Sailing the Greek Islands

Destination Guide · Mediterranean

Greece sells itself on the postcard — blue-domed churches above white cubic houses, improbably clear water, ruins above the treeline. The postcards are accurate, but they do not tell you the difference between the Aegean and the Ionian, and that difference is the most important thing a cruising sailor needs to understand before booking a charter flight to Athens.

These are not two halves of the same experience. The Aegean is dramatic, wind-scoured, and demanding in summer. The Ionian is calm, green, and manageable for sailors who want to focus on the scenery rather than the wind angle. Choose wrong for your skill level and the trip will be remembered for the wrong reasons.

The Aegean vs. the Ionian

The Aegean Sea lies east of mainland Greece, bounded by Turkey to the east and Crete to the south. It is an open, island-scattered body of water without the geographic shelter that defines the Ionian. The Cyclades — Mykonos, Santorini, Paros, Naxos, Ios — sit in its center, exposed to whatever is coming from the north. The Dodecanese chain, from Rhodes north toward Samos, runs along the Turkish coast in the eastern Aegean.

The Ionian lies west of the Greek mainland, sheltered by the mass of the peninsula to the east. Its islands — Corfu, Paxos, Lefkada, Meganisi, Ithaca, Kefalonia, Zakynthos — form a north-to-south chain through relatively protected water. The landscape is greener, wetter, and more Mediterranean in the Italian sense than the bare limestone geology of the Cyclades. The sailing is gentler, the anchorages more sheltered, and the logistical infrastructure for bareboat charterers considerably more developed.

Neither is superior. They are suited to different sailors and different intentions.

The Meltemi

The Meltemi is the defining weather feature of the Aegean summer, and understanding it is non-negotiable before you sail there in July or August. It is a dry, warm, north-to-northwest wind driven by a semi-permanent pressure difference between a high over the Balkans and a thermal low over Turkey. It builds through the morning, peaks in the early afternoon at 20 to 35 knots, and drops after sunset. In strong years it blows 40 knots sustained for days at a stretch.

The Meltemi is consistent enough to be predictable in its pattern — north-northwest direction, daily build-and-drop cycle — but violent enough in peak expression to make some passages genuinely difficult. Sailing south from Mykonos to Santorini in a 35-knot Meltemi on a beam reach is fast and exhilarating and wet. The return trip, dead into it, is slow and exhausting and wet in a different way.

Certain anchorages that appear on the chart as perfectly positioned become untenable in a Meltemi because they face north or northwest. Others — south-facing coves on the southern sides of islands, deep bays open only to the south — become the most pleasant anchorages in the Aegean precisely because the wind sweeps overhead. Learning to read Aegean charts with Meltemi exposure in mind is the skill that separates an experienced Aegean sailor from a tourist on a boat.

The Meltemi gives you free miles south and makes you pay for every mile north. Plan your week accordingly.

The Ionian Circuit

The classic bareboat week in the Ionian runs the chain from Corfu south to Zakynthos, usually starting and ending at Lefkada — where the largest charter base in Greece operates — or Corfu. The full circuit: Corfu → Paxos → Lefkada → Meganisi → Ithaca → Kefalonia → Zakynthos, with variations by wind and time.

Corfu has the largest airport and the most tourist infrastructure, which makes it a practical start but not the most atmospheric. The harbor at Gaios on Paxos — the smaller island 12 miles south of Corfu — is narrow, lined with Venetian buildings, and genuinely charming in the way that has not yet been fully commodified. Anti-Paxos, a 15-minute sail further south, has two small beaches and water so clear that the anchor chain is visible in 20 feet.

Lefkada is connected to the mainland by a causeway and canal — a detail that matters logistically, as it is the easiest island to resupply and the one where major charter companies concentrate their fleets. The lagoon below Nidri is a sailing kindergarten: flat, protected water where beginners can practice without consequences. The island itself is excellent, with the west coast cliffs at Porto Katsiki among the most spectacular scenery in the Ionian.

Meganisi is the small island east of Lefkada that most tourists miss and most cruisers love: three bays, a handful of tavernas, goats on the hillsides, and an anchorage at Vathy that holds well in any summer wind. Ithaca — Homer's Ithaca, Odysseus's home — is narrow and mountainous, with a perfect horseshoe harbor at Vathy that has been a safe anchorage for approximately three thousand years. Kefalonia is the largest island in the Ionian and has the most variety: caves, beaches, a serious town in Argostoli, and the small harbor at Fiscardo in the north that is, in high season, one of the most crowded anchorages in Greece. Zakynthos closes the chain; its loggerhead sea turtle population makes the waters around the south end a marine protected area with restricted anchoring.

The Dodecanese and the Turkish Coast

The eastern Aegean is a different proposition: the Dodecanese islands run south to north from Rhodes near the Turkish coast. Rhodes, Kos, and Symi are the most-visited; the smaller islands — Tilos, Nisyros, Halki — see fewer boats and reward the extra navigation.

The Turkish coast runs within three miles of Kos, within five of Rhodes. Day trips to Marmaris, Bodrum, or the smaller Turkish ports are common and legally straightforward — Greek-Turkish maritime relations at the operational level are calm and pragmatic, whatever the political noise in the capitals. You exit at a Greek port of clearance, enter Turkey at a Turkish port of entry, get your transit log stamped, spend the day, and return the same way. The crossing takes an hour. The ruins at Knidos, accessible only from the sea, are better approached from the Greek side in a small boat than from the Turkish road.

Symi deserves special mention. The harbor at Gialos is one of the most visually striking in Greece — a horseshoe of neoclassical pastel-painted mansions built during the island's prosperous 19th-century sponge-fishing era. The crowds are real in July and August; arrive before 0900 to find a berth in the inner harbor.

Chartering: The Athens Logistics

Alimos Marina, 15 kilometers south of Athens center, is the primary charter hub for the Aegean. Most major charter companies — Sunsail, Moorings, Neilson, Kiriacoulis, and a dozen Greek independents — base boats there. The marina is functional rather than beautiful: a large commercial facility where hundreds of charter boats turn over on Saturdays. Getting there from Athens Airport takes 45 minutes by taxi or metro. Provisions are available but better to hit a supermarket en route.

The flotilla option deserves consideration for less experienced sailors doing the Aegean for the first time. A flotilla is a group of six to twenty charter boats following a lead boat crewed by professionals, with a set itinerary and a rendezvous point each evening. You sail your own boat at your own pace, but you have support within radio range, local knowledge directing the week's route, and the social dimension of a shared experience. The Ionian is the classic flotilla ground; most operators are UK-based.

Bareboat charter requirements in Greece are set by the Hellenic Ministry of Maritime Affairs. In practice: an ASA 104 (Bareboat Cruising) or RYA Day Skipper certification is the minimum required by most charter companies, plus a logbook showing offshore passages. Some companies will require a skipper or co-skipper endorsement for catamarans or for boats above 45 feet. Bring your original certificates; copies are not accepted.

Customs for Non-EU Sailors

Non-EU flagged vessels, or EU-flagged vessels with non-EU nationals aboard, must obtain a DEKPA — the Greek transit log — upon entering Greek waters. The DEKPA is issued at official ports of entry (limani eisodou), which include Rhodes, Corfu, Patras, Piraeus, and Heraklion, among others. It lists the vessel, her crew, and her planned itinerary, and must be presented at each port that checks papers.

The fines for skipping ports of entry or failing to hold a valid DEKPA are real and have increased in recent enforcement cycles. Greek coast guard vessels do board charter boats, particularly in the Dodecanese where the Turkish border proximity sharpens their interest in documentation. The process at a port of entry is straightforward if your papers are in order: passport copies for all crew, vessel documentation, insurance certificate, and the DEKPA application.

Provisioning

Athens and Piraeus have full supermarket options — load the boat before leaving port, because the situation outside Athens is genuinely thin. Most Cyclades islands have a minimarket; the inventory varies from adequate to sparse depending on what the ferry brought that week. Mykonos and Santorini have decent options because tourist volumes demand it, but prices are correspondingly elevated.

The fish market protocol is simple: find the market, go early (before 0800 in most ports), buy what looks alive and smells like the sea, and negotiate pleasantly. Fish from a Greek island market cooked the same day is the best meal you will have on the trip. The taverna culture handles dinner: arrive after 2100, eat slowly, pay less than you expect. The carafe wine (choriatiko, house wine) served in most island tavernas is often local and often good. Refusing it in favor of a bottled import is considered slightly rude.
