Ferry from Ios to Lavrio is a long but very useful mainland connection for reaching Athens without going via Piraeus, linking the port of Ios (Gialos) with Lavrio on the south eastern tip of Attica. This route is normally operated once per week by Anek Superfast – Blue Star Ferries (often marketed together with Hellenic Seaways), and typical journey times sit in the 6 hours 25 minutes to 12 hours 10 minutes range depending on the exact schedule and any intermediate island stops. The distance is around 85 nautical miles or 158 kilometres, so this feels like a proper overnight or long day sailing rather than a short hop, but ticket prices can be very good value compared with other mainland routes. For travellers on Ios who want to travel directly towards Lavrio, Cape Sounion area or eastern Attica, this ferry route is a handy alternative to routes into central Athens ports.
Key Information
Ferry duration
The Ios to Lavrio ferry is the slowest of the main Ios–mainland links, with the reverse Lavrio to Ios direction quoted at about 12 hours 10 minutes as the typical crossing time with Blue Star Ferries. Some timetable summaries for the Lavrio–Ios line mention a duration range from about 6 hours 25 minutes to 12 hours 10 minutes, reflecting different itineraries and stops. Overall, when travelling from Ios to Lavrio you should plan for most of a day or an overnight trip on board, depending on the precise sailing.
Ferry companies
The Ios to Lavrio route is served exclusively on a scheduled basis by Anek Superfast – Blue Star Ferries, which operates one weekly sailing between the two ports. This is a conventional ferry capable of carrying vehicles and foot passengers and is part of a wider network of Blue Star routes linking Lavrio and Ios with other Cyclades islands. While Omio shows general Ios–Lavrio data, it also notes the service as essentially covered by a single daily direct ferry on some days, so availability is limited compared with Piraeus or Rafina routes.
Fast vs slow ferry
There is no dedicated high speed catamaran running only between Ios and Lavrio; instead the route uses conventional ferries that may call at several islands on the way. The “fastest” end of the reported duration range, around 6 hours 25 minutes, still counts as a long crossing by Cyclades standards. The longest sailings reach up to about 12 hours 10 minutes, which usually indicates multiple intermediate stops and overnight style itineraries, so travellers should treat this as a slow but comfortable conventional ferry crossing.
Best time to travel
The Lavrio–Ios line is shown as operating year round, with at least one weekly crossing in most months, and some sources describing it as available from January to December. However, the pattern is typically one morning departure per week from Lavrio (for example on Friday at 07:00), so the Ios to Lavrio return is also limited and concentrated on specific days. In practice this means you have less flexibility than with Piraeus or Rafina, so it is important to check the weekly pattern early when planning your itinerary.
Sea conditions and wind
The Ios to Lavrio route crosses the open Aegean and passes near several islands, so it can be affected by the strong Meltemi winds in summer. Conventional Blue Star vessels are generally robust and handle rougher seas better than smaller high speed craft, but strong winds can still slow the ship and cause arrival times to drift. Because this is a long crossing, any weather related delay can add a significant amount of time, so you should avoid very tight onward land connections from Lavrio.
Port guide
On Ios the ferry departs from the main port at Gialos, which serves all ferries to and from the island and is located about 17 kilometres from the island’s interior villages and main beaches. The port area has ticket offices, cafés, tavernas, small supermarkets and car rental agencies, making it easy to check in and wait for boarding. In Lavrio the ferry arrives very close to the town centre, with the port located roughly 1 kilometre from the centre, and there you will find bus connections, taxis, cafés and shops. Lavrio is also a convenient base for reaching Cape Sounion and onward travel to Athens and the wider Attica region.
Car rental advice
Ios offers plenty of car, quad and scooter rentals around Gialos and in the Chora, so many travellers drop off a rental vehicle before boarding the long ferry to Lavrio to avoid one way surcharges. In Lavrio, you can pick up a rental car either directly in town or from Athens airport or city locations after a short bus or taxi ride, which is useful if you plan to explore Attica or drive onwards. For travellers who want to bring their own car, fare examples on the Lavrio–Ios line show options such as two adults plus one car, so you can take a vehicle as long as you reserve a space in advance.
Foot passenger tips
As a foot passenger, you should aim to arrive at Ios port at least 45 to 60 minutes before departure for the long Ios to Lavrio sailing, especially in peak summer when boarding can be busy. Because the journey can last from about 6 hours 25 minutes up to 12 hours 10 minutes, pack a small bag with water, snacks, a light jumper and anything you need to stay comfortable on board. On arrival in Lavrio, check local bus timetables in advance if you are heading towards Athens, or pre arrange a taxi or transfer, as services may not always align perfectly with ferry arrivals.
Is this route worth it?
The Ios to Lavrio ferry is very worthwhile if you are heading to eastern Attica, Cape Sounion or want a more budget friendly mainland connection compared with some Piraeus routes. Ticket prices from Lavrio to Ios start from about €23.50 for a simple deck ticket in low season and are often among the cheapest ways to connect Ios with the mainland. The main trade off is time, as you need to accept a long journey, but in return you avoid the busier Piraeus port and arrive closer to Sounion and the Mesogeia area.
Alternative route if cancelled
If there is no suitable Ios to Lavrio ferry on your date, the main alternatives are to sail from Ios to Piraeus or Rafina instead and then travel by road to Lavrio or Athens. Ios has frequent high speed and conventional ferries to Piraeus and Rafina, which are much more flexible in terms of departure days and times. For travellers specifically wanting to reach Kea or Kythnos, another option is to sail from Ios towards those islands directly (when seasonal routes operate) or via Piraeus, rather than targeting Lavrio first.
Reverse route internal links
The reverse Lavrio to Ios route is clearly documented, with Blue Star Ferries running one weekly crossing that takes around 6 hours 25 minutes to 12 hours 10 minutes depending on the timetable. Ferry guides emphasise that Lavrio–Ios is a popular option for travellers going from the mainland to Ios and that it operates year round, albeit only once per week.

Is the Ios to Lavrio ferry affected by bad weather?
Like other long Cyclades crossings, the Ios to Lavrio ferry can be affected by strong Meltemi winds and rough seas, which may slow the ship and occasionally cause delays. However, the route uses large conventional ferries that generally handle adverse conditions better than small high speed craft.
Can I do a day trip from Ios to Lavrio and back?
Given that the journey takes between roughly 6 hours 25 minutes and 12 hours 10 minutes one way and there is usually only one weekly sailing, a same day return from Ios to Lavrio is not realistic. Travellers normally use this route as a one way leg at the start or end of their time on Ios rather than for short visits.
