Ferry from Ios to Andros is a longer Cycladic hop that links the lively southern island of Ios with the greener, more traditional island of Andros in the northern Cyclades, usually via a high speed or conventional ferry operated by Seajets or Golden Star Ferries. The distance is around 138 kilometres and typical travel times for this island to island journey are about 3 hours 10 minutes to 6 hours, depending on the exact route, stops and vessel. This connection is seasonal and does not run as frequently as central Cyclades routes, but it is a very useful link for travellers who want to combine Ios beaches and nightlife with Andros hiking, villages and quieter beaches without going back through Athens.
Key Information
Ferry duration
The average Ios to Andros ferry duration is reported at about 3 hours 10 minutes with Seajets, though that figure normally refers to the ferry leg itself rather than any changes you might need. For the reverse direction, Andros to Ios, Busbud gives a typical crossing time of around 6 hours for a direct ferry, covering about 138 kilometres. In practice you should expect a journey somewhere between roughly 3 hours and 6 hours depending on the company, routing and sea conditions.
Ferry companies
Ferries between Ios and Andros are mainly operated by Seajets, and aggregators specifically describe an Ios to Andros Seajets route with foot passenger and vehicle spaces available. Andros ferry guides also list Golden Star Ferries and Cyclades Fast Ferries as key operators serving Andros from Rafina and other Cycladic islands, highlighting that Andros sits on wider networks that also include Ios. Golden Star Ferries in particular runs many Cyclades routes linking Rafina with Andros, Tinos, Mykonos, Naxos, Paros, Ios and Santorini, so Ios and Andros often appear together within these seasonal schedules.
Fast vs slow ferry
On this route, Seajets offers high speed services with an average quoted sailing time of about 3 hours 10 minutes, which is relatively quick for the distance. Some conventional or multi stop sailings take around 6 hours, as indicated for the Andros to Ios direction, which reflects a slower ship or additional island calls. If speed is important to you, look for dedicated Seajets high speed connections; if you prefer a cheaper or more spacious crossing, a slower conventional ferry on a longer itinerary can be more comfortable even though it takes longer.
Best time to travel
The Ios to Andros ferry is very much a seasonal link, with the most reliable options appearing between late spring and early autumn when Seajets and Golden Star Ferries run extended Cyclades schedules. In peak season there can be at least 1 daily or several weekly crossings between Andros and Ios when you include all operators and directions, though exact days depend on the year’s timetable. In low season you may find no direct Ios to Andros sailings at all, in which case routing via Rafina, Naxos or Mykonos becomes necessary.
Sea conditions and wind
The sea between Ios and Andros runs through open parts of the Aegean and is exposed to the Meltemi, the strong northerly summer wind that can make crossings choppy in July and August. High speed ferries are more sensitive to these conditions, and strong winds can lead to slower journeys or occasional cancellations for safety. If you are prone to seasickness, choosing a morning departure on a larger vessel where possible and carrying motion sickness tablets is a sensible precaution for this route.
Port guide
In Ios, ferries for Andros depart from the main port of Gialos, which has ticket offices, cafés, tavernas, minimarkets and car rental agencies very close to the quay. Andros is served by the port of Gavrio on the west coast, the main ferry harbour for the island, with tavernas, small shops, car rentals and buses to Batsi and Chora (Andros Town). Both ports are easy to navigate but can be busy around departure and arrival times in high season, so arriving at least 45 to 60 minutes before departure is recommended.
Car rental advice
Ios has several car and scooter rental outlets around Gialos and in the Chora, so you can easily hire a vehicle for exploring the island before or after your sailing to Andros. Andros is larger, with many villages and hiking areas spread across the island, so hiring a car or at least a scooter is very useful to reach beaches, monasteries and trailheads from Gavrio. Seajets notes that vehicles are accepted on the Ios to Andros route, but spaces are limited, so book in advance and arrive early for boarding if you want to bring your car.
Foot passenger tips
As a foot passenger, aim to arrive at Ios port 30 to 45 minutes before your Ios to Andros ferry departure, or a little earlier in July and August when queues and traffic are heavier. Travel with manageable luggage because boarding may involve walking up ramps and using internal stairs to reach seats on high speed ferries. On arrival in Gavrio, you will find buses and taxis close to the ferry, but at busy times it is worth checking bus timetables in advance or arranging a transfer with your Andros accommodation.
Is this route worth it?
The Ios to Andros ferry route is very worthwhile if you want to experience two quite different sides of the Cyclades in one trip: Ios with its lively beaches and nightlife and Andros with its lush valleys, hiking trails and quieter villages. Travel times of roughly 3 to 6 hours are long enough to feel like a real journey but still fit into a single travel day, so you do not lose too much time in transit. For travellers who want variety and are happy to travel a bit further than the central Cyclades, this route adds a rewarding northern stop to an Ios based itinerary.
Alternative route if cancelled
If there is no direct Ios to Andros ferry on your date, the most practical alternatives involve travelling via a hub such as Mykonos, Naxos or Rafina. For example, you can sail from Ios to Mykonos or Naxos and then connect to an Andros ferry, or travel from Ios to Rafina or Piraeus and continue from Rafina to Andros, which has frequent services. In high season, there are many multi stop Cyclades itineraries, so you can usually find a combination of 2 ferries to bridge Ios and Andros even if your original plan changes.
Reverse route internal links
The reverse ferry route from Andros to Ios is clearly listed on several booking platforms, often with one daily Seajets sailing taking around 6 hours. Andros ferry guides emphasise connections via Rafina, Mykonos, Tinos, Paros and Naxos, all of which tie into routes that also serve Ios, making it easy to travel in either direction depending on your wider itinerary.
Frequently Asked Questions

Can I take my car on the Ios to Andros ferry?
Yes, Seajets information shows that vehicles are available on the Ios to Andros route, meaning you can take a car or motorbike on board. Vehicle places are limited, so you should reserve your car space when booking and arrive early at the port to complete boarding.
Is the Ios to Andros ferry affected by bad weather?
Like other Cyclades routes, the Ios to Andros ferry can be affected by strong Meltemi winds, with possible delays or cancellations when the sea is very rough.
