Delos

Delos has no roads, no vehicles, and no internal transport of any kind — the entire archaeological site is explored on foot. The main path from the ferry dock loops through the key monuments and takes between 3 and 4 hours at a comfortable family pace. Wear sturdy walking shoes (not sandals or flip-flops — the ancient stone paths are uneven and the Mount Kynthos climb is rocky) and bring more water than you think you need, as there is no café or water point on the island. A site map is included with entry tickets and is well worth following.

Mykonos Town itself is entirely pedestrianised in the historic centre and very walkable — the harbour, windmills, Little Venice, and the main lanes are all within easy walking distance of each other. For reaching the beaches and the Old Port ferry dock from hotel areas outside Chora, the island has a reasonable local bus network (KTEL) with routes connecting Chora to the main beach areas and the airport; the main bus station in Chora has timetables posted and services run frequently in summer.

Taxis are available from the main stand near the bus station in Chora, and from the airport. During peak season, taxis can be in short supply — book ahead if you have an early morning Delos ferry departure to catch. There is no Uber or equivalent ride-hailing app on Mykonos; licensed taxis are the only option beyond buses and rental vehicles. Water taxis operate between the main southern beaches and are a fun way for families to move between beach spots during a beach afternoon.

Mykonos Town is best explored entirely on foot — the winding pedestrian lanes are part of the charm, and the town is compact enough to navigate without transport once you're based in Chora. For the Delos trip itself, realistic daily walking distances of 4–6 km on uneven ancient stone are normal; teens and adults with reasonable mobility will have no difficulty, but the site is not accessible for pushchairs or wheelchairs in its current form.

Delos is a day trip, not a multi-day stay — you cannot stay overnight on the island. Most families allocate one full day: take the first morning ferry from Mykonos Old Port, spend 3–4 hours exploring the site and museum, and return on a mid-afternoon boat. The ferry crossing is 30 minutes each way. Build in a relaxed evening in Mykonos Town afterwards and you'll have a very satisfying full day. Three or four days on Mykonos as a base gives you Delos plus beaches plus the town.

In my experience, yes — and this is coming from someone who has watched plenty of teenagers drag their feet through lesser ancient sites. Delos is different because it is an entire uninhabited island frozen in time, not a roped-off monument in a busy city. The Terrace of the Lions, the mosaics in the houses, and the panorama from Mount Kynthos all tend to land in a way that a standard museum visit does not. It works particularly well for teens who are into mythology, history, or photography, but even reluctant historians usually leave more impressed than they expected.

Yes, especially in July and August. The daily number of visitors to Delos is limited, and the boats fill quickly during peak summer weeks. I strongly recommend buying return ferry tickets at least a day or two ahead during peak season — tickets are available at the Old Port booth in Mykonos Town or from some hotels and online operators. In May, June, September, and October, same-day purchase is generally fine, but arriving early at the dock is still sensible.

This matters more than at almost any other site I've visited. Bring at minimum 1.5 litres of water per person (more in July/August), high-factor sunscreen, a sun hat, and proper walking shoes with grip — not sandals or flip-flops. There is no café, no water point, no shade, and no shop on the island. The site paths are ancient stone and can be uneven, particularly on the Mount Kynthos climb. A small backpack is ideal. The site's own map (included with entry) is worth studying before you set off from the dock.

Technically yes, but the site is not set up for pushchairs or young children who cannot walk reliably on uneven ground. The paths through the ruins are ancient stone and not paved or level; a baby in a carrier would work, but a pushchair would be very difficult. For families with toddlers, the ferry crossing plus the heat and exposed site can be exhausting. With children aged seven or eight and up who can walk independently and follow directions, it becomes much more manageable. Teenagers get the most from the visit.

Take the earliest available ferry, typically around 9:00am departure from Mykonos Old Port. This gets you onto the island before the midday heat and before the bulk of the day-trip groups arrive. By 11:00–11:30am in high summer, the island can be very crowded and very hot. Being on site for the first two hours of the morning, when the light is beautiful and the crowds are thin, makes the experience significantly better. Plan to return by early afternoon.

No. Delos is uninhabited and has no hotels, guesthouses, restaurants, or any form of overnight accommodation. The island closes to visitors in the late afternoon and the last ferry returns to Mykonos before sunset. All visitors must base themselves on Mykonos — the closest and most practical island, just 30 minutes by ferry from the Old Port. Some ferry operators also offer Delos as a day excursion from other Cycladic islands such as Paros or Naxos if you are island-hopping.

Delos is a remarkably safe destination for families. The archaeological site is well-managed by the Greek Ministry of Culture, entry is controlled, and the island's uninhabited status means there are none of the street hassle or petty crime concerns that can arise in busier tourist towns. The main practical safety note is environmental: the sun and heat on Delos are intense, and the island has zero shade and no water available. Pack sunscreen, sun hats, and at least 1.5 litres of water per person before boarding the ferry — this is not negotiable in summer. The ferry crossing can be choppy in strong Meltemi wind conditions (common July–August afternoons); families with children prone to seasickness should bring medication and aim for a morning sailing when seas are typically calmer.

For teenagers, Delos tends to be a genuinely engaging experience — the scale of what remains, the fact that you are walking through an actual ancient city rather than a reconstructed one, and the unusual atmosphere of an island with no permanent population make it feel different from a conventional museum visit. The UNESCO World Heritage designation opens good conversations about why certain places are preserved and what we owe to ancient history. Teens interested in mythology, history, or architecture will find the site particularly rewarding; even those who aren't typically engaged with history tend to respond to the lions terrace and the summit view.

~£120–£200/day mid-range (Mykonos; Delos admission ~£10-15 pp extra)

The gateway airport is Mykonos Airport (JMK), located approximately 3 km from Mykonos Town. From the UK, direct flights operate seasonally from London Heathrow, Gatwick, and Manchester; journey time from London is around 3.5–4 hours. Return flights from London typically range from ~£150–£450 per person depending on the season and how far in advance you book — July and August command peak pricing. A taxi from the airport to Mykonos Town takes around 10 minutes and costs in the region of ~£10–15; there is also a local bus service covering the main route.

Delos is reached exclusively by ferry from Mykonos Old Port. The crossing takes approximately 30 minutes each way. Scheduled departures run multiple times per day in peak season (roughly 9:00–13:30 outbound; 12:00–15:00 return), with reduced frequency in shoulder season and very limited service in winter. Return tickets cost around ~£20–25 per person including site admission in some packages, though it is common to buy the ferry and site entry separately. Book ferry tickets in advance during July and August — the daily visitor quota on Delos is managed and boats fill quickly. Tickets are available at the harbour ticket booths or through operators in advance online.

If you are travelling from Athens, Mykonos is served by high-speed and conventional ferries from Piraeus port. High-speed services (Hellenic Seaways, SeaJets) take around 3–4 hours; conventional ferries take 5–7 hours. This is a pleasant alternative to flying if you want to combine Athens with your Cyclades visit — families with teens often find the overnight ferry option (depart Athens late evening, arrive Mykonos early morning) a practical and adventure-adding way to travel.
