There is a stretch of the Ionian where the water turns a shade of blue that has no name. You see it first from the helm — somewhere south of Meganisi, when the afternoon Maistros has flattened to a whisper and the bow is cutting toward Kefalonia. This is the southern Ionian triangle: Lefkada, Kefalonia, and Ithaca. Three islands so close together that on a calm morning you can see all of them at once, yet each one feels like a separate world the moment you step ashore from the tender. This Greece Ionian Islands sailing guide: Lefkada, Kefalonia and Ithaca is written entirely from the water — because that is the only honest perspective from which to understand them.
Reading the Ionian: Weather Windows, Wind Cycles and When to Move
Before we talk about anchorages, you need to understand the rhythm that governs every passage in this corner of Greece. The primary summer wind is the Maistros — a north-westerly sea breeze that builds gently around midday, peaks in the afternoon at Force 3–5, and dies down by sunset. That predictability is your greatest asset as a motor boater. In the Ionian in the height of summer, it is said that you can set your watch to the wind — not a breath before 11am, then a gradually building medium breeze that is ideal for a relaxed afternoon passage, before the wind goes to sleep shortly before dusk.
The practical consequence: depart anchorage by 09:00, cover ground in the glassy morning calm, arrive at your next destination and take your berth or swing at anchor before the Maistros arrives in earnest. In July and August temperatures run 30–35°C, the sea is perfect for swimming, and towns are buzzing. Afternoon winds reach 10–20 knots. This is peak season, so mooring space can be limited in popular ports. Berths at Fiskardo and Kioni go fast — arriving after 15:00 in August is a gamble you will almost certainly lose. The Meltemi wind that affects the Aegean is less severe in the Ionian, but afternoon winds in the channel near Lefkada can be lively in summer. Load Navionics Boating with the dedicated Adriatic & Ionian Sea chart subscription (around €55/year) before departure — the app delivers internationally renowned offline charts complete with port plans, anchorages and safety depth contours, alongside multiple overlays so you’re aware of what is above and below the water.
Lefkada: Threading the Canal and Finding Your Ground
Your approach to Lefkada defines the island before you’ve set foot on it. When approaching from the north, you pass through the Lefkada Canal — a shallow, dredged channel that connects the lagoon to the open sea near Aktion. Pay close attention to the channel markers: depths can be limited, and local knowledge or an up-to-date pilot book is strongly recommended for a first-time approach. From the south, entering from the south, pay attention to the narrow channel entrance leading to the ports, marked by four light buoys.
The canal’s famous floating bridge is not a spectacle — it is a navigational fact you must plan around. The floating bridge at Lefkada is one of the most talked-about features of this marina approach. It opens only at scheduled times throughout the day to allow vessels to pass between the southern and northern sections of the lagoon. If you are arriving from the north or planning to depart northward, you must time your passage carefully to align with the bridge opening schedule. At night, theoretically the bridge will open upon request on VHF Channel 12 if a vessel is waiting, but don’t count on it.
D-Marin Lefkas is the hub of the southern Ionian charter world, and for good reason. The total capacity of the marina is 620 berths for vessels up to 45 metres in length and a draft of 4 metres. Approaching the marina, you will receive guidance through VHF Channel 69, and marina staff will welcome you at berth. The marina lies inside a long, L-shaped wavebreak pontoon that shelters the berths from the east and north; entry is from the south between the wavebreak pontoon and the jetty, with the fuel berth at its end. It is also one of the more expensive marinas in Greece, with daily berthing charges in high season among the highest in the southern Ionian. Book your berth well in advance for July and August — D-Marin fills quickly during peak charter season.
For a quieter base, drop the hook off Nidri on Lefkada’s sheltered eastern coast. Nidri, located on the eastern side of Lefkada island, offers an amazing experience for those looking to explore the stunning Ionian Sea. From here you are minutes by tender from Meganisi, Skorpios (the old Onassis island), and the uninhabited islets of Madouri and Sparti — beaches that no road will ever reach.
The Kefalonia Passage: Fiskardo to Argostoli
The run south from Nidri to Fiskardo is one of the finest short passages in the Ionian — roughly 20 nautical miles in open water, with Kefalonia’s limestone massif building on the horizon. This Greece Ionian Islands sailing guide: Lefkada, Kefalonia and Ithaca considers Fiskardo the gateway drug. Arrive here and you will understand immediately why it is the most-photographed harbour in the southern Ionian.
Fiskardo is by far one of the most popular ports in the Ionian, for yachts, superyachts and tourists staying ashore too. This picturesque village houses beautiful Venetian architecture and is one of the few places in the area that remained largely standing following the major 1953 earthquake. Approach coordinates are 38°27’31″N / 020°34’58″E. The lighthouse on the north side of the entrance is easily identified and will guide you to the bay. Do not be seduced by the large space on the ferry quay: moor stern-to on the quay if you are lucky enough to find space. The harbourmaster will keep the ferry quay and tripper boat quay free until late afternoon — you will soon be ushered away if you take that space.
The smarter move is the north shore anchorage. Along the north shore of the harbour there is a good anchorage for 10–12 yachts in depths of 10–12 metres, taking lines ashore to stainless steel rings set into the rocks. Holding is only moderate in sand and some weed, so make sure your anchor is well dug in. Shelter here is good in all but strong east or south winds. From a dinghy landing on the quay, restaurants line the entire waterfront. Elli’s is one to note, as is Apagio’s — both offering Greek cuisine with an elegant modern twist. Be back aboard and settled before the afternoon Maistros pipes up across the headland.
South of Fiskardo, the eastern coast of Kefalonia unwinds through Agia Efimia and Sami before the long inlet of Argostoli. The approaches to the Gulf of Argostoli from both east and west are full of dangers — under no circumstances should you enter during the dark. In daylight, the port lies at the head of a long, enclosed inlet opening to the south-west, forming one of the most sheltered natural harbours on the island. The entrance is narrow relative to the internal basin, and once inside, conditions are sheltered with minimal sea state and negligible tidal influence. Most visiting yachts moor on the quay immediately south of the customs quay, where depths range from 2.5 metres at the south end to 3.0 metres at the north end. Shelter here is excellent from the prevailing winds but the quay is choppy in strong east winds. Argostoli also doubles as a port of entry to Greece — bring your papers to the harbourmaster’s office on arrival.
Ithaca: Vathy, Kioni and the Silence Between Islands
The crossing from Fiskardo to Ithaca takes under an hour on a moderate powerboat — a straight shot east across the channel that separates the two islands. The reward is one of the great natural harbours of the Mediterranean.
Vathy is the captivating capital of Ithaca and one of the world’s largest and most secure natural harbours. For any cruising skipper, it stands as a legendary destination where Ionian Venetian architecture meets epic mythology. The coastal structure is remarkable, featuring a deep fjord-like entrance that opens into a wide, sheltered bay, providing safe and prestigious anchorage. The tiny Lazaretto islet — once a quarantine station, now a romantic mound of cypresses — marks the centre of the harbour and serves as your arrival landmark.
Anchoring requires attention. The bottom is mud and holding is excellent, but note that anchoring is prohibited within the blue polygon shown on charts. Katabatic gusts spilling down from the steep terrain are common — sometimes strong and localised — making careful positioning and generous scope essential. The most practical berth is on the western quay: boats usually moor at the west pier, which offers about 20 berths marked with yellow lines, where one can moor stern or bow to, dropping anchor on a 3.5–4 metre deep seagrass and mud bottom. Avoid the section nearest the ferry dock — the ships will give you a good shake when they come in, and at night and early morning incoming and outbound ferries generate swell and considerable noise. There is a fuel station at the east end of the harbour bay, open from 08:00 to 20:00, where water can also be supplied.
Kioni, 8 miles north of Vathy on Ithaca’s northeast coast, is the anchorage that gets into your blood. Kioni is one of Ithaca’s most picturesque villages, nestled in a sheltered bay on the island’s northeast coast. The waterfront is lined with tavernas and cafés where you can enjoy fresh seafood with a beautiful view of the bay. Three well-lit windmills grace the southern end of the bay, creating a magical night-time setting. Yachts moor at the quay bow-to or stern-to in water depths of 2.5 to 10 metres — the steeply sloped seabed means a long chain is essential. Alternatively, boats can anchor in the bay or inside the harbour. The golden rule at Kioni: the afternoon does bring strong NW gusts, making mooring stern-to on the quay or longlined to the cliffs challenging with a crosswind. It’s advisable to arrive early, get moored up before battling the wind, and relax while watching other boats coming in later.
Skipper’s Checklist: Practical Intel for the Triangle
This is the distilled operational knowledge the Nautiful team has gathered from season after season in these waters. Keep it open on the chart table.
- D-Marin Lefkas — VHF Channel 69. 620 berths, max draft 4m, fuel dock at marina entrance. Book ahead for July–August.
- Fiskardo — Approach at 38°27’31″N / 020°34’58″E. North shore anchorage 10–12m, lines to stainless rings. Ferry uses north quay — vacate by 11:00. With winds from the south, swell can pick up significantly — avoid this harbour in southerly forecasts.
- Argostoli — Port of entry. Quay depths 2.5–3.0m. Depths are significant throughout the inlet, with the seabed predominantly mud within the inner harbour, providing consistent holding conditions. Never approach the Gulf of Argostoli at night.
- Vathy, Ithaca — Mud bottom, excellent holding. Use the west pier yellow-marked berths, stern-to. Check the anchoring exclusion zone on your Navionics chart before dropping the hook. Fuel and water at the east end station, 08:00–20:00.
- Kioni, Ithaca — Arrive before noon. The entrance is marked by three derelict windmill turrets on the headland. If you want the town quay, early arrival is essential — there is mooring space opposite using shore lines if the quay is full.
- Charts: Carry the Navionics Adriatic & Ionian Sea subscription on your chartplotter and your tablet as backup. The nautical chart includes port plans, anchorage detail and safety depth contours — the baseline for any Ionian passage.
- Provisioning: Argostoli carries the best marine service support on Kefalonia for repairs. Lefkada Town has a full range of chandleries. Lefkada town has a good selection of chandleries and marine equipment suppliers — useful if you need spare parts or gear before a longer passage south.
Swimming Spots and Tender Runs: What Only a Boat Can Reach
The beaches the land tourists never find — that is the promise the Ionian makes to every skipper who drops anchor in the right place. South of Fiskardo, a series of fjord-like coves cut into the limestone cliffs of northern Kefalonia. They have no roads, no car parks, no tavernas. You reach them by tender, tie a line to a boulder, and swim in water so clear that the anchor chain is visible at ten metres depth.
Off Ithaca, the anchorage at Filiatro Beach on the island’s east coast is reachable only from the water. Anchor freely on sandy bottom at about 8 metres depth or run stern lines to the northern or southern rocks. The northern beach is accessible only by sea — anchor freely on sand or pass stern lines to the rocks behind the beach. On the western coast of Ithaca, Polis Bay is a lovely anchorage perfect for a lunchtime stop or overnighting, with lots of space for either free-swinging or shore lines.
In the waters around Nidri, the scattered islets of Meganisi, Sparti, and Skorpios create a network of secluded coves. When you base yourself at Nidri, you unlock access to hidden gems and beautiful beaches that can only be reached by water, allowing you to discover the true beauty of Lefkada and its neighbouring islands. The Onassis island of Skorpios sits just 3km offshore — its white pebble beaches visible from the helm but utterly out of reach without a boat.
Planning Your Circuit: The Classic Ionian Triangle
The Greece Ionian Islands sailing guide: Lefkada, Kefalonia and Ithaca circuit works beautifully as a one-week itinerary from D-Marin Lefkas, and Nautiful recommends running it broadly anti-clockwise: south down Lefkada’s east coast to Nidri, across to Fiskardo, south to Argostoli, east to Vathy on Ithaca, north to Kioni, then the crossing back to Fiskardo before heading home past Meganisi and into Lefkada. That gives you seven passages, none longer than 25 nautical miles, with anchorages at both ends of every day.
For charter operators, Lefkada is the established base. D-Marin Lefkas Marina is the perfect starting point to discover the special islands of the Ionian Archipelago, just to the west of mainland Greece. If you’re arriving on your own boat, consider using a marina booking platform to secure berths at D-Marin and Argostoli well in advance of peak season — spaces at both fill rapidly after mid-June and the price premium for a confirmed berth is almost always worth it versus circling a packed harbour at 16:00 with a 30-knot Maistros on your beam.
Whatever size boat you are running — a Jeanneau Merry Fisher 895, a Beneteau Gran Turismo 46, a Princess V50 — the southern Ionian rewards skippers who move early, anchor often, and resist the pull of the marina when a cove offers something better. The Ionian Sea is one of the Mediterranean’s most predictable sailing destinations, thanks to the Maistros thermal wind system following a reliable daily cycle, an island-dense geography that limits fetch, and stable summer high-pressure systems that suppress storm risk. Together these conditions create manageable, forecastable weather — making the Ionian an ideal choice for both first-time and experienced charter guests.
This is the corner of the Mediterranean where the Greece Ionian Islands sailing guide: Lefkada, Kefalonia and Ithaca finds its truest expression — not in any single anchorage or harbour, but in the whole breathing, sun-warmed circuit of them. Plan it carefully, navigate it with a current Navionics chart loaded and an honest eye on the Maistros, and you will come back. Everyone does.
