Just 30 minutes by boat from Mykonos’ old port, the island of Delos sits largely unchanged since the 7th century — a full ancient city with no modern layers built on top. For families used to the beach clubs and boutiques of Mykonos, it offers a direct encounter with the kind of history that usually stays in textbooks. The UNESCO World Heritage Site once housed 30,000 people and controlled much of the Aegean economy, a fact that hits differently when you are standing in the remains of the Theatre Quarter with your kids.
Yes, but treat it as a morning expedition with a clear payoff. The site has no shade and requires decent walking, so younger children need preparation. For history-curious kids aged 8 and up, the mosaics, theatre, and Terrace of the Lions make the effort worthwhile. Plan to return by early afternoon for beach time.
Ferries depart from Mykonos Old Port (Deliana port) several times daily between April and October. The crossing takes roughly 30 minutes. Morning departures run around 09:00, 10:00, and 11:00, with return boats operating until 17:00–19:30 depending on the season. A return ferry ticket costs about 25 EUR for adults, with reduced fares for children ages 6 to 12, while kids under 6 travel free. The site entry fee, which includes the Archaeological Museum, is 20 EUR for adults and 10 EUR for concessions.

If you prefer not to handle the logistics yourself, there are options for guided outings that combine ferry transfer, entry, and a licensed guide. A half-day guided tour typically runs 60–80 EUR per person and includes skip-the-line entry, which removes the queue for tickets on arrival. For families who want a guide without the fixed schedule of a group, archaeology-focused tours from Mykonos are worth browsing. Alternatively, you can book a day trip package that covers the basics and leaves the rest to you.
If you visit independently, buy your ferry ticket at the booth near Agios Nikolaos Church in the old port. Ask the return time when you purchase it — you can then plan your sightseeing around the scheduled departure.
The boat docks near the Agora of the Competaliasts, the old commercial centre where merchants sold perfumes and gems. From there, the Sacred Way leads to the Sanctuary of Apollo, a complex of three temples that once held some of the finest art in the ancient world. The most recognisable feature, the Terrace of the Lions, originally had nine marble guardians watching over the Sacred Lake. Four originals remain in the site museum, while replicas stand outside. The lake itself was drained in 1925 to stop mosquito breeding, which means it now looks like a dry depression — but the mythology of Apollo’s birth here remains central to the island’s identity.
The Theatre Quarter is where the wealth of ancient Delos becomes visible. The House of Dionysus contains a mosaic of the god riding a panther, still vibrant after 2,000 years. Nearby, the 5,500-seat theatre is carved into the hillside with direct views across to Mykonos. If you speak at normal volume in the centre of the orchestra, someone in the back rows can still hear you — the acoustics work that well.
For families with older kids, the climb up Mount Kynthos (113 metres) takes about 20 minutes and rewards you with a 360-degree view of the Cyclades, including Naxos, Paros, Syros, and Mykonos. The path passes the Grotto of Herakles and the remains of temples to Zeus and Athena.
| Option | Time on Island | Cost per Person | Best For |
|---|---|---|---|
| Independent visit | 2.5–3.5 hours | ~45 EUR (ferry + entry) | Families who prefer their own pace and pack their own lunch |
| Guided morning tour | 2–3 hours with guide, plus museum time | 60–80 EUR (ferry, entry, guide) | First-time visitors who want context behind the ruins |
| Delos & Rhenia cruise | 3 hours on Delos, then swimming stop | 70–120 EUR (includes lunch or BBQ) | Families wanting ancient ruins followed by a swim in clear water |
Worth knowingThe independent option gives you flexibility, but the guided tour brings the site to life. Without some background, the rubble can feel overwhelming. The combined Delos and Rhenia tour breaks up the archaeology with a swim — a smart move if your children’s attention span runs shorter than the Theatre Quarter requires.
The island has almost no shade. The combination of direct sun and reflected heat from the marble ruins makes July and August brutal. Bring at least one litre of water per person, high-SPF sunscreen, and a wide-brimmed hat. Flip-flops are a bad idea — the terrain is uneven and rocky, so trainers or hiking sandals are the better choice.
A small cafe near the museum sells water, snacks, and basic refreshments, but it is not a proper lunch stop. If you are spending more than two hours on the island, bring sandwiches and fruit. The museum itself is worth 30–45 minutes and holds the original Lion statues, frescoes, and pottery that help children connect the outdoor ruins to the objects people actually used.
The Meltemi wind can cancel boats in July and August. If your schedule is tight, book the earliest departure so you have time to rebook if needed. The Etesian winds are strongest in the afternoon, which is another reason to prefer the morning crossing.
Can we bring a stroller to Delos?
The site has uneven, rocky paths. A sturdy all-terrain stroller works for the main areas near the Agora and museum, but a baby carrier is better for the Theatre Quarter and any family members who want to climb Mount Kynthos.
Most families with children under 5 stick to the flatter sections and the museum, which is fully accessible.
Is there food available on the island?
A small cafe sells water, snacks, and basic refreshments, but don’t rely on it for a full meal. Pack sandwiches and fruit for a picnic near the Agora of the Competaliasts, where there are shaded stone benches.
Many guided tours that include a stop at Rhenia island provide a BBQ lunch on board, which solves the food problem entirely.
Are the afternoon tours too hot for children?
Afternoon excursions often mean 40°C heat plus strong sun reflection off the marble. The morning ferry, arriving around 09:30, is the sensible choice for families.
Evening tours exist but run only in peak season and leave you just two hours on the island, which is tight with kids.
What if the wind cancels our boat?
The Meltemi wind in July and August can ground ferries. If your schedule is tight, book the earliest departure so you have time to rebook if needed.
Independent ferry tickets are fully refundable up to 24 hours before departure, which gives you some protection.
Is the museum worth visiting with kids?
Yes. It holds the original Lion statues and everyday objects from the site. Seeing the mosaics up close here gives children context before they find the in-situ ones in the Theatre Quarter.
The museum is included in the site entry fee, so there is no extra cost to step inside for 30 minutes.
Delos leaves you with a different sense of the Cyclades — one that predates the white-washed cubes and infinity pools by two thousand years. It is worth the boat ride for that perspective alone. For more on how to structure your time on the island itself, visit the main Mykonos destination guide.
