Milos to Santorini Ferry: Boats, Times, Prices and How to Book

Ferries link Milos and Santorini through the season, leaving from Adamas on Milos and docking at Athinios on Santorini. Pick your boat based on whether time or money matters more.

How long is the ferry from Milos to Santorini?

The boat sets the crossing time. SeaJets runs the fastest service, a high-speed catamaran that reaches Santorini in just under two hours. Slower high-speed services take up to about 2½ hours. The big conventional ships, run by Fast Ferries, take roughly 4½ to 5 hours.

Some sailings go straight through, and others stop at an island or two along the way. Two departures at similar times can have very different journey lengths, so look at the full route before you buy.

How often do ferries run, and in what season?

Outside the summer peak, check the timetable before you plan around a specific day.

Which ferry should you take?

The conventional ferry is the comfortable, good-value choice when its departure time suits you and the longer trip doesn't bother you. It costs less, rides more steadily in rough water and has room to wander: open sun decks, a cafeteria and indoor lounges.

The high-speed boat saves two to three hours. The tradeoff is a bumpier ride in strong wind and, on the catamarans, enclosed airline-style seating with a small snack bar and no open deck. Large jets tend to feel more comfortable on the water than the small catamarans do. If you're prone to seasickness, choose a conventional ferry or a large jet.

How much does the Milos to Santorini ferry cost?

The slow boat is the budget option. Conventional fares run well below high-speed tickets, and VIP and business seats on the fast boats cost more again. Prices climb in July and August and keep rising as boats fill, so booking early saves money on any vessel. Bringing a car adds to the fare.

When should you book?

If your dates are set for July or August, reserve right away, especially when you need a particular sailing or space for a vehicle. Outside the busiest summer weeks, booking several weeks ahead usually works, and May, September and October tend to have more availability.

Tickets are sold online through the operators or a ferry comparison site, which lets you compare boats, stops, journey times and fares on one screen. Download your boarding pass before you reach the port.

Cars and motorbikes can travel on the conventional ferries and on some larger high-speed boats. Confirm that your rental company allows the car to travel between islands. If you're returning a rental car on Milos instead, check the return location and the agency's opening time.

How do you get to the ports?

In Milos, ferries leave from Adamas, the island's main port, a 2-minute walk from the village with its cafés, restaurants, hotels and shops. Hotels along the central waterfront are a 5 to 15 minute walk from the quay. If your hotel sits up a hill or out toward Papikinou Beach, expect a longer trek from the port when you are pulling bags.

A taxi or transfer from Plaka takes roughly 10 to 15 minutes, and from Pollonia allow 20 to 30. Milos has around a dozen licensed taxis for the whole island, so many visitors arrange a ride ahead of time when staying in Pollonia, Paleochori or along the south coast. Buses start and end at the main square in Adamas, about 492 feet (150 meters) from the ferry quay, which is roughly a minute away. Lines run year-round from Adamas to Plaka and Trypiti and to Pollonia, and summer routes add beaches like Paleochori, Sarakiniko and Provatas.

In Santorini, ferries dock at Athinios, the island's main port, about 5 miles (8 km) south of Fira at the foot of the caldera cliffs. The port is steep, busy and not walking-friendly. A single switchback road climbs to the rest of the island, and traffic backs up when several boats land at once. The Old Port below Fira is a different place, used by cruise tenders and smaller boats.

From Athinios you have three choices:

• Bus to Fira, a budget-friendly choice, though it gets crowded and is awkward with luggage.
• Taxi or pre-booked transfer, the easiest way to reach Oia, Imerovigli or any hotel outside Fira. Santorini has few taxis and port lines can be long. A reservation guarantees a vehicle, though not a traffic-free drive.
• Rental car pickup at the port, which is convenient but means driving straight into the Athinios traffic.

What should you bring on board?

Big suitcases go in a storage area near the ferry entrance, so hold on to your passport, medication, electronics and money. Ferries have cafés or snack bars, but bring water and a snack, and don't count on the Wi-Fi. Before leaving Milos, download your tickets, maps, transfer details and hotel information.

If you tend to get seasick, sit near the middle of the boat, put away your phone and any reading, and take medication ahead of time following the package instructions or your doctor's advice.

Can wind or strikes cancel the Milos to Santorini ferry?

The meltemi, the strong summer wind, can bring rough crossings, delays, vessel changes or cancellations, and the high-speed boats feel it most. Ferries that have already made earlier stops before reaching Milos are also more likely to run late.

Ferry strikes tend to show up around May 1, so check with your operator before you travel and keep that day's plans flexible.
