We bought a 12-metre steel cruiser in Saint-Jean-de-Losne in the spring of 2022 with almost no idea what we were doing. My wife had handled a narrowboat once on the Llangollen for a long weekend in 2015. I had crewed on a friend's yacht in the Solent and thought that counted for something. It did not. The first time I tried to hold our boat steady in a lock chamber while the water dropped, I learned more in ninety seconds than in any book I had read over the winter.
Four seasons on, we have done something like 900 km of French canals and rivers, from Burgundy down to the Mediterranean. This is the guide I wish someone had handed me before we started. It is long, because the French inland waterways reward a bit of homework, and the gaps in your knowledge tend to show up at the worst moments.
What the French canal network actually is
France has roughly 8,500 km of navigable inland waterways, the largest connected network in Europe. Some of it is canal in the proper sense, dug by hand or machine, dead flat between locks. A lot of it is canalised river: the Saone, the Rhone, the Seine, the Lot in places, where the natural river has been tamed with locks and weirs so you can cruise it. The two feel completely different to drive. A narrow canal at walking pace through Burgundy vineyards has nothing in common with the Rhone, where commercial barges push past you and the current can run at several knots.
For a newcomer the headline routes are the ones you have probably heard of. The Canal du Midi by boat is the famous one, 240 km of plane-shaded water from Toulouse to the Etang de Thau near Sete, finished in 1681 and on the UNESCO list since 1996. The Canal de Bourgogne climbs through some of the prettiest countryside in France. The Canal de la Marne au Rhin has the extraordinary Arzviller boat lift. And then there is the through-route, Channel to the Mediterranean, that lets you take a boat from Calais or Le Havre all the way down to the south of France without ever going to sea.
Do you need a licence?
This is the first question every British and Antipodean visitor asks, and the answer depends entirely on whether you hire or own.
If you hire a boat, you need no licence at all. The hire company gives you a briefing at the base, an hour or so of theory and a short practical run, and issues you a temporary authorisation valid for your trip. That is it. Tens of thousands of people who have never driven a boat take a hire cruiser out every season on exactly this basis.
If you bring or buy your own boat, it is different. For a private boat under 20 metres on the French inland waterways, the skipper is expected to hold an International Certificate of Competence (ICC) endorsed for inland waters, which means you also have to pass the CEVNI test. CEVNI is the European code of signs, signals and rules for inland navigation, and it is genuinely different from the buoyage you learn for the sea. I sat the CEVNI test at an RYA centre over a winter evening before we left the UK. The ICC is valid for five years. I have written a fuller piece on the ICC and CEVNI for French waterways because the detail trips people up.
Boats over 20 metres need a higher category of licence. Most visitors are well under that.
The VNF vignette: paying to use the water
You cannot just turn up and cruise. The waterways are managed by Voies Navigables de France (VNF), and using them with a private boat means buying a vignette, which is essentially a toll permit.
The vignette is required for any craft over 5 metres long or fitted with an engine of 9.9 HP or more. The price is worked out from your boat's length and the package you choose. VNF sells short packages (a single day, a 16-day holiday package, a 30-day package) and the annual Liberte package for people staying the whole season. To give you a sense of scale, the annual permit for a 10-metre boat was around 322 euros in 2024, and a 20-metre barge paid roughly 752 euros for the year. Prices rose again for 2025 and 2026, so budget a little more.
There are real discounts worth knowing about. Buy the annual Liberte package early, before the end of March, and you save a chunk. Zero-emission boats get a 50% reduction and boats running on HVO biofuel get 25%, on proof. I cover the whole thing, including how to buy online, in my guide to the VNF vignette and what it costs.
How big a boat can you take?
The thing that catches sea sailors out is that the canals impose hard limits, and they are not generous. Most of the older network was built to the Freycinet gauge, a standard set by a law of 1879. A Freycinet barge could be no more than 38.5 metres long, 5.05 metres wide, with a draught of 1.8 metres. The locks themselves are 39 metres by 5.2 metres.
For a leisure boat the numbers that matter day to day are beam, draught and air draught. If your boat is wider than about 5 metres you are locked out of much of the smaller network. Draught matters because canals silt up and the advertised depth is rarely what you get near the banks. And air draught, the height from the waterline to your highest fixed point, decides whether you fit under the bridges. The standard bridge clearance on the Freycinet canals is 3.7 metres, and many older bridges give you less. Our cruiser sits at about 3.1 metres air draught and we have still held our breath under a few hump-backed stone bridges in Burgundy.
If you are bringing a yacht down from the sea, the mast comes off and travels on deck on a frame. That alone is a project. People underestimate it.
Locks: the heart of the whole thing
You will spend a large part of your canal life going up and down in locks. On the Canal du Midi alone there are around 91 working locks across those 240 km. A busy day on the Burgundy summit might mean a dozen or more.
A French lock is not complicated once you understand the sequence, but the first few are stressful. You approach, you get a rope around a bollard or a ladder, you hold the boat against the surge of water, the gates open at the other end, you motor out. Some locks are automated and you trigger them yourself with a twist-pole or a remote. Many on the Midi and in Burgundy still have a human lock-keeper, the eclusier, who often sells honey, wine or vegetables from a table by the gate. I wrote a step-by-step piece on how a French lock works because the mechanics genuinely deserve their own explanation, and getting it wrong damages your boat or somebody else's.
Lock opening hours are the rhythm of your day. Most locks work roughly 9am to 7pm in high season with a firm lunch break, usually 12.30 to 1.30, when everything stops. Plan to be moored or waiting through lunch, because nothing moves and the eclusier will not thank you for arriving at 12.29.
What it costs to actually do this
Beyond the boat itself and the vignette, the running costs are gentler than coastal cruising. Diesel consumption at canal speeds is tiny because you rarely go above 6 to 8 km/h. Overnight moorings range from free (a quiet stretch of bank with bollards) to maybe 10 to 25 euros a night at a proper halte nautique or town quay with water and electricity. Many small-town moorings are still free or only charge for power.
Compare that with hiring, where a week on a mid-size cruiser in shoulder season runs from around 1,500 euros and a large boat in peak August can pass 4,000 or even approach 5,000 euros. If you want to test the life before committing to ownership, hiring first is the sensible move, and I have weighed up hiring versus bringing your own boat on the French canals in detail.
A realistic first trip
If this is all new, do not try to cross France in a fortnight. Pick one canal, hire a boat, and go slowly. A classic first week is a one-way run on part of the Canal du Midi, or a loop in southern Burgundy. Aim for four or five hours of cruising a day at most. You will want time to walk into villages, buy bread, sit at a lock and watch the eclusier work.
The mistakes we made early on were all about haste: trying to do too many kilometres, arriving at locks too close to lunch, mooring too late and finding the good spots taken. The canals run on a slow clock. Once you stop fighting it, the whole thing becomes the holiday you actually wanted.
A short checklist before you go
- Decide hire versus own. Hire needs no licence; owning needs an ICC with CEVNI endorsement if your boat is under 20 metres.
- If you own, buy your VNF vignette before you start, online, and grab the early Liberte discount if you are staying the season.
- Check your boat against the bridges and locks on your chosen route: beam under about 5 metres, air draught comfortably under 3.5 metres, draught under what the canal really offers.
- Learn the lock sequence and carry proper lines, fenders and gloves.
- Build your day around lock hours and the lunch closure, not the distance you hope to cover.
We are heading back out in June, this time onto the Canal du Nivernais, which everyone says is the loveliest of the lot. Four years in, the planning still takes a winter. That is part of the pleasure.
