Sailing the Ionian Islands — The Complete SeaTV Guide
Greece’s western archipelago — from Corfu’s Venetian harbours in the north to Zakynthos’s blue caves in the south. The most forgiving Greek charter waters, with reliable winds, short hops between islands, and one of the densest concentrations of good anchorages in the Mediterranean.
The Ionian Islands lie off Greece’s western coast, in a chain running south-to-north from Zakynthos through Kefalonia, Ithaca, the inner Ionian (Meganisi, Kastos), Lefkada, Paxoi, and ending at Corfu in the north — closer there to the Albanian coast than to mainland Greece. Each island has a distinct character: Corfu’s old town carries Renaissance, baroque, and classical architecture; Ithaca holds the legend of Odysseus; Zakynthos has the most photographed beach in Greece; and Kefalonia offers more variety than any other single Ionian island.
For sailors, the Ionian is the most forgiving Greek charter region. The summer wind is a steady moderate NW thermal — strong enough for proper sailing, light enough not to confine the schedule. The Meltemi that dominates the Aegean is largely blocked by the mainland mountains. Distances between islands are short — usually 8–15 NM hops — and there are good anchorages and harbours every few miles. It is the reason most charters in Greece start either here or in the Aegean, and the reason this region rewards both first-time charter crews and seasoned sailors alike.
⚠ Reality check: “Forgiving” doesn’t mean “easy” — the Ionian still demands proper anchoring discipline (Posidonia seagrass is widespread), respect for afternoon thermal winds (15–25 knots is normal), and awareness of the few exposed harbours that turn uncomfortable on a wind shift. Each island page on this site flags the specifics. Read them before committing to a route.

Why Sail the Ionian?
Reliable, predictable wind. The summer NW thermal builds through the morning, peaks 14:00–17:00 at 15–25 knots in the open channels, and drops in the evening. You can plan a charter day around it — morning provisioning, midday sail, evening berth.
Short distances. Most island-to-island hops are 8–15 NM. A 6-knot average gets you to lunch by 13:00 and dinner by 19:00 on most legs. No epic overnight passages required.
Density of choice. From Lefkada south to Ithaca alone, there are 25+ usable anchorages and harbours within a 20 NM radius. You can change plans on the day based on wind, mood, or how the crew is doing.
Real Greek towns. Vathy on Ithaca, Fiskardo on Kefalonia, Kioni, Lakka, Gaios — these are working Greek harbours, not artificial marina developments. Walk-ashore dinner, locally-caught fish, evening at a waterfront taverna.
Wind & Weather Pattern
The summer pattern
From late May through September, the Ionian is dominated by the NW thermal (Maistros). Mornings are calm or light, the wind builds through midday, peaks mid-afternoon, and drops after sunset. Most days are in the 10–20 knot range — comfortable for full sailing without reefs. A few days each summer reach 25–30 knots; reefs and a careful route choice handle these.
Local exceptions
→ Vasiliki, southern Lefkada: Famous “windsurfer’s bay” — the wind funnels through the gap between Lefkada and Kefalonia, sometimes 20–30 kn when other places are calm.
→ Pera Pigadhi, SE Ithaca: Late-afternoon katabatic gusts off the Ithaca hills — 20–30 kn possible.
→ South Zakynthos / Lagana Bay: More exposed than the inner-Ionian harbours; a southerly forecast changes everything here.
→ Corfu Channel: Open to N and S; check forecast before crossing to Albania or Italy.
Sea state
Mostly settled in the protected inner channels (between Lefkada–Meganisi–Ithaca–Kefalonia). The west coasts of Lefkada, Kefalonia, and Zakynthos see open Ionian Sea swell — no overnight anchorages here, only daytime visits.
⚓ Main Charter Bases
Lefkas Marina (D-Marin) — The largest charter base in the southern Ionian. Best position for one-week trips covering Meganisi, Ithaca, Kefalonia.
Marina Gouvia, Corfu — Northern base. Best for trips covering Corfu, Paxoi, Albania border, and southbound to Lefkada.
Preveza Marina (mainland) — Smaller, cheaper, less polished — but in a useful position halfway between Corfu and Lefkada. Good for budget-conscious crews.
The Ionian Atlas — by Region
Far North · Corfu & Paxoi
Corfu & Paxoi
Corfu — the largest Ionian island, with a Venetian old town, fortress, and the most Italian-feeling architecture in Greece. Paxoi — much smaller, two villages around two charming harbours, an easy 8 NM south of Corfu.
→ Marina Gouvia, Corfu — main charter base
→ Sailing the East Coast of Corfu
→ Gaios, Paxoi — fjord-like village harbour
Central · Lefkada (Connected to Mainland)
Lefkada
The geographic centre of Ionian charter sailing — connected to the mainland by a swing bridge, separated from Meganisi by a narrow channel, and surrounded by some of the best protected anchorages in Greece.
→ Lefkas Marina (D-Marin) — main charter base
→ Nidri — busy yacht hub
→ Vasiliki — windsurfer’s bay

Inner Ionian · Meganisi & Kastos
Inner Ionian Islands
A cluster of small protected islands east of Lefkada — short hops, calm channels, and some of the most relaxed anchorages on the route.
→ Meganisi Island — Vathy, Abelaki, Spartochori
→ Kastos Island — smallest inhabited island, no cars
South-Central · Kefalonia
Kefalonia
The largest Ionian island and the most varied — west-coast cliffs and Myrtos Beach, east-coast harbours, the photogenic Fiskardo, Melissani Cave, and the practical service hub at Sami.

SeaTV’s own full-length route — a real two-week trip log covering the full archipelago. The best comprehensive view of what an extended Ionian charter looks like.
Pro Tips for Sailing the Ionian
Sail mornings, dock afternoons. The thermal builds 11:00–14:00 and peaks late afternoon. If you want to dock easily and avoid wrestling with a 20-knot crosswind on the quay, plan to arrive between 13:00 and 15:00. Evening starts make for difficult berthings.
Posidonia is the constant. Most Ionian bottoms have at least patches of Posidonia seagrass. It holds badly. Visually identify a sand patch before dropping — and don’t be embarrassed to re-set if the first drop is on weed.
Long line ashore is the local standard. Many Ionian anchorages reward an anchor + line ashore over a free-swing. Saves space, stops the boat sailing on the anchor, gives certainty in afternoon gusts. Stock 50 m of floating line and learn the technique.
Town quays fill early in season. Vathy, Fiskardo, Kioni, Lakka — all popular harbours fill by 14:00 in July–August. Plan arrivals early or have an anchor plan ready.
Skip the west coasts. West coasts of Lefkada, Kefalonia, and Zakynthos are exposed to open Ionian Sea swell — daytime visits only, never overnight. Plan circuits that keep you on the protected eastern sides.
Provision in the right places. Lefkas, Sami, Vathy, Gouvia have proper supermarkets. Smaller stops (Kioni, Kastos, Spartochori) are basics-only — top up before you push into them.
What to See — Beyond the Sailing
Corfu Old Town: UNESCO-listed Venetian, baroque, and classical architecture. The 19th-century Liston promenade with arcades and cafes. Don’t miss the Old Fortress.
Melissani Cave, Kefalonia: An underground lake under a partially-collapsed cave roof — when the sun is high, the water glows electric blue. Boat tours from Sami.
Antisamos Bay, Kefalonia: White-pebble beach in a green amphitheatre — used as a film location for Captain Corelli’s Mandolin.
Shipwreck Beach (Navagio), Zakynthos: The most photographed beach in Greece — vertical limestone cliffs, white sand, a rusting ship. View by sea (no anchorage at the beach itself).
Stavros & the Cave of Nymphs, Ithaca: Archaeological sites linked to Odysseus, accessible from Polis Bay or Vathy.
Fiskardo Venetian houses, Kefalonia: The 1953 earthquake spared this single village — pastel-coloured Venetian-era buildings line the harbour.
