Santorini is roughly 300 kilometers southeast of Athens, floating in the Aegean Sea like something a movie set designer dreamed up. The caldera, the sunsets, the blue-domed churches — you already know what it looks like because it’s on every Greece travel poster ever printed.
The question isn’t whether to go. It’s how to get there.
You have two realistic options: ferry or flight. Both work. Both have trade-offs. And the “right” choice depends entirely on your budget, your schedule, and how you feel about open water. Here’s everything you need to make the call.
Quick Comparison: Ferry vs Flight#
| Ferry | Flight | |
|---|---|---|
| Travel time | 4.5-8 hours | 45 minutes |
| Price range | €35-75 | €50-180 |
| Frequency | 3-5 daily (summer) | 5-8 daily (summer) |
| Best for | Budget travelers, scenic experience | Short trips, time-limited travelers |
| Departs from | Piraeus or Rafina port | Athens Airport (ATH) |
| Arrives at | Athinios Port, Santorini | Santorini Airport (JTR) |
| Booking needed? | Yes, especially July-August | Yes, book 2-4 weeks ahead |
Option 1: Ferry from Athens to Santorini#
The ferry is how most people get to Santorini, and honestly, it’s part of the experience. Watching the Aegean islands slide past while the wind blows and the sun beats down — that’s the Greece you came for.
Ferry Types#
There are two kinds of ferries, and they’re very different:
High-speed ferries (4.5-5 hours) These are the catamarans and fast boats operated by SeaJets, Hellenic Seaways, and Golden Star. They’re modern, air-conditioned, and feel more like a bus ride than a boat trip. You’ll get an assigned seat (economy or business), there’s a café on board, and the ride is smooth unless the wind picks up.
Price: €55-75 one way.
Conventional ferries (7-8 hours) The big, slow boats — Blue Star Ferries runs the most reliable ones. These are massive ships with multiple decks, outdoor seating areas, restaurants, bars, and even cabins if you want to sleep. The journey takes longer, but you can actually walk around, sit outside, eat a proper meal, and enjoy the ride.
Price: €35-50 one way (deck/economy class). Cabins cost more.
Which Port: Piraeus or Rafina?#
Piraeus is the main port and where most Santorini ferries depart from. It’s connected to central Athens by metro (Line 1, green line — about 45 minutes from Syntagma). Most departures are early morning (7:00-7:30 AM), so plan accordingly.
Rafina is a smaller port on the east coast of Attica. Some high-speed ferries depart from here. It’s closer to the airport (about 20 minutes by car) but farther from central Athens (about 1 hour by KTEL bus from Pedion Areos).
Bottom line: Unless you’re coming straight from the airport, Piraeus is easier.
Ferry Schedule & Booking#
In peak season (June-September), there are 3-5 ferries daily to Santorini. In winter, that drops to 1-2 daily, sometimes fewer.
You can compare schedules and book tickets on ferry booking platforms. The major ferry companies also sell directly through their own websites:
- Blue Star Ferries (bluestarferries.com) — conventional ferries, most reliable
- SeaJets (seajets.gr) — high-speed catamarans, fastest option
- Hellenic Seaways (hellenicseaways.gr) — mix of fast and conventional
- Golden Star Ferries (goldenstarferries.gr) — high-speed
Arriving at Santorini by Ferry#
Ferries dock at Athinios Port, which is at the bottom of the caldera cliffs. It’s not in Fira (the main town) — you’ll need to get up the cliff and across the island. Options:
- Bus: €2.50 to Fira, runs timed with ferry arrivals. Cheap but crowded.
- Taxi: €25-30 to Fira, €35-40 to Oia. Pre-book in summer — the taxi queue at the port is legendary.
- Pre-booked transfer: €15-20 per person for shared shuttle. Most convenient if you book in advance.
What to Bring on the Ferry#
- Layers — the air conditioning on high-speed ferries is aggressive, and the outdoor decks on conventional ferries get windy
- Snacks — onboard food is fine but overpriced
- Motion sickness tablets if you’re prone (the Aegean can get choppy, especially in the afternoon)
- A power bank — outlets are limited
Option 2: Flight from Athens to Santorini#
If your time is limited, fly. A 45-minute flight versus a 5-8 hour ferry makes the math pretty simple when you only have a few days.
Airlines & Prices#
Three airlines operate the Athens–Santorini route:
- Aegean Airlines — Greece’s full-service carrier. Reliable, comfortable, includes carry-on. Prices: €60-150 one way.
- Olympus Air (by Aegean) — Regional subsidiary. Same aircraft, sometimes lower prices. €50-120.
- Sky Express — Small regional airline. Turboprop aircraft, cheaper fares. €40-100. Less legroom, but it’s 45 minutes.
- Ryanair — Seasonal summer flights. €30-80 when available. Budget carrier rules apply (extra for bags, check-in, etc.).
Santorini Airport (JTR)#
Santorini’s airport is tiny. Like, “the arrivals hall is the size of a coffee shop” tiny. There’s one runway, no jet bridges, and during peak season it’s controlled chaos.
Getting from the airport to your hotel:
- Bus: €1.80 to Fira. Runs roughly every 30 minutes. Cheap but can be standing-room-only.
- Taxi: €20-25 to Fira, €30-35 to Oia. Limited taxis — prepare to wait.
- Pre-booked transfer: €15-20 per person. The smartest move in summer.
- Rental car: Available at the airport. Book well ahead for summer.
Flight vs Ferry: The Real Math#
A €60 flight sounds cheaper than a €60 high-speed ferry, right? But factor in the full picture:
| Cost Factor | Ferry | Flight |
|---|---|---|
| Ticket | €35-75 | €50-180 |
| Getting to departure point | €1.20 (metro to Piraeus) | €10 (metro to airport) |
| Time at departure point | 30 min before | 1.5-2 hours before |
| Checked baggage | Free | €0-30 extra |
| Total cost | €36-76 | €60-220 |
| Total time (door to door) | 6-10 hours | 3-4 hours |
The flight wins on time. The ferry wins on cost and flexibility (more departure times, no bag fees, no airport hassle). If you’re traveling with large luggage, the ferry is significantly easier.
My Recommendation#
Take the ferry if:
- You have a full day to travel
- You’re on a budget
- You want the experience of sailing across the Aegean
- You’re traveling with large bags or lots of stuff
- You’re already near Piraeus
Fly if:
- You only have a few days total in Greece
- You value time over money
- You’re connecting from an international flight through Athens
- The sea makes you queasy
The sweet spot: Take the high-speed ferry one way (morning departure, arrive by lunch) and fly back to Athens (save time for your return flight home). Best of both worlds.
When to Go: Santorini by Season#
| Season | Ferry Frequency | Flight Frequency | Prices | Crowds |
|---|---|---|---|---|
| Peak (Jul-Aug) | 4-5 daily | 6-8 daily | Highest | Packed |
| Shoulder (May-Jun, Sep-Oct) | 3-4 daily | 4-6 daily | Moderate | Pleasant |
| Off-season (Nov-Apr) | 1-2 daily | 1-2 daily | Lowest | Quiet |
Frequently Asked Questions#
How far in advance should I book?#
For summer (June-August): Book ferries 1-2 weeks ahead, flights 3-6 weeks ahead. For shoulder season: A few days to a week ahead is usually fine.
Can I do Santorini as a day trip from Athens?#
Technically possible with a morning flight out and evening flight back, but I wouldn’t recommend it. Santorini deserves at least 2-3 nights. The sunset alone is worth staying for.
Do ferries run in bad weather?#
Strong winds (meltemi) can cancel ferries, especially high-speed ones. This happens most in July and August. Conventional ferries are more resistant to weather. If your ferry gets cancelled, the company will rebook you on the next available boat or offer a refund.
Is there a night ferry to Santorini?#
Blue Star Ferries occasionally runs evening departures that arrive early morning. These are the conventional (slow) ferries. You can book a cabin and sleep on board — it’s actually a good option if you want to save a night of hotel costs.
Should I book a cabin on the conventional ferry?#
For the day crossing? Not necessary — grab an outdoor deck seat and enjoy the views. For a night ferry? Yes, absolutely. The airplane-style seats are not comfortable for sleeping.
Getting Around Once You’re There#
Santorini isn’t big, but it’s not walkable between towns. Here’s how to get around:
- Local buses: Connect Fira to all major villages. €1.80-2.50 per trip. Reliable but crowded in summer.
- Rental car/ATV: The most freedom. ATVs are popular but the roads are narrow and tourist-accident rates are high. If you rent, get a small car instead.
- Taxis: Expensive and scarce. Santorini has maybe 25 taxis for the whole island. Pre-book or use the taxi stand in Fira.
- Walking: Fira to Oia is a beautiful 10km clifftop hike (2-3 hours). Do it.
