The best day trips from Mykonos: ruins, quiet islands and slow ferries

Mykonos sits in the middle of the Cyclades like a glamorous ferry hub, and that is exactly how to use it. Within an hour's sail lie one of the holiest sites of the ancient Greek world, empty swimming coves and working island towns that feel a world away from the beach clubs. The island's own pleasures are real but quickly exhausted; its position is the thing nobody sells you on arrival. Here are the day trips worth your deck time, ranked — with the practical detail that decides whether each one actually works.

Key facts

• Boats to Delos leave from Mykonos Town's old port; the crossing takes roughly half an hour
• Scheduled inter-island ferries use the New Port at Tourlos, about 2km north of town — a different harbour entirely
• Tinos and Syros sit 15–30 minutes away; Paros and Naxos are typically 35 minutes to an hour and a half
• The meltemi wind can disrupt sailings in high summer — build in slack, and never plan a day trip for the day you fly home

Two ports, one wind, and the shape of a day

Mykonos has two harbours and they do different jobs. The Old Port, on the edge of Chora and walkable from most of the town, handles the Delos excursion boats, water taxis and the little sea bus that shuttles up the coast. Every scheduled ferry — Blue Star, Seajets, Fast Ferries, Golden Star — uses the New Port at Tourlos, a couple of kilometres north. Turning up at the wrong one with twenty minutes to spare is one of the most common ways a day trip dies before it starts. The sea bus links the two in a few minutes; a taxi is quicker, but taxis on Mykonos are thin on the ground, so leave more margin than feels sensible.

The second variable is the meltemi, the dry north wind that funnels down the Aegean through July and August and can blow hard anywhere from June to September. It rarely stops the big ferries, but it stops the small high-speed catamarans first, and those are precisely the boats that make Paros and Naxos feasible in a day. The wind also builds through the afternoon, which gives you one rule that applies to every trip on this list: take the earliest crossing out and accept an earlier return than you would like. A morning boat sails in conditions a late-afternoon boat may not.

Everything below assumes the warm half of the year. Delos boats generally run from early April to the end of November, with a much reduced service in December and effectively nothing through deep winter. June and September are the sweet spot — full schedules, bearable heat, fewer people on the Sacred Way.

1. Delos

Non-negotiable, and the reason to be here at all if you care about the ancient world. The uninhabited island next door was the mythical birthplace of Apollo and Artemis and later a cosmopolitan port city of real scale; UNESCO lists it as a World Heritage Site on the strength of its temples, mosaics, houses and the terrace of lions.

Boats leave the Old Port on most days at roughly hourly intervals through the late morning, typically around 10:00 and 11:30, with afternoon departures usually around 15:00 and 17:00 in high season. Mondays are the trap: the service is normally cut back to a single morning crossing, so a Monday that dawdles over breakfast has lost the day. Expect to pay around EUR 25 return for the boat and about EUR 20 for site and museum entry, with a concession rate of roughly half that. A half-day guided tour bundling boat, entry and a certified guide typically runs somewhere around EUR 79. Book a day ahead in July and August.

You usually get two to three hours ashore, which is less than it sounds. Walk the Sacred Way north from the jetty through the Sanctuary of Apollo first, while your legs are fresh, and reach the Terrace of the Lions above the dry Sacred Lake before the next boat's crowd lands. The lions standing there now are replicas; the weathered originals, dedicated in the late seventh or early sixth century BC, are indoors in the Archaeological Museum, which reopened in 2024 after a long restoration and is now worth real time rather than being somewhere to stand out of the sun. Then take the residential quarter below the theatre — the House of Dionysos with its mosaic of the god riding a tiger, the House of Cleopatra, the colonnaded courtyards where merchants from across the Mediterranean lived. Mount Kynthos, the low peak behind, repays the climb with the whole city laid out below, but attempt it only on an early boat and only if the heat is reasonable.

There is no shade, no village, no beach and no staying the night. Bring water, a hat and proper shoes; a small refreshment point near the museum is the extent of the facilities. The advice to take a morning boat still holds for light and heat — but it is worth knowing that the site now keeps long summer hours, so the last afternoon departure is a legitimate and far quieter option if you can handle low sun over broken marble, which is when the place looks best to us.

2. Rhenia

Delos's larger, equally uninhabited neighbour is the swim-stop of choice, and combining the two is, in our view, the best value day on the water here. The standard cruise runs about six hours: an hour or two among the ruins, a fifteen-minute sail across, then a couple of hours anchored off a sheltered cove with a sandy shore, clear water and nothing built on it, usually with a simple barbecue lunch of souvlaki, salad and wine included. Shared trips typically start somewhere around EUR 70 a head, and the Delos entry fee is usually extra rather than included — check before booking, because the difference is meaningful.

The honest caveat: a combined cruise gives the ruins short measure. If Delos is the point of your trip, take the standalone boat with a guide and do Rhenia another day, or not at all. If you want one good day that mixes substance with swimming, this is it.

3. Tinos

The easiest hop on this list and the one the Mykonos crowd forgets. Ferries typically run eight to ten times a day in high season, the crossing is often 15 to 30 minutes, and tickets typically start somewhere around EUR 10 — closer to a bus fare than a boat trip. What you get is a completely different Greece: a working pilgrimage island of dovecote-dotted valleys, marble villages and a food culture that Greek writers take seriously.

In Chora, the church of Panagia Evangelistria stands at the head of a long straight avenue climbing from the port. Thousands of pilgrims converge on it every 15 August, many completing the last 800 metres on their hands and knees along a carpet laid for the purpose, while the icon is carried in procession by naval officers — the same date on which, in 1940, the Greek cruiser Elli was torpedoed at anchor in this harbour. If you want the island rather than the spectacle, avoid mid-August entirely.

The interior is why you rent a car at the port; the bus network exists but is too thin to build a day around. Head north-west to Pyrgos, a village where doorways, fountains and lintels are all carved marble and where the Museum of Marble Crafts explains the quarrying and carving tradition properly. It typically opens mid-morning and closes in the early evening, and it is generally closed on Tuesdays, which has ruined more than one well-planned Tinos day. The Chalepas Museum nearby honours the sculptor Giannoulis Chalepas, who was born there. Inland, Volax sits in a valley of enormous rounded boulders nobody has satisfactorily explained, with a surviving basket-weaving trade.

For lunch, drop to the bay below Isternia and Thalassaki, a small seasonal restaurant on the old jetty that both Fodor's and the Greek Gastronomy Guide single out, and which draws speedboats over from Mykonos for the afternoon. Reserve — in summer it fills. Note the word seasonal: like much of Tinos, it shuts outside the warm months.

4. Paros

Fast ferries make Paros a straightforward day, typically 35 to 40 minutes, with tickets usually starting around EUR 30 and sailings most days of the week in season. Split the day between two towns and resist the urge to add a third thing.

Parikia, where the boat lands, is more than a transit port. Panagia Ekatontapiliani — the church of a hundred doors — is among the oldest surviving churches in Greece by the reckoning of Greek archaeologists, a serious Byzantine complex rather than a whitewashed chapel, and it stands a short walk from the quay. Behind it the old quarter climbs to a Venetian kastro built in the bluntest possible way, out of the marble columns and blocks of the classical temple that stood there, still plainly visible in the walls.

Then take the bus or a taxi north to Naousa, whose small Venetian harbour, half-sunk fort and ring of cafés is, in our view, the equal of anything on Mykonos at gentler prices. Barbarossa opened on that harbour in 1987 as a plain ouzeri and has since become an ambitious Aegean kitchen under the second generation of the family; it is popular enough that walking up and hoping is a poor plan. With an hour spare, the hill village of Lefkes inland gives you the old Byzantine paved trail and views across to Naxos.

What to skip: adding Antiparos. It is a lovely little island and a good idea on a Paros holiday, but on a day trip from Mykonos it turns a relaxed day into a forced march through two ferry timetables.

5. Naxos

The largest of the Cyclades and among the greenest — real farmland, real mountains, a cheese and potato economy rather than a tourist one. Crossings vary enormously, from about 35 minutes on a fast boat to roughly an hour and a half on a conventional one, so read your ticket carefully: the slow boat both ways eats three hours of daylight and turns a good day into a rushed one.

Chora delivers immediately. The Portara, the great marble doorway of an unfinished temple of Apollo, stands alone on its islet at the harbour mouth and is reachable on foot along a causeway; it is the photograph everyone takes and it deserves the reputation. Above the old town, the Venetian Kastro is a walled quarter you can still walk into, housing the archaeological museum and its Cycladic figurines.

If you rent a car — and on Naxos you should — the inland loop is the day. Halki, the island's former capital, is where the Vallindras distillery has been making kitron, the citrus-leaf liqueur peculiar to Naxos, since 1896; the short tour and tasting are usually free, and bottles typically run somewhere around EUR 15 to 25. Push on to Apeiranthos, a mountain village of marble lanes that feels older and stonier than anything on the coast. Eat Naxian graviera and the potatoes the island is known for wherever you stop.

Doable in a day, then — though be warned that Naxos is the island here most likely to make you resent your hotel booking back on Mykonos.

6. Syros

The administrative capital of the Cyclades is the connoisseur's pick and, conveniently, one of the closest: often 15 to 30 minutes, daily in season, with tickets typically starting around EUR 17. To our mind it is also the most weather-proof choice on this list, because it is a walking day in a town rather than a beach day, and it survives grey skies and a stiff meltemi perfectly well.

Ermoupoli was built in the 1820s by refugees from the War of Independence, who turned a natural harbour into one of the young Greek state's principal ports, and the architecture reflects that ambition rather than island modesty. Miaoulis Square is a broad marble plaza under palm trees, closed at one end by a neoclassical town hall designed by Ernst Ziller. Just off it, the Apollon Theatre was built in 1864 to a design by the Italian architect Pietro Sampo and consciously modelled on La Scala in Milan — an opera house on an Aegean island, still in use for the Festival of the Aegean and the Animasyros animation festival. Walk east into Vaporia, the shipowners' quarter, where grand houses drop straight into the sea beside the church of Agios Nikolaos.

Then climb. Ano Syros, the medieval Catholic settlement on the hill above, is a knot of stepped lanes leading to the cathedral of Saint George, and the view back down over the neoclassical town is the argument for the whole trip. Reckon on a steep twenty minutes or so on foot; take the bus up and walk down if the day is hot. Before the boat, buy loukoumi and halvadopita from the confectioners along the market street, and a wedge of San Michali, the island's hard, sharp cheese.

Fewer beaches, more elegance — and a rare Cycladic town busy with its own life rather than performing for visitors.

Fitting the trips into your stay

With one spare day, take Delos and nothing else. With two, add Tinos: cheapest, shortest crossing and probably the biggest change of register. With three, choose between Syros for a town day and Paros for a harbour day depending on the wind forecast, with Syros the safer bet if it is blowing. Naxos deserves a fourth day rather than a substitution, because it is the one that punishes a tight schedule.

One thing deliberately not on this list: the Santorini day trip. It is heavily marketed from Mykonos, it is expensive, it crosses some of the most exposed water in the central Cyclades on exactly the kind of catamaran the meltemi cancels, and it delivers a few crowded hours in Fira. Every option above gives you more for less.

As a rough budget, expect to pay somewhere around EUR 45 to EUR 70 for a self-organised Delos day including boat and entry, from about EUR 70 upwards for a combined Delos and Rhenia cruise, and roughly EUR 30 to EUR 80 in return ferry fares for the town islands depending on route and vessel. Add car hire on Tinos and Naxos, where it is close to essential.

Tip: Book Delos boats a day ahead in July and August, take the earliest departure you can stand, and check the following day's schedule the evening before — the meltemi rewrites timetables at short notice, and the small fast boats go first.

Stay for the sunsets; sail out for the substance.
