Athens to Mykonos in 7 Days: The Sailing Route

Route Overview: Athens (Lavrion) to Mykonos

This one-way route runs from mainland Greece into the Cyclades over seven days and roughly 130 NM of open Aegean sailing. You pick up in Lavrion, 40 km southeast of Athens, and drop off in Mykonos. No doubling back. Each day pushes you further into the island chain, which is exactly the point.

Most charter companies in Lavrion, including Sunsail, Dream Yacht Charter, and several local operators, offer one-way arrangements to Mykonos. Build that drop-off surcharge into your budget from day one. A crewed catamaran in June 2026 runs roughly €3,200–€5,500 for the week before provisioning, while a bareboat monohull starts closer to €1,800. For a full breakdown, see our 2026 charter cost guide.

Day 1 , Lavrion to Kea: 15 NM

Pick up your yacht from Lavrion marina by midday. Provisioning is straightforward here: a Lidl sits 800 metres from the marina and there's a well-stocked chandlery at the port. Cast off by 14:00 at the latest. The crossing to Kea takes 3–4 hours under sail in a moderate breeze.

The channel between Cape Sounion and Kea funnels wind, particularly in the afternoon. Expect conditions 1–2 Beaufort above the open-water forecast. Head for Korissia, Kea's main harbour on the northwest coast. It has good holding in 4–6 m of sand, and you can take a taverna mooring stern-to for around €15–€20. If northerlies are pushing swell into Korissia, divert south to Vourkari, a snug inlet 1.5 NM further along. The waterfront tavernas there serve fresh grilled octopus for about €9 a plate.

Kea feels markedly different from the tourist-heavy Cyclades. Fewer than 2,500 people live here year-round, and you won't see cruise ship tenders. Walk 20 minutes uphill to Ioulis, the hilltop chora, to find the 6th-century BC Lion of Kea carved into the rock. Free, atmospheric, and completely uncrowded.

Day 2 , Kea to Kythnos: 15 NM

Another short hop, which leaves time to explore before you go. The passage south from Kea to Kythnos runs 15 NM and typically takes 2.5–3.5 hours. You'll cross the Kea-Kythnos strait, where wind can accelerate sharply. Check the 06:00 POSEIDON forecast from the Hellenic Centre for Marine Research before you leave.

Your destination is Loutra, a tiny harbour on Kythnos's northeast coast. The name means "baths," and the reason becomes clear the moment you arrive: thermal springs feed directly into the sea at the edge of the bay, emerging at around 52°C and mixing with the Aegean to create a natural warm pool. Anchor in 3–5 m off the beach in good sand holding, or take one of the 10 or so quay spots available. Loutra has two tavernas and a minimarket. Nothing more, nothing less.

If you want a wilder anchorage, Kolona beach sits on a narrow sand isthmus on Kythnos's west side. It's exposed to westerlies but excellent in settled weather. This is a good island to slow right down and enjoy having an anchorage almost to yourself.

Day 3 , Kythnos to Syros: 20 NM

Today's 20 NM passage is the longest so far and takes you past the western edge of the Cyclades toward Syros, the administrative capital of the island group. Depart by 08:00 to arrive with time to explore. In moderate conditions, F3–F4, you're looking at 4–5 hours on a beam reach. Genuinely good sailing if the Meltemi behaves.

Make for Ermoupoli, Syros's main port and the most architecturally striking town in the Cyclades. This was Greece's busiest port in the 19th century, and the neoclassical buildings, marble squares, and Apollon Theatre, modelled on La Scala in Milan and built in 1864, reflect that era's wealth. The municipal marina charges approximately €1.50 per metre per night, so a 40 ft boat pays around €18. Remarkably cheap by Mediterranean standards.

For dinner, skip the waterfront tourist strip and walk two blocks uphill to Mazi, where a full meal with wine runs around €20–€25 per person. Syros is also where you stock up properly: real supermarkets, a pharmacy, and ATMs on the main street. If anything on the boat needs attention, there are competent marine mechanics here, which is rare in the smaller Cyclades.

Day 4 , Syros: Rest Day or Delos Excursion

You've earned a day off the helm. Two options present themselves, and both are worth your time.

Option A: Rest in Ermoupoli

Explore the upper town of Ano Syros, a medieval Catholic settlement with labyrinthine alleys dating to the 13th century. The climb takes 15 minutes and rewards you with views across the entire harbour. After that, swim at Galissas beach (3 km by bus, €1.80 fare) or provision for the days ahead. This is your last reliable supermarket before Mykonos.

Option B: Day Sail to Delos

Delos lies 22 NM east-southeast of Syros. Check the forecast carefully before you go: this is open-water sailing, and conditions matter. Delos is one of the most significant archaeological sites in the Mediterranean, UNESCO-listed since 1990 and the mythological birthplace of Apollo. The ruins span 3,000 years. Entry costs €12. Landing is only permitted between 08:00 and 15:00, and no overnight stays are allowed.

Anchor off the west side in 5–8 m on sand and weed. Set your hook firmly. If the Meltemi is above F5, don't attempt this: the anchorage becomes untenable and the return passage unpleasant. Delos is for calm days only.

Day 5 , Syros to Mykonos: 25 NM

This is the big day. At 25 NM, it's the longest single passage of the trip, and the route runs almost directly across the Meltemi's path. Leave at dawn. 06:00 if you can manage it.

In July and August, the Meltemi typically builds from mid-morning, peaking between 14:00 and 18:00 at F5–F7, meaning 17–33 knots. An early departure means you cover most of the distance before conditions deteriorate. On a catamaran doing 7 knots, you'll be in Mykonos harbour by 09:30–10:00. On a monohull averaging 5.5 knots, expect arrival by 11:00.

Approach Mykonos from the south or southwest. The old port is chaotic with ferry traffic and generally unsuitable for yachts over 30 ft. Head instead for the new marina at Tourlos, 2 NM north of town. Berth fees are steep: expect €50–€80 per night for a 40 ft boat in high season, but you get power, water, and decent shelter from the north. Ornos Bay on the south coast offers free anchoring in 5–8 m with good sand holding, protected from the Meltemi by the island's bulk.

Day 6 , Mykonos

Leave the boat and explore on foot. The town of Chora is compact and walkable in under an hour, though you'll want longer. Little Venice, the row of 18th-century houses built directly over the water on the western seafront, is most photogenic before 09:00. The five whitewashed Kato Mili windmills, dating to the 16th century, stand just above.

For lunch, catch the bus from Fabrika Square to Agios Sostis beach on the north coast (20-minute ride, €2). Kiki's Tavern is a cash-only spot with no electricity that serves grilled pork chops and Greek salad for roughly €12–€15 per person. It opens at 12:30. The queue starts at 12:00. Arrive early. The beach itself is unspoilt and rarely packed, a stark contrast to the south-coast strips like Paradise and Super Paradise.

For a quieter swim, take the dinghy to Kapari beach, accessible only from the water. It's a 5-minute ride from Ornos anchorage and on a busy day you'll share it with perhaps 20 people. One note on costs: evening provisions on Mykonos run 15–25% more than on the mainland. Buy wine and staples back in Syros if the budget matters.

Day 7 , Hand Back and Head Home

Most charter companies require the yacht back by 09:00 on the final day. If you're berthed at Tourlos, the checkout process takes 30–60 minutes. A taxi from Tourlos to the old port ferry terminal costs €8.

Highspeed ferries from SeaJets, Minoan, and Golden Star run multiple daily services from Mykonos to Piraeus or Rafina. Journey time is 2.5–3 hours, and one-way deck tickets cost €55–€75 in 2025. Book ahead during July–August: ferries sell out. Mykonos airport (JMK) has direct connections to Athens (35-minute flight, from €45 one-way on Sky Express) and seasonal routes to London, Paris, and other European cities.

The Meltemi Factor

The Meltemi defines sailing in the Aegean. You cannot plan this route without understanding it. These strong northerly winds blow from roughly late June through mid-September, driven by a pressure gradient between a thermal low over Turkey and high pressure over the Balkans. They arrive under clear skies. You won't see them building on the horizon the way you'd spot a squall.

In the central Cyclades, sustained Meltemi conditions typically run F4–F6, with gusts to F7 common between islands where wind accelerates through channels. This is not dangerous for a well-prepared crew, but it is relentless. Seas build to 1.5–2.5 m with short, steep wave periods that punish flat-bottomed boats. A catamaran handles the chop better than most monohulls under 40 ft.

Practical Meltemi tactics

• Sail early. Depart by 06:00–07:00. Wind builds after 10:00 and dies after sunset.
• Use south-coast anchorages. The Meltemi blows from the north; the south side of any island is your lee.
• Monitor POSEIDON forecasts (poseidon.hcmr.gr) and the Windy app. Update twice daily.
• Carry a drogue or sea anchor. In sustained F6+, it gives you options if you can't make port.
• Accept rest days. If the forecast shows F7, stay put. A day in Syros or Kythnos harbour is not wasted time.

If the Meltemi sounds more stressful than enjoyable, book this route in late May, early June, or September. Winds are typically F2–F4, seas are gentle, and charter prices drop 20–40%. For a route with calmer conditions, Croatia's Dalmatian Coast rarely sees anything above F5.

Practical Planning and Budget

This route costs noticeably less than equivalent weeks in Croatia or the French Riviera, mostly because mooring fees and food prices in the smaller Cyclades are lower. Below is a realistic per-person, per-day breakdown for a crew of four on a bareboat catamaran.

Expense	Budget Tier	Mid-Range Tier
Charter share (boat + one-way fee)	€55/day	€90/day
Provisioning (cooking aboard)	€20/day	€25/day
Eating out (1 meal/day ashore)	€15/day	€25/day
Fuel (diesel + outboard)	€8/day	€10/day
Mooring / marina fees	€7/day	€15/day
Extras (entry fees, taxis, ice)	€10/day	€20/day
Total per person/day	€115	€185

Compare that to Croatia's Dalmatian Coast, where mooring fees alone average €40–€80 per night for a 40 ft boat. In the Cyclades, you'll anchor for free most nights. Restaurant meals in Kythnos or Syros run 20–30% cheaper than in Split or Hvar. For a detailed cost comparison, read our full 2026 pricing breakdown.

What to bring

The Cyclades are windier and drier than most Mediterranean sailing grounds. Pack UV-protective layers, a proper windbreaker (not a rain jacket: it rarely rains between June and September), and reef-safe sunscreen. Soft-soled deck shoes are essential on a catamaran's gelcoat. For the complete list, check our packing guide for sailing holidays.

Booking tips

• Book 4–6 months ahead for June or September dates. July–August fills by February.
• Hire a skipper if no one aboard holds an ICC or equivalent licence. Cost is €150–€200/day plus food, and it's mandatory for bareboat in Greece.
• Add skipper insurance (€40–€60 for the week) to reduce your security deposit from €3,000+ to as low as €500.
• Sort your return logistics before committing to one-way. Ferry tickets from Mykonos to Athens in August can hit €80+ if booked late.
