There is no drama to crossing from France into Italy by boat. One minute you are off Menton looking back at the French Alps tumbling into the sea, the next you are abeam Ventimiglia and the architecture has changed colour. The frontier is a line on the chart and nothing on the water. That is exactly why the Ligurian hop is one of the most relaxed pieces of France to Italy sailing you can do: short legs, settled summer weather, and a string of harbours close enough that you never have to commit to a long passage.
We did this run over ten days in June aboard a 38 foot cruiser, and I would happily do it again tomorrow.
The shape of the coast
The far eastern end of the Cote d'Azur stacks ports tightly. From Nice it is roughly 12 nautical miles to Monaco, another 8 or so to Menton, and then under 5 miles across the border to the first Italian harbour at Ventimiglia. Sanremo, the unofficial capital of the Italian Riviera dei Fiori, lies about 12 nautical miles east of the frontier. None of these is a passage in any serious sense; they are afternoon sails.
If you are coming from further west, the natural warm-up is the Monaco to Saint-Tropez cruise in reverse, building east along the coast and using the dramatic Cap Ferrat and Villefranche bays as overnight stops before you reach the border. I would not rush past them. Villefranche has one of the deepest natural anchorages on the coast and is a fine place to sit out an unsettled day.
Crossing the border in practice
France and Italy are both in the EU and the Schengen area, so for an EU-registered boat with EU crew the crossing involves no formalities at all. You do not need to clear out of France or into Italy, and there is no customs post to visit. We simply changed our courtesy flag from the French tricolour to the Italian one as we passed Ventimiglia.
It is not quite that frictionless for everyone. If your boat flies a non-EU ensign, or you have non-EU crew aboard, the rules tighten. The boat's temporary admission status and the crew's Schengen days both carry across the frontier, so keep your documents in order. British boats in particular need to be careful here, and the bringing a UK-flagged boat to France after Brexit guide explains why your time in EU waters now matters in a way it did not before 2021. The same clock keeps ticking in Italy.
One Italian quirk worth knowing: Italy has historically required private boats to carry certain documents and, for some craft, to log arrivals. In practice, EU yachts moving along the Riviera are rarely troubled, but carry your registration, insurance and a crew list, the same paperwork the Gendarmerie Maritime checks on the French side.
How the Ligurian Sea actually sails
The Ligurian Sea in summer is mostly a sea breeze affair. Mornings are often calm, a thermal breeze fills in from the south or south-west by early afternoon, typically 10 to 15 knots, and it dies away in the evening. That rhythm makes for civilised day sailing: motor out in the flat morning, sail the afternoon, tie up before the breeze drops.
The wind to fear is the same one that haunts the French coast. The mistral does reach round into the Ligurian, and the local libeccio from the south-west can build a heavy swell against this north-facing shore with little warning. There is no shelter from a southerly here, so I never left a harbour without checking the forecast properly. If you are new to reading Provencal weather, the mistral, reading it before it traps you piece is the one I wish I had read on my first season, because the warning signs are subtle until they are not.
Depths drop away fast on this coast. The 100 metre contour sits close inshore in many places, which is why the anchorages are few and the marinas are the norm. That has a cost, which brings us to money.
What it costs
The Riviera, French and Italian, is expensive, and August is the worst of it. Some honest figures from 2025-2026 to plan around:
- A 12 metre boat in a French Cote d'Azur marina in high season commonly runs 80 to 150 euros a night, and the glamour ports charge well beyond that.
- Monaco's Port Hercule is in a league of its own; a visitor berth in season can run into several hundred euros a night for a mid-size yacht, if you can get one at all.
- On the Italian side, Sanremo's Portosole and the marina at Ventimiglia are dear in July and August but generally a notch below the French equivalents.
- Diesel either side of the border tracks national pump prices; Italy's marina fuel berths often sit a little above the French ones.
The French marina picture, with its booking quirks and the August scramble, is worth understanding before you go; the Cote d'Azur marina fees breakdown saved us from a couple of nasty surprises. Book ahead for August or accept that you may be anchoring off and dinghying ashore.
Provisioning across the border
One of the quiet pleasures of this hop is that you provision in two food cultures within a single week. The French side, with its harbour markets and boulangeries, is set up for exactly this kind of stop-and-shop cruising, and the provisioning a boat in France from the markets routine carries straight across to the Italian Riviera, where the difference is mostly that the cheese counter changes nationality and the wine gets cheaper. We loaded up on Provencal staples in Menton, then restocked fresh pasta, tomatoes and Ligurian olive oil in Sanremo's covered market the morning after we crossed.
Water and fuel need a little planning because the harbours are close together but not all carry a fuel berth. We topped up diesel on the French side before crossing, partly out of habit and partly because the paperwork around bunkering is more familiar there. Visiting boats sometimes ask about duty arrangements; the rules on duty-free and red diesel in France for visiting boats are stricter than the old days, and you should assume you are buying fully taxed white diesel either side of the border unless you have specific entitlement. Water is free or a token charge at most of these marinas, so we simply filled the tank whenever we found a tap.
A suggested ten-day run
Here is roughly what we did, and it flowed well:
- Days 1 to 2: Nice, with a night at anchor in Villefranche.
- Day 3: Monaco for the spectacle, then a short hop to Menton.
- Day 4: cross the border to Ventimiglia, change the flag, find an Italian cafe.
- Days 5 to 6: Sanremo, the flower markets, the old town up the hill.
- Days 7 onward: push east along the Riviera dei Fiori towards Imperia and beyond.
You can keep going as far as your time allows. Liguria opens into the Gulf of Genoa, the Cinque Terre and eventually the whole Tyrrhenian, and the Ligurian hop is really just the first chapter of a much longer eastward voyage.
Where it leads
The reason this coast matters is that it is a gateway. Cross into Italy here and you can keep working east towards the Tuscan archipelago, or turn south and use the islands to reach Sardinia. If Sardinia is your aim, the cleaner route runs down through Corsica, set out in the France to Sardinia and the Tyrrhenian guide, rather than the long open crossing from the Italian mainland. And if the Riviera is only your jumping-off point for something bigger, the France as a stepping stone to the Mediterranean overview shows how this short border hop connects to the wider voyage.
The Ligurian hop is the gentlest international crossing in the Mediterranean. Pick your weather, keep your papers tidy, and the only hard part is leaving.
