There is a very specific moment in any passage south through the Ionian when three islands come into view simultaneously — the green-cloaked cliffs of Lefkada to the north, the broad mountain mass of Kefalonia filling the horizon ahead, and the compact spine of Ithaca rising between them to the east. The water goes suddenly cobalt, the afternoon breeze lays a clean chop across the bow, and you understand immediately why every experienced Med skipper returns here season after season. This is your Greece Ionian Islands Sailing Guide: Lefkada, Kefalonia and Ithaca — written entirely from the helm, for the helm.
Reading the Ionian Before You Arrive
The southern Ionian rewards those who understand its rhythm. The Ionian’s remarkable weather consistency comes from three interlocking factors: a daily thermal breeze called the Maistros that cycles from May to September, an island chain that physically shields the region from the stronger Aegean winds, and a summer-long Mediterranean high-pressure system that suppresses storm risk. For motor boaters, this translates into something deeply practical. The Maistro is a mild-mannered NW wind delivering a reliable and steady breeze from late May to late September — in the height of summer, it is said you can set your watch to the wind: not a breath before 11am, then a gradually building medium breeze ideal for a relaxed afternoon passage, before the wind goes to sleep shortly before dusk.
That daily pattern dictates your itinerary. Mornings are often calm and perfect for motoring. Afternoons run 12 to 20 knots, with peaks to 25. On an express cruiser — a Jeanneau Leader 10.5, an Axopar 37, or a Greenline 45 — you use the morning calm for longer hops and arrive at your anchorage before the chop builds. At night, cooler air slides down from mountain slopes — especially on Kefalonia — causing brief gusts in anchorages. On hot summer days, the land-sea temperature difference can enhance the Maistro, making afternoons breezier than forecasts predict. Load Navionics Boating on your chartplotter or tablet before departure — the Adriatic and Ionian Seas subscription covers this entire region with sonar-updated bathymetry and anchorage overlays that no paper chart matches for detail. With up to 5,000 daily chart updates, you access the most precise and up-to-date information, with features like suggested dock-to-dock routes and real-time HD depth map updates while on the water.
Lefkada: The Canal, D-Marin and the Sheltered East Coast
Approaching from the north — say from Preveza or the Ambracian Gulf — your first challenge in this Greece Ionian Islands Sailing Guide is the Lefkada Canal. 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. The swing bridge at the southern end of the channel is the gating event: from 08:00 to 22:00 there is a full rotation every hour. From 23:00 to 07:00 the bridge also rotates, only if there is a vessel waiting, on request via VHF 12. Miss the slot and you wait an hour in 35°C heat — plan accordingly and do not dawdle on approach.
South of the bridge, D-Marin Lefkas Marina is the most comprehensive facility in the southern Ionian. The marina lies inside a long L-shaped wavebreak pontoon that shelters the berths from E and N. Entry is from the south between the wavebreak pontoon and the jetty with the fuel berth at its end. Contact the marina via VHF on arrival on channel 69 — a good habit you’ll use at every port on this circuit. The total capacity is 620 berths up to a maximum length of 45 metres and a draft of 4 metres. Depths alongside are generally 3–5 metres with stern-to berthing on laid moorings. Berth fees in high season are among the steepest in the southern Ionian, though the facilities justify the cost for a night’s turnaround — fuel, water, electricity and full technical support are all on hand.
For motor boaters, Lefkada’s east coast is the working playground. Vlicho Bay, a long sheltered natural bay just south of Nidri, offers calm waters and excellent protection from all wind directions, making it one of the safest anchorages in the Ionian even during strong blows — popular among cruisers for extended stays thanks to easy anchoring, good holding, and proximity to yacht services. Along the Vlicho shore you’ll find tavernas, small shops and repair facilities, while Nidri is only a short dinghy ride away for more extensive provisioning. The western coast of Lefkada — Porto Katsiki, Egremni — is a different story: spectacular scenery and famous beaches but few safe stops, making it suitable mainly for fair-weather daytime visits. Bring the dinghy, bring sunscreen, go in the morning, and leave before the swell wraps around.
Kefalonia: Fiskardo to Argostoli — The Big Island Done Right
The passage from Nidri or Vlicho to Fiskardo at the northern tip of Kefalonia runs roughly 15 nautical miles south-southeast — a gentle morning run in flat water with Meganisi to port. Fiskardo is a charming and well sheltered small harbour at the NE end of Kefalonia. The port offers good shelter from the prevailing NW winds, and just enough shelter from the south and southeast. The small harbour is almost always crowded and it pays to arrive early, especially during the peak months of July and August.
Your berthing options at Fiskardo, in priority order: at the breakwater (depths 3.5–4 metres), at the south dock (caution: depths of only 1–1.5 metres maximum), and at the west dock (depths 2–3 metres). If the quay is packed — and in July it will be — head for the northern anchorage. Along the N 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 is good in all but strong E or S winds. The harbourmaster keeps the ferry quay and tripper boat quay free until late afternoon — don’t be fooled by a large empty space.
South of Fiskardo, the Kefalonian coast rewards patient exploration under power. Foki, the first inlet south of Fiskardo without major tourist development, is frequented by Mediterranean monk seals — anchor in 3–5 metres. Assos Bay offers perhaps the most spectacular setting, with its narrow entrance opening into a well-protected circular bay. The surrounding cliffs provide complete wind protection, though space is limited to around 10–12 yachts. The bay maintains consistent depths of 4–8 metres with excellent holding in sand and weed. Approach Assos with Navionics running and your eye on the depth sounder — the entrance requires a clean line, and the rewards are worth the attention. The Kefalonia subscription under the Adriatic and Ionian Seas chart region gives you the bathymetric resolution to thread this coast with confidence.
If you need full services on Kefalonia, continue south to Argostoli — but approach the Gulf of Argostoli with care: the approaches from both E and W contain dangers and should never be entered after dark. The port supports 200+ berths with access to water, electricity, fuel, sanitary facilities, chandlery and technical services, making it the only location on the island with meaningful yacht support capability. For provisioning, Argostoli provides the most comprehensive reprovisioning on Kefalonia, with multiple major supermarkets including AB Vasilopoulos, Lidl and Sklavenitis. Run the dinghy in, load the cool boxes, and you’re set for the passage to Ithaca.
Ithaca: Vathy, Kioni and the Fjord-Like Bays Only Boats Can Reach
Ithaca is one of the most distinctive sailing destinations in the Ionian, offering exceptional natural shelter within a compact and mountainous island. Its coastline is deeply indented, forming narrow bays and fjord-like inlets that provide protection in conditions where more open islands become uncomfortable — a natural haven for sailors for centuries. In a motor boat, this translates into something rare in the Mediterranean: sheltered anchorages with extraordinary depth changes that keep the charter fleet out and the serious skipper rewarded.
Vathy, the main harbour and administrative centre of Ithaca, lies at the head of one of the most naturally sheltered bays in the Ionian Sea. Vathy provides anchoring in 5–10 metres over mud with reliable holding and high shelter from all directions. Boats moor at the west pier, which offers about 20 berths, bow or stern-to, over a 3.5–4 metre mud and seagrass bottom. There is a fuel station at the east end of the harbour bay, open 08:00 to 20:00, where water can also be supplied. The afternoon sea breeze funnels down the inlet and is usually only uncomfortable until the afternoon seabreeze — which can reach F4–5 in summer — dies down. Rig a snubber and set the hook properly in the mud; once dug in, Vathy holds.
Four miles north by water lies Kioni, and the contrast could not be sharper. Kioni is one of the most beautiful harbours in the Ionian: an amphitheatre of pastel houses, terraced olive groves and waterfront tavernas curving gently around a deep, sheltered bay. Approaching from north or east you’ll spot the old windmills on the southern headland at the entrance to the bay — line them up and motor in. Yachts moor at the quay bow-to or stern-to at water depths of 2.5 to 10 metres; the steeply sloped seabed means it makes sense to use long chain. Alternatively, anchor in the bay — but the seabed is unreliable in places and boats should also be secured with shore lines. There is no fuel at Kioni — top up before arrival. Closest fuel is at Fiskardo or Sami. Get there by early afternoon: Kioni fills early — late arrivals find themselves anchored further out with a longer dinghy ride.
Passages, Timing and the Motor Boater’s Edge
Motor boaters have one significant advantage over the sailing fleet on this circuit: timing independence. When the Maistro builds to 20 knots on a W–NW bearing at 13:00, a performance motor boat powers through the chop while the sailing fleet decides whether to reef. The passages between these three islands — typically running 10 to 25 nautical miles apart, or two to five hours — suit a twin-engine RIB, an Axopar 37 Cross Cabin, or a Jeanneau Merry Fisher 1095 Fly equally well. The summer chop generated by the afternoon Maistro across the open Kefalonia–Ithaca channel can reach short, steep 0.5–1-metre seas by 15:00 — comfortable in a deep-vee hull, wearying in a flat-bottomed pontoon. Plan your inter-island passages for 09:00–12:00 and spend the afternoon at anchor.
The Lefkada–Kefalonia–Ithaca triangle also lends itself perfectly to a bareboat motor charter structured around a seven-night loop: D-Marin Lefkas as base, two nights on Kefalonia (Fiskardo and Assos or Argostoli), two nights on Ithaca (Kioni and Vathy), and the return north via Meganisi and Vlicho. When booking, charter operators including Sailing Greece and Ionian Sailing base fleets at D-Marin Lefkas specifically for this circuit — confirm berth reservations at D-Marin in July and August well in advance. Book your D-Marin berth well in advance for July and August — the marina fills quickly during peak charter season.
What You Can Only Reach by Boat
This is the core truth of every Greece Ionian Islands Sailing Guide: the best of this coast is invisible from any road. The pebble beach inside Assos Bay, Foki’s sea caves and their resident monk seals, the coves south of Fiskardo — the exceptional water clarity, often exceeding 30 metres of visibility, allows you to see your anchor and assess the seabed conditions easily. You drop the hook in 5 metres of gin-clear water and look straight down at white sand. No hotel, no taxi, no landward path reaches where you are.
On Ithaca, the clearest water that sailors report is at spots accessible only by boat and teeming with fish — shallow caves and cliff-backed coves along the western shore that are unmarked on any tourist map. Bring masks and fins, run the dinghy in close, and accept that these places have no names worth printing — they’re marked only by the quality of the light on the water at 17:00.
For dining reachable by tender: at Kioni, the waterfront tavernas serve freshly caught seafood, grilled octopus and Ionian mezze — step off the dinghy and you’re at a table. In Fiskardo, the quayside restaurants are accessible directly from the breakwater berth; expect premium prices and excellent fresh fish. At Vathy on Ithaca, a well-stocked supermarket sits 50 metres from the south end of the yacht quay, while several excellent tavernas line the harbour with rotisserie meats and traditional Ithacan cooking.
The Nautiful Verdict: Plan It, Load the Charts, Go
The Lefkada–Kefalonia–Ithaca triangle is not merely a Greece Ionian Islands Sailing Guide destination — it is the definitive introduction to Med motor boating for anyone who hasn’t done it, and the destination serious skippers return to because nowhere else in the Mediterranean combines sheltered overnight anchorages, civilised marinas, breathtaking scenery and reliable summer weather within passages short enough to leave time to actually swim. Load your Navionics Boating subscription for the Adriatic and Ionian Seas before departure. Pre-book your D-Marin Lefkas berth for any July or August arrival date. Confirm Agia Effimia on Kefalonia via VHF 74 with the harbourmaster on approach. And set your alarm for 08:30 — the canal bridge opens on the hour, the Maistro is still asleep, and the sea between here and Fiskardo is flat, blue and entirely yours.
Stay close to the water, stay ahead of the afternoon breeze, and never underestimate how good a cold Mythos tastes when you’ve anchored somewhere a road will never reach.
