Lowest fares shown on Ferryhopper's Milos - Koufonisia route page when we checked on 2026-09-24. Fares change with the date, vessel and demand; the booking page shows the current price for your date. Each figure is the lowest for that party on the date checked, and the rows may come from different sailings, which is why two adults on this direction cost less than twice the single fare. Monthly fares for Koufonisia to Milos ranged from €107.70 to €116.70. There are no car fares because the boats carry no vehicles.

The Journey

The Koufonisia to Milos (Adamas) crossing.

This crossing takes you from one end of the Cyclades beach scene to the other: from the shallow turquoise bays of Koufonisia in the Small Cyclades to the volcanic coastline of Milos in the south-west, some 55 nautical miles away. It is a popular way to finish a trip that started in the Small Cyclades, because Milos has an airport and frequent boats back to Piraeus.

Only Seajets sails the route, and only between April and October. How often depends heavily on the month. Ferryhopper's monthly table for Koufonisia to Milos, based on last year's data, shows one sailing a week in April, six days a week in May, five in June, three in July, two in August, and a daily boat in September and October. Midsummer, oddly, is the thinnest time.

It is a long ride for a fast boat, about 4 hr 20 min at best and up to 5 hr 20 min in June and July, and fares are high: Ferryhopper listed one adult from €107.70, with monthly prices up to €116.70. Our older route data quoted fares from €40 and a four-hour crossing; Ferryhopper's figures do not support the €40 fare, so use the booking page for the real price on your date.

Koufonisia is a walk-everywhere island, so getting to the boat is simple. The effort goes into choosing the right day. If the direct boat does not run when you need it, Naxos and Paros both have ferries to Milos and short links from Koufonisia.

How long the crossing takes

In Ferryhopper's monthly figures for Koufonisia to Milos, based on last year's data, the crossing took 4 hr 20 min in August, 4 hr 30 min in April, May, September and October, and 5 hr 20 min in June and July. So allow about 4 hr 20 min on the quickest sailings and more than five hours in early summer. Ferryhopper's general summary for the pair of islands puts it at about 4 to 4 hr 50 min, so the exact time depends on the sailing; the booking page shows each departure's arrival time. The distance is about 55 nautical miles (102 km).

04The ports

Where the Koufonisia to Milos (Adamas) ferry docks.

Departure port

Koufonisia

KOU · 36.9333° N 25.6000° E

You board in Chora, the village on the southern shore of Pano Koufonisi, where the harbour sits right in the settlement. Most people walk to the quay with their bags; the island is small, and people get around on foot or by bicycle. Cafés, restaurants, shops and hotels are close to the port, and Ammos beach is a short walk away if you have time for a last swim. Several boats can call at the small quay around the same time in summer, so check the vessel name on your ticket and be ready early: fast boats do not wait long.

Arrival port

Milos

MLO · 36.7256° N 24.4489° E

You arrive at Adamas (Adamantas), the port of Milos, set in the calm water of the island's big bay on the north coast. The port and village run into each other, with restaurants, cafés, shops and car rental offices by the quay, so you can pick up a hire car the moment you land. Plaka, the capital, is about 5 km away. Milos is spread out and its best beaches are far apart, so if you are not hiring a car, arrange a transfer or check the bus with your accommodation before you arrive.

05On Board

On board the Koufonisia to Milos (Adamas) ferry.

For four to five hours you will be on a Seajets high-speed boat: enclosed air-conditioned lounges with allocated seats, and a snack bar or café selling drinks and light food. There are no cabins. Most boats have a Wi-Fi hotspot. Seajets allows up to 50 kg of luggage per passenger free of charge, and nobody checks it in: you carry it on and stow it yourself. Pets travel free on this route, but check the company's pet rules and bring health certificates. The long run with few outside areas is worth preparing for with water, snacks and something to read.

06Weather and cancellations

Wind, weather and cancellations on the Koufonisia to Milos (Adamas) route.

A long high-speed crossing across open water is the kind most exposed to the meltemi, the north wind that peaks in July and August. On rough days the boats can run late or be held in port by the port authority. If your sailing is cancelled, Seajets will rebook or refund you, but with only two or three sailings a week in midsummer the next direct boat could be several days later. That is the main reason to keep a spare day before any flight from Milos, and to know the Naxos and Paros alternatives.

07Travel Tips

Koufonisia to Milos (Adamas) ferry travel tips.

  1. Aim for September or October if you can: last year there was a boat every day, against two a week in August.

  2. If you plan to fly home from Milos, leave at least a day between the ferry and your flight.

  3. You cannot take a car, so hire one on Milos after you land; the rental offices are by the port in Adamas.

  4. Take water and snacks: at best this is a crossing of 4 hr 20 min.

  5. No direct boat on your day? Look at Koufonisia to Naxos and Naxos to Milos instead.

08Alternatives

Other ways between Koufonisia and Milos (Adamas).

For the trip in the other direction, see our Milos to Koufonisia page. Koufonisia has no airport; Milos does (MLO), and Naxos (JNX) is the nearest airport to Koufonisia. When the direct boat is not running, go from Koufonisia to Naxos and on to Milos, or from Koufonisia to Paros and then Paros to Milos, checking that both legs run on the same day. In winter the only practical route is via Piraeus, with Koufonisia to Athens and then Athens to Milos.

Questions

Koufonisia to Milos (Adamas) ferry: frequently asked questions.

  • About 4 hr 20 min to 5 hr 20 min on the Seajets high-speed boats, based on last year's monthly data for this direction. The quickest sailings were in August, and the slowest, around 5 hr 20 min, in June and July. Check the arrival time for your specific departure.

  • Ferryhopper showed one adult from €107.70 when we checked on 24 September 2026, and €190 for two adults. The monthly table put Seajets fares on this direction at €107.70 to €116.70. There is no cheaper conventional ship on the direct route.

  • Only from April to October. Last year Seajets sailed once a week in April, six days a week in May, five in June, three in July, two in August and every day in September and October. Nothing was listed between November and March.

  • Only Seajets, with high-speed boats. No conventional ferry runs directly between the two islands, so on days without a Seajets sailing you will need to change boats, usually at Naxos or Paros.

  • No. The Seajets boats on this route have no car deck, and Ferryhopper shows no vehicle fares. You will not need a car on Koufonisia anyway, and on Milos you can hire one from the offices by the port in Adamas.

  • No direct one. The Seajets route runs from April to October. Between November and March, the practical way is via Piraeus: Koufonisia to Athens, then Athens to Milos, which takes a full day or more depending on the connections.

  • Yes, particularly in July and August, when last year there were only three and two sailing days a week. With one operator and no backup boat, book as soon as you know your dates, and before you book your Milos accommodation.

  • From the harbour in Chora, the main village of Pano Koufonisi, on the island's southern shore. Most visitors walk there. Cafés, restaurants and shops are close by, and Ammos beach is a short walk from the quay.

  • At Adamas, also written Adamantas, the port village in the big bay on the north side of Milos. Restaurants, cafés, shops and car rental offices are right by the quay, and Plaka, the capital, is about 5 km away.

  • Seajets will offer another date or a refund. On a long high-speed crossing like this, meltemi winds in July and August are the usual cause. Because the direct boat may not run again for a few days in midsummer, the quickest way on is often via Naxos or Paros.

  • Yes, Milos has an airport (MLO), which makes it a handy last stop. But with a crossing of 4 hr 20 min or more and few sailing days in summer, leave at least a full day between the ferry and your flight in case of weather.

  • Yes, Seajets runs Milos to Koufonisia from April to October in about 4 hr 5 min to 4 hr 50 min, with one adult from €95 on Ferryhopper when we checked. See our Milos to Koufonisia page.
