venice and the famous sunset. Bring water, a hat, sunscreen and sturdy shoes for the exposed ruins in the morning, and pack a swimsuit for the afternoon. Because Delos is seasonal and normally closed on Mondays, and the crossings are weather-dependent, check the season and the boat schedule when you plan, and keep a spare day in the windy months. Securing your timed Delos entry in advance, matched to an early sailing, is what makes this classic Cycladic day-trip run without a hitch.
Frequently asked
Are Delos and Mykonos the same island?
No. Delos is the small, uninhabited archaeological island with the Sanctuary of Apollo, the Terrace of the Lions and the mosaic houses, and no town. Mykonos is the larger holiday island next door with beaches and nightlife, and the base for visiting Delos. A short boat links the two.
How do I do Delos as a day-trip from Mykonos?
Take an early passenger boat from the Old Port of Mykonos, a 30–45 minute crossing, and set your timed island entry to match. Spend two to three hours on the ruins and museum, then return on an early-afternoon sailing for lunch and the beaches of Mykonos.
Does my ticket include the boat from Mykonos?
No. The ticket is admission to Delos island only. You book the boat crossing separately with an operator, and we reserve your timed island entry to match your chosen sailing so you go straight to the gate when you land.
Can I visit Delos and still enjoy Mykonos the same day?
Yes — that is the classic plan. Delos is a morning trip because the boats are weighted to the morning, so you are back in Mykonos by early afternoon for lunch, the beaches, the town, the windmills and Little Venice. Do the exposed ruins early and Mykonos later.
How long does the whole Delos day-trip take?
Roughly a morning: about 30–45 minutes each way by boat plus two to three hours on the island, so you leave mid-morning and return in the early afternoon. The last return boat is your deadline, so keep an eye on the time as you explore.
Is Delos ever closed, and can weather stop the trip?
Yes. Delos is seasonal, open roughly April to October and normally closed on Mondays, and strong summer winds can lead operators to cancel the crossings. Check the season and boat schedule when you plan, and keep a flexible day in reserve in the windy months.
Can I stay overnight on Delos instead of Mykonos?
No. Delos has no hotels or town, so you stay in Mykonos (or elsewhere in the Cyclades) and visit Delos as a day-trip. This is why the boat timetable and the return sailing shape the whole visit.
