Greek Islands Sailing Guide

Master Mariner Directory · Mediterranean Guides · 2024

Greece offers more sailing variety per square mile of chart than almost anywhere else on the planet. From the sheltered Ionian channel — where the islands of Lefkas, Ithaca, Kefalonia, and Zakynthos sit within a day's sail of each other — to the exposed Cyclades where the meltemi can pin you in harbor for three days, the Greek islands present every level of challenge. The question for any cruiser planning a Greek passage is not whether to go, but where to go first, and what to expect when the summer wind arrives.

The Ionian Islands: The Cruiser's Motorway

The Ionian chain — running south from Corfu past Lefkada, Ithaca, Kefalonia, and Zakynthos — is where most new Mediterranean cruisers begin their Greek sailing education, and with good reason. The islands are close together, the anchorages are numerous and well-charted, the meltemi barely reaches this far west (the dominant pattern here is a lighter northwesterly called the maestro), and the Lefkada Canal allows passage south without rounding the island's exposed northern headland. Lefkas Marina at the southern entrance of the canal is the primary charter hub: a modern, well-equipped facility with fuel, water, provisioning steps walking distance from the basin, and a concentration of charter companies that keeps maintenance standards high.

Sailing south from Lefkas, Ithaca offers the legendary harbor of Vathy — a long, narrow inlet that provides complete shelter in all conditions — and a handful of quieter bays on the island's southern coast. Kefalonia is larger and more varied: Fiskardo in the north is the tourist jewel (crowded in summer, with good tavernas and a deep protected harbor), while the anchorages on the island's west coast see far fewer boats. Zakynthos at the chain's southern end has the famous Navagio (Shipwreck Beach) — accessible by dinghy if you anchor off the adjacent headland in calm conditions — and serves as the jumping-off point for boats heading east to the Peloponnese or south around the Peloponnese to the Saronic Gulf.

The Saronic Gulf: Athens as a Base

Athens is an improbable sailing base — a vast, congested city — but the marinas at Alimos and Flisvos in the southern suburbs put you within three hours of some of the most convenient island sailing in Greece. The Saronic Gulf, protected from the north by Attica and from the south by the Peloponnese, presents a much more benign wind environment than the Cyclades: the prevailing summer breeze is the light northerly called the livas, and the occasional southerly brings warm air off the Peloponnese without developing the strength of open-water weather.

Aegina, closest to Athens at roughly 17 miles, has two harbors — the town harbor (tourist, lively, good provisioning) and the quieter anchorage at Perdika on the island's southern tip. Hydra, farther south, is one of the Mediterranean's most distinctive harbor towns: no motor vehicles, a port enclosed by stone houses rising steeply above the quay, and a ban on anchoring that means you take a stern-to buoy or leave. Spetses, at the Saronic's southern end, has a well-sheltered harbor at the Old Port and good anchorages on the island's southern coast. The Saronic circuit from Athens — Aegina, Hydra, Spetses, and back via Porto Heli on the mainland — is a classic one-week passage that has converted more landlubbers to sailing than any other route in Greece.

The Cyclades: Meltemi Wind Reality

The Cyclades are beautiful, demanding, and frequently misrepresented by charter companies whose photography happens in May and September. From June through August, the meltemi — a northerly to northwesterly established wind that blows from the Aegean high-pressure system — arrives in the Cyclades with a consistency and force that rewards experienced crews and humbles novices. Force 5 is routine. Force 6 is common. Force 7 passages in the open channels between islands are entirely normal and should be treated as such: reef early, plan your passages for morning before the wind builds, and never commit to a crossing without a realistic fallback anchorage.

Within this context, the Cyclades are magnificent. Mykonos has the harbor facilities to handle significant boat traffic and a cosmopolitan scene that either appeals or doesn't. Paros — specifically the town of Naoussa in the north — is arguably the most balanced Cycladic stop: good marina infrastructure, excellent tavernas, beautiful water, and a population that extends well beyond tourism. Santorini is the visual icon, but the caldera anchorage (the collapsed volcanic crater in the island's center) is rolly, crowded, and subject to sudden gusts off the crater walls; most experienced sailors anchor for a night, take the water taxi to town, and move on. The quieter southern Cyclades — Folegandros, Sifnos, Milos — reward the effort to get there with fewer boats and more authentic Greek island character.

The Dodecanese: Turkish-Coast Day-Hops

The Dodecanese stretch along the Turkish coast from Patmos in the north to Rhodes in the south, close enough to the Turkish mainland that day-passages between the two countries are routine from the right ports. Rhodes is the major charter base: a large commercial harbor with full marina facilities, an impeccably preserved medieval city within walking distance, and easy access to the Turkish coast via Marmaris (see the Turkey guide). Kos has a good harbor and the airport that many charter clients use. Patmos, at the northern end of the chain, is quiet, steeply beautiful, and less visited than the southern islands — an anchor stop rather than a provisioning base.

The Turkish-coast day-hops are a significant draw for Dodecanese cruisers: from Rhodes, Marmaris is roughly 18 miles. From Kos, Bodrum is 6 miles. These passages require checking out of Greece formally (port police, customs, and harbormaster stamps) and checking into Turkey on arrival, which for non-EU boats involves the transit log process described below. The crossings themselves are short and straightforward; the paperwork takes longer than the sailing.

Flotilla Sailing and Charter Logistics

Greece is the world's most developed flotilla sailing market. A flotilla typically involves 8–12 boats sailing in loose convoy with a lead boat crewed by a professional skipper and a hostess, plus a motorboat that assists with mechanical problems and meets flotillas at each night's harbor. For first-time Mediterranean sailors or those unfamiliar with Med mooring (stern-to, anchor forward), flotillas offer meaningful support without removing the experience of sailing your own boat. The Ionian is the most popular flotilla ground; the Saronic and the Dodecanese also have established flotilla routes.

Bareboat charter in Greece requires demonstrating competence to the charter company — typically an RYA Day Skipper or equivalent certificate, a logbook showing offshore miles, and a second qualified crew member for boats over a certain size. Lefkas Marina concentrates the highest density of charter companies in Greece; Athens marinas (Alimos, Flisvos) have significant fleets; Rhodes serves the Dodecanese.

Customs Procedures for Non-EU Boats

EU-flagged boats with EU-national crew have simplified entry into Greece. Non-EU flagged boats — American, British, Australian, Canadian — require a DEKPA (Diploma Ektelonismou Plion Peregou Archaegos, the transit log) obtained from the first port of entry's customs authority. The DEKPA is valid for six months and allows you to cruise Greek waters; extensions are available. It must be presented at each port of call on request and stamped at ports with customs presence. Losing it is a serious inconvenience; carry a photocopy separately from the original.

The port police (Limenarchion) and customs (Telonio) are the two bureaucratic touchpoints. In major harbors, these are separate offices; in smaller islands, the port police handle both functions. Non-EU boats entering Greece for the first time must fly the yellow Q flag until cleared. The process in established ports is routine and usually completed within an hour.

Water Taxis, Ferries, and Harbor Logistics

Greek island ferries are fast, frequent, and run on routes that sometimes cross the path of sailing vessels at inconvenient times. In the Cyclades especially, the high-speed ferries between Athens (Piraeus) and the islands travel at 30+ knots and produce a significant wake — give them wide berth and cross their track only when you are certain of the timing. Water taxis operate in many harbors, connecting boats anchored off to the quay; in Hydra, where motor vehicles are banned, the water taxi is the primary way to get provisions to the boat.

Med mooring — anchor forward, stern-to the quay — is the default harbor configuration throughout Greece. Practice it before you arrive; arriving in a crowded harbor in a fresh meltemi with no stern-to experience is not the moment to learn. Marinas in major ports have laid moorings (pick up the pendant rather than setting your own anchor), but anchorages and village quays require your own anchor and the confidence to set it in a crowd.

Frequently Asked Questions

What makes the Ionian Islands the most suitable starting point for new Mediterranean cruisers? The Ionian chain from Corfu south through Lefkada, Ithaca, Kefalonia, and Zakynthos offers close-together islands, numerous well-charted anchorages, and a lighter northwesterly wind called the maestro rather than the powerful meltemi that dominates the Cyclades in summer. Lefkas Marina at the southern entrance of the Lefkada Canal is the primary charter hub with modern facilities, fuel, water, and provisioning within walking distance. The Lefkada Canal itself allows southbound passage without rounding the island's exposed northern headland. This combination of short passages, reliable anchorages, and manageable wind conditions makes the Ionian the standard recommendation for first-time Mediterranean sailors.

What is the meltemi and how should sailors plan passages through the Cyclades in summer? The meltemi is a northerly to northwesterly established wind blowing from the Aegean high-pressure system through the Cyclades from June through August. Force 5 is routine; Force 6 is common; Force 7 passages between islands are entirely normal and should be treated accordingly. Charter company photography happens in May and September, creating a misrepresentation of typical summer conditions. The planning rules are reef early, plan passages for morning before the wind builds, and never commit to a crossing without a realistic fallback anchorage. Within these parameters the Cyclades are magnificent: Paros is described as the most balanced stop with good marina infrastructure and excellent tavernas, while quieter southern islands including Folegandros, Sifnos, and Milos reward the effort to reach them.

What documents do non-EU boats need to cruise Greek waters and where are they obtained? Non-EU flagged boats — including American, British, Australian, and Canadian vessels — require a DEKPA (Diploma Ektelonismou Plion Peregou Archaegos, the transit log) obtained from the first port of entry's customs authority. The DEKPA is valid for six months, allows cruising in Greek waters, and must be presented at each port of call on request and stamped at ports with customs presence. Extensions are available. EU-flagged boats with EU-national crew have simplified entry. Non-EU boats entering Greece for the first time must fly the yellow Q flag until cleared; the process in established ports typically completes within an hour through port police and customs offices.

What is the Saronic Gulf's character and what does the classic one-week circuit involve? The Saronic Gulf, protected by Attica to the north and the Peloponnese to the south, has a much more benign wind environment than the Cyclades — the prevailing summer breeze is a light northerly called the livas, without the meltemi's force. The classic one-week Saronic circuit from Athens — Aegina, Hydra, Spetses, and back via Porto Heli — is described as having converted more landlubbers to sailing than any other route in Greece. Hydra is particularly distinctive: no motor vehicles, stone houses rising steeply above the quay, and a ban on anchoring that requires taking a stern-to buoy. Alimos and Flisvos marinas in Athens's southern suburbs serve as the base.

How does flotilla sailing work in Greece and who is it designed for? Greece is the world's most developed flotilla sailing market. A flotilla typically involves 8 to 12 boats sailing in loose convoy with a lead boat crewed by a professional skipper and a hostess, plus a motorboat that assists with mechanical problems and meets flotillas at each harbor. The system offers meaningful support for first-time Mediterranean sailors or those unfamiliar with Med mooring — stern-to with anchor forward — without removing the experience of sailing one's own boat. The Ionian is the most popular flotilla ground; the Saronic and Dodecanese also have established flotilla routes. Med mooring should be practiced before arrival: arriving in a crowded harbor in a fresh meltemi without stern-to experience is not the moment to learn.

What makes the Dodecanese attractive for sailing and how do Turkish coast day-hops work from there? The Dodecanese stretch along the Turkish coast from Patmos to Rhodes, close enough to the Turkish mainland that day-passages between countries are routine: from Rhodes, Marmaris is roughly 18 miles; from Kos, Bodrum is 6 miles. Rhodes is the major charter base with full marina facilities and an impeccably preserved medieval city within walking distance. The crossings themselves are short and straightforward; formal checking out of Greece through port police, customs, and harbormaster and formal checking into Turkey on arrival takes longer than the actual sailing. For non-EU boats this involves the transit log process used in Greek waters applied in reverse for Turkish entry.
