Greek Islands Ferry Guide 2026: All Mainland–Island and Island–Island Routes

Greece boasts one of the world's busiest domestic ferry networks. Ships departing from Athens' ports connect hundreds of islands, from the Cyclades to the Dodecanese, and from the North Aegean to Crete. This guide covers Greece's domestic ferry network for the 2026 season — connections between the mainland and islands, and between islands themselves — group by group, operator by operator. We have a separate guide for routes departing from Turkey; here, the focus is entirely on Greece's domestic network. Our island guides: Rhodes travel guide, Kos travel guide, Patmos travel guide.

Coming from Turkey? This article describes Greece's domestic ferry network. To learn how to travel from Turkish ports like Bodrum, Çeşme, Kuşadası, Marmaris, and Ayvalık to the Greek islands, see our Turkey to Greek Islands Ferry Guide 2026 page. You'll also find a brief guide for travelers from Turkey in the final section below.

① Overview of the Greek Ferry Network

The heart of the Greek ferry system is the port of Piraeus. Located southwest of Athens, this port is one of Europe's largest passenger ports, handling approximately 18 million passengers annually, and serves as the main gateway to the islands. Regular services depart from Piraeus towards the Cyclades, Dodecanese, North Aegean, and Crete. In practice, this is also where the culture of "island hopping" — sequentially visiting multiple islands by ferry — began: staying on one island for a day and moving to a neighboring one the next is a common way to travel in Greece.

Athens actually has three ports, and knowing which one you're departing from is crucial. Services to the same island might depart from two different ports; going to the wrong port will disrupt your schedule:

• Piraeus: The largest central hub, offering the most routes. Services are available to almost every island group. The Piraeus Port Authority (OLP) operates the port; as there are multiple gates across a large area, it's important to check the departure gate on your ticket.
• Rafina: An alternative port east of Athens, offering shorter distances to some Cycladic islands (especially Andros, Tinos, Mykonos) compared to Piraeus. Operators like Golden Star Ferries have strong services departing from Rafina.
• Lavrio (Lavrion): The southernmost, smaller port; serves a more limited number of Cycladic and North Aegean routes.

Greek ferries come in two main types: high-speed catamarans (e.g., SeaJet type) and traditional conventional vessels. The time and price difference between the two can be up to double on some routes — we've dedicated a separate section to this later. The backbone of the network is formed by several major operators; some, like Blue Star Ferries, operate year-round, while others, like SeaJets, operate only during the summer season.

Methodology note: The duration and price ranges in this guide have been cross-referenced with authoritative industry sources (Ferryhopper, Direct Ferries). The figures provided are starting prices for a single economy/deck passenger; average prices are generally 1.5–3 times higher and increase with vehicles/cabins. Therefore, throughout this article, we always use the phrase "starting from €X".

② Island Groups and Main Routes

The Greek islands are divided into geographical groups. Below, you'll find the main domestic routes, duration ranges, and operators for each group. All prices are "starting prices" for a single economy/deck passenger — they vary significantly depending on the season, operator, and vessel type.

Cyclades — Santorini, Mykonos, Naxos, Paros

The Cyclades are Greece's most popular holiday archipelago and attract the majority of ferry traffic. They are served from Piraeus and Rafina, with very frequent inter-island connections. A classic Cycladic island hopping route generally starts from Piraeus, heading to Santorini via Mykonos or Naxos — as connections between these three are repeated multiple times a day throughout the summer.

• Piraeus → Santorini: High-speed catamaran (SeaJets) 5 hours – 6 hours 10 minutes; conventional (Blue Star) 6 hours 10 minutes – 9 hours 10 minutes; Fast Ferries ~10–11.5 hours. Conventional starting from €46, high-speed catamaran starting from €90. Operators: Blue Star, SeaJets, Fast Ferries.
• Piraeus → Mykonos: 2 hours 40 minutes – 5 hours 50 minutes (from fastest to those with stops). Passenger prices starting from €44; vehicle passage is more expensive. SeaJets, Golden Star, Fast Ferries.
• Naxos → Santorini: 1 hour 5 minutes – 2 hours 45 minutes. Starting from €31.50, with frequent services throughout the summer. This is one of the most economical short connections to Santorini within the Cyclades. Blue Star, Fast Ferries, SeaJets.
• Mykonos → Santorini: 1 hour 50 minutes (fastest) – 3 hours 15 minutes, average ~2.5 hours. As only high-speed catamarans operate on this route, the base price is higher: starting from €82.50. SeaJets, Golden Star.

As you can see, the base price for the Mykonos–Santorini route is approximately two and a half times that of Naxos–Santorini; this difference alone explains why budget travelers often choose Naxos as an intermediate stop. All these prices vary by season; the current schedule should be confirmed through the operator or Ferryhopper.

Dodecanese — Rhodes, Kos, Symi, Patmos

The archipelago closest to Turkey's southwestern coast. Rhodes and Kos are two strong regional hubs; inter-island connections are very frequent, and prices are significantly lower compared to the Cyclades. There isn't a single operator dominating this region — operators like Blue Star (conventional), Dodekanisos Seaways (catamaran/hydrofoil, regional leader), SAOS, and ANEK Kalymnoy operate in conjunction.

• Kos → Rhodes: Blue Star ~5 hours 50 minutes, SAOS 7 hours 20 minutes, Dodekanisos 8 hours 5 minutes (hydrofoil options may be faster). Starting from €14.50. Blue Star, Dodekanisos Seaways, SAOS. A daily route with multiple services.
• Rhodes → Symi: 45 minutes (Dodekanisos fast) – 1 hour 20 minutes (conventional). Starting from €7, up to 3 services per day. Ideal for a day trip to Symi. Dodekanisos Seaways and local ferries.
• Kos → Patmos: ~1 hour 30 minutes, starting from €9.50, daily. Dodekanisos Seaways, Blue Star.
• Kos → Kalymnos: ~30 minutes, starting from €5 — one of the shortest and cheapest hops in the region. ANEK, Dodekanisos, Blue Star, SAOS.
• Rhodes → Santorini: A rare confirmed direct connection from the Dodecanese to the Cyclades: Blue Star ~11 hours, starting from €20.50, 3-7 services per week. This is the most reliable direct route to Santorini among the gateway islands.
• Rhodes → Heraklion (Crete): Blue Star ~10 hours 15 minutes, starting from €21, 2-5 services per week. One of the rare routes directly connecting the two ends of the Aegean.

Important limitation: There are no direct services from small islands like Symi and Tilos to any Cycladic island; you need to disembark at Rhodes or Kos and transfer. Similarly, the direct route from Symi to Piraeus exceeds 13 hours (starting from €63), which is why most passengers heading to Athens travel via Rhodes or Kos.

North/East Aegean — Lesvos, Chios, Samos, Lemnos

In these islands, which run parallel to the Turkish coast, Greek domestic routes are largely a Blue Star monopoly (it is the sole operator, especially in Lesvos). There are long direct routes to Piraeus and inter-island connections; the only bridge to the Cyclades is via Mykonos.

• Piraeus → Chios: 6 hours 55 minutes – 8 hours 15 minutes (up to ~14 hours on services with stops). Starting from €40. Blue Star (ANEK Superfast joint service), SAOS Ferries.
• Piraeus → Lesvos: 9 hours 50 minutes – 12 hours 15 minutes. Starting from €48–52. Blue Star is the sole operator; generally a long overnight route.
• Lesvos ↔ Chios: ~2 hours 15 minutes, starting from €14, 6-7 services per week. This is the most practical bridge between these two large North Aegean islands. Blue Star.
• Samos → Mykonos: ~3.5–4.5 hours, starting from €18.50. The most practical bridge from the North Aegean to the Cycladic network — disembarking at Mykonos offers very frequent onward connections towards Santorini, Naxos, and Paros. Blue Star, SeaJets.
• Chios → Mykonos: ~5 hours 45 minutes, starting from €17. The only bridge to the Cyclades via Chios; operates on limited days.

There are no direct services from the North Aegean to Santorini — access to the Cyclades from Samos, Chios, and Lesvos is only via the Mykonos bridge, with a transfer to Santorini from there. Therefore, for those targeting Santorini from the North Aegean, an overnight stay in Mykonos is generally advisable.

Saronic — Aegina and surroundings

These small Gulf islands, right next to Athens, offer the quickest escape from the mainland and are the most suitable group for day trips.

• Piraeus → Aegina: 30 minutes (high-speed) – ~1 hour 10 minutes (conventional). Starting from €9.50, with over 40 services per day in summer. This frequency makes the Saronic islands ideal for morning-departure, evening-return plans. Aegina Ferries, Hellenic Seaways, Saronic Ferries, and other local operators.

Crete — Heraklion and the Aegean bridge

Greece's largest island, Crete, is a hub in itself and has strong connections with Piraeus. Both overnight conventional and daytime high-speed options are available.

• Piraeus → Heraklion: 7 hours 50 minutes – ~12 hours (generally overnight conventional + daytime high-speed). Passenger prices starting from €33; vehicle and motorcycle passage incurs additional fees. Minoan Lines, Blue Star, ANEK, Hellenic Seaways, SeaJets — this route has one of the busiest lists of operators.

Crete is also directly connected to Rhodes (Dodecanese) (as mentioned above); this is a valuable bridge for long-route planners looking to link the archipelagos.

③ Main Operators Table

A few major operators dominate the Greek domestic network. Knowing which operator serves which region makes it easier to choose the right vessel and purchase tickets from the correct official website.

In addition, regional operators such as SAOS Ferries (North Aegean + Dodecanese economical conventional, low frequency-low price), ANEK/Superfast (Crete, Dodecanese joint/code-share services), and Aegean Speed Lines (Cyclades high-speed, Piraeus–Serifos–Sifnos–Milos) also provide services. For correct booking, pay attention to operator domains — commonly confused ones: SeaJets .com, Golden Star .com, Fast Ferries .com.gr, Dodekanisos Seaways 12ne.gr.

④ High-Speed Catamaran or Conventional Ferry?

You'll generally find two options on the same route, and the choice depends on your budget and schedule:

• High-speed catamaran (SeaJets, Golden Star high-speed): Significantly shortens travel time. For example, while a conventional ferry on Piraeus–Santorini takes 6–9 hours, a high-speed catamaran arrives in 5–6 hours. However, the price jump is substantial: conventional ferries on Piraeus–Santorini start from €46, while high-speed catamarans start from €90. On some routes, like Mykonos–Santorini, only high-speed catamarans operate, so the base price is naturally higher (starting from €82.50). High-speed catamarans generally operate only during the summer season (April–November).
• Conventional vessel (Blue Star, Fast Ferries): Slower but significantly cheaper and more stable. Less affected by choppy weather compared to high-speed catamarans (conventional ferries may continue operating even if catamarans are canceled); offers cabin options on long overnight services. Travel on the open deck is the most economical ticket type.

Practical rule: On routes like Santorini, Mykonos–Santorini, and Crete, the vessel type can nearly double the price, so when searching for tickets, check the duration/price balance rather than just the "fastest" option. All prices vary by season, and the current schedule should be confirmed through the operator or Ferryhopper.

⑤ Seasonality — Summer and Winter Differences

Greek ferry schedules are highly sensitive to the season. Most Cycladic routes are busy between April–November; in winter, service frequency drops significantly, or some routes close entirely. This variability in service numbers makes island hopping plans fragile for winter and shoulder seasons.

• Summer (high season): Popular routes have many services per day. A striking example is Naxos–Santorini: it can increase to up to 8 services per day in summer, but the same connection might drop to just 1 per week in winter. Mykonos–Santorini and Naxos–Mykonos also reach 6–8 services per day in summer.
• Winter (low season): The same routes might drop to a few services per week, with some small island connections falling to 1 per week. Most high-speed catamaran operators (like SeaJets) do not operate at all in winter; generally, only year-round conventional operators like Blue Star remain.

Therefore, if you're planning to travel after September or in early spring, be sure to check inter-island connections in advance — the Aegina ferry that departs every 30 minutes in summer, or the Naxos–Santorini vessel that departs 8 times a day, might not even run once a day in winter. During high season, the opposite risk applies: popular routes fill up quickly, so early booking is recommended for July–August.

⑥ How to Buy Tickets?

You can purchase Greek domestic ferry tickets through several channels:

1. Meta-search platforms: Ferryhopper compares over 220 operators in a single interface; it clearly shows the duration range, starting price, operator list, and daily service count for each route. It supports a Turkish interface.
2. Direct Ferries (TR): Another comparison platform with a full Turkish version, clearly showing the price range (lowest–highest).
3. Official operator websites: Correct domains for direct booking — Blue Star (bluestarferries.com), SeaJets (seajets.com), Dodekanisos Seaways (12ne.gr), Golden Star (goldenstarferries.com), Fast Ferries (fastferries.com.gr), Minoan (minoan.gr), Hellenic Seaways (hellenicseaways.gr). Some operators offer early booking discounts (e.g., Dodekanisos Seaways up to 50% off for bookings 7+ days in advance).

Comparison platforms are the most practical starting point for most travelers, as they display all operators side-by-side in a single search; they are powered by Greece's official reservation infrastructure (distribution systems that also feed the operators' own systems), thus ensuring high schedule reliability.

Important warning — potential strike days: 24-hour strikes declared by Greek seafarers' unions can completely halt services. These strikes are generally announced in advance and may coincide with specific symbolic dates (e.g., Labor Day on May 1st). Before departing, checking the current disruption and strike status on Ferryhopper's disruption page or from Greek travel news sources is critical to avoid inconvenience. In case of strikes, delays, or weather-related cancellations, planning a flexible day is always wise when island hopping.

Plan Your Island Hopping Route with a Hub Strategy

The secret to efficient travel within the Greek domestic network is choosing the right hub. Each archipelago has one or two strong distribution centers, and building your route around these centers saves both time and money:

• Hub for the Cyclades: Piraeus (or Mykonos/Naxos): Disembarking at Mykonos or Naxos from Piraeus, and then reaching Santorini with short connections (6-8 services daily) is the most practical arrangement. An intermediate stop at Naxos is also a way to avoid the high base price of the direct Mykonos-Santorini route (starting from €82.50).
• Hub for the Dodecanese: Rhodes and Kos: There are many daily services between these two islands; you can distribute to smaller islands like Symi, Tilos, Patmos, Kalymnos, Nisyros from them. Since there are no direct services from Symi and Tilos to the Cyclades, those wishing to go to the Cyclades must first disembark at Rhodes or Kos.
• Bridge for the North Aegean: Mykonos: The only passage from Samos, Chios, and Lesvos to the Cyclades is via Mykonos; the Samos-Mykonos route (starting from €18.50) is the most practical option for this bridge.
• Saronic day trips: Saronic islands like Aegina are ideal for morning-departure, evening-return trips while staying based in Athens; you can keep your accommodation on the mainland.

General principle: long direct routes (e.g., Symi-Piraeus 13+ hours, Lesvos-Piraeus ~10 hours) can be tiring; often, staying overnight on a hub island and traveling in segments is both more comfortable and more reliable in terms of schedule.

⑦ Brief Guide for Those Connecting from Turkey

If you wish to travel from Turkey's Aegean coast to a Greek island and then connect to the Greek domestic network, the logic is the same: first, you travel from a Turkish port to a "gateway island" (such as Kos, Rhodes, Samos, Chios, Lesvos, Symi, Tilos), and from there, you continue with the domestic services described in this guide. The most efficient gateway islands and onward connections — for example, direct from Rhodes to Santorini, or via the Mykonos bridge from Samos to the Cyclades — are detailed step-by-step in separate guides:

• General starting point: Turkey to Greek Islands Ferry Guide 2026
• To Santorini via Rhodes transfer: Turkey to Santorini Ferry (via Rhodes Transfer) — Rhodes has the most reliable direct route to Santorini among the gateway islands.
• Santorini departing from Bodrum: How to Get to Santorini by Ferry from Bodrum
• Izmir–Athens route: How to Get to Athens by Ferry from Izmir
• Kuşadası–Samos to Mykonos: Kuşadası–Samos to Mykonos Ferry — Samos is the most practical bridge from the North Aegean to the Cycladic network.

For popular routes departing from Turkey: Bodrum–Kos, Marmaris–Rhodes, Çeşme–Chios. For arrival destinations, you can check our Santorini and Mykonos pages.

⑧ Visa Warning — Don't Skip This

Schengen rule: The "visa at the door" (Visa Express) application valid for Turkish citizens is ONLY valid for the island of entry. With this visa, you cannot travel to another Greek island, the Greek mainland (Athens, Thessaloniki), or another Schengen country. This means entering Kos with a visa at the door and then traveling to Santorini or Piraeus from there is forbidden. For free movement within the Greek domestic network, a full Schengen visa is required. Furthermore, a visa at the door is not issued under any circumstances for Cycladic/southern islands like Santorini, Mykonos, Crete, and Paros. For details: Greek Islands Visa at the Door Guide 2026.

In short: To legally use the vast majority of inter-island and mainland–island routes in this guide, you must possess a full Schengen visa. A visa at the door only permits a stay of 7 days on a single gateway island.

The duration and price information in this guide are cross-referenced starting prices as of June 5, 2026. Always confirm the current schedule through the operator or Ferryhopper throughout the 2026 summer season.
