Planning a Mykonos day trip from Athens is one of the most popular moves visitors make in Greece — and for good reason. The island delivers whitewashed lanes, genuinely good beaches, and a nightlife scene that starts late and finishes later. But the logistics matter enormously. Get the ferry wrong and you’ll spend half your day at sea. This guide cuts through the noise and gives you exactly what you need to make the trip work.
Getting to Mykonos: The Real Options
From Athens, you’re leaving from Piraeus Port — roughly 30 minutes from central Athens by Metro (Line 1, green line, €1.40 fare). Two main ferry operators run the Athens–Mykonos route: Blue Star Ferries and SeaJets. Blue Star runs conventional large ferries; SeaJets operates high-speed catamarans. There’s also the option of flying from Athens International Airport (Eleftherios Venizelos) on domestic carriers like Sky Express or Aegean — roughly 45 minutes airborne — but flights plus airport transfers often cost more time and money than a fast ferry. For a true day trip, speed matters most.
Blue Star Ferries
Blue Star is the workhorse of Aegean ferry travel. Tickets run €45–60 one way for a deck seat in 2026; cabin upgrades push higher. The journey takes approximately 5 to 8 hours depending on the route and stops — some sailings call at Syros or Tinos first, which stretches the trip considerably. Check your specific departure carefully on the booking page.
| Criterion | Blue Star Ferries | SeaJets |
|---|---|---|
| Cost | €45–60 one way | €60–90 one way |
| Time Required | 5–8 hours (route-dependent) | ~5 hours (express routes ~4.5 hrs) |
| Flexibility | Fewer daily departures, stable in rough seas | More frequent sailings, suspended in high winds |
| Best For | Overnight trips, budget travelers, seasick-prone passengers | Day-trippers, speed priority, peak-season flexibility |
The ships themselves are large, stable in moderate swell, and have cafeterias, lounges, and outdoor decks. If you’re prone to seasickness, the size helps. The main drawback for day-trippers is time: an 8-hour sailing each way makes a same-day return genuinely exhausting. Blue Star works better as an overnight option — book a cabin, arrive rested — or if you’re staying on Mykonos for several nights.

Departures from Piraeus for Mykonos typically leave around 07:30, but schedules shift seasonally. Book via the Blue Star website or Ferryhopper, which aggregates Greek ferry routes clearly. Book at least 4–6 weeks ahead in summer 2026; last-minute seats disappear fast on peak July and August sailings.
SeaJets
SeaJets high-speed catamarans are the practical choice for a genuine day trip. The crossing takes approximately 5 hours on standard fast-ferry services, though some express routes hit closer to 4.5 hours. Tickets cost €60–90 one way depending on how far ahead you book and which service you select. The tradeoff versus Blue Star is price and motion — smaller, faster vessels feel every wave, and anyone with seasickness sensitivity should come prepared with medication taken at least an hour before boarding.
SeaJets departs from Piraeus with multiple daily sailings in high season, which gives day-trippers genuine flexibility. An early morning departure (around 07:00–08:00) gets you to Mykonos Town by early afternoon, leaving several hours for beaches before a late-afternoon or evening return sailing. The New Port of Mykonos (Tourlos) is where most ferries dock — it’s a short taxi or shuttle ride from town.
Book direct via the SeaJets website or through Ferryhopper. If you’d rather bundle ferry plus a guided Mykonos day-tour (useful if you want someone else to handle the beach logistics), platforms like Viator and GetYourGuide offer organised departures from Athens that include transfers and island stops.
Booking Tips for 2026
July and August are relentless on this route. Ferries sell out — especially SeaJets fast services — weeks in advance. Book both outbound and return legs at the same time. Don’t assume you can grab a return ticket on the island; you often can’t in peak season.
Aim to book 6–8 weeks ahead for any July or August travel. May, June, and September are more forgiving — 2–3 weeks advance notice usually works — and the weather remains excellent. April and October sailings run on reduced schedules; double-check frequency.
Cancellation policies vary by operator and ticket class. Flexible fares cost roughly 10–15% more but allow date changes. If you’re travelling during a period when summer storms are possible (late August onward), the flexibility is worth it — high-speed ferries can be suspended in high winds, and Blue Star tends to operate when SeaJets can’t.
Which Option Should You Choose?
For a proper day trip from Athens in 2026, SeaJets is the better call. The faster crossing (around 5 hours) gives you actual time on the island rather than spending most of the day in transit. Yes, it costs more and the ride can be choppy — take seasickness tablets regardless of how confident you feel.
Blue Star makes more sense if you’re flexible on timing, want to save money, or plan to stay overnight rather than return the same day. The larger vessel is more comfortable, and the overnight cabin option is genuinely useful for anyone not rushing back.
If you want zero planning hassle, a structured day-trip package from GetYourGuide handles logistics cleanly — useful for first-time visitors who’d rather focus on Mykonos Town’s windmills and Psarou Beach than worry about port schedules.
