We spent eleven weeks on the French canals in the summer of 2023 and paid for a berth on exactly nineteen of those nights. The rest were free. That single fact is the thing nobody tells you when you are saving up for a canal boat and bracing for the cost. On the inland network, the default is that you tie up where you like, at no charge, against a grassy bank or a stone quay, and watch the evening come in for nothing.
It surprises people coming off the coast, where a marina berth on the Atlantic or the Med can swallow 40 to 70 euros a night in season. The canals run on a different economy. Here is how it actually works.
The three kinds of place you can spend the night
Most overnight spots fall into one of three categories, and the difference matters for your wallet.
First, the wild or informal mooring. You find a stretch of bank with deep enough water and somewhere to bang in your stakes or loop a line round a tree, and you stop. The majority of moorings on the network are free, and it is generally fine to tie up temporarily along the canal side away from locks, bridges and bends. We did this most nights. It costs nothing and it is where the best memories are.
Second, the halte fluviale or halte nautique. This is a small quay or pontoon laid on by the local commune, usually near a village. Some are completely free. Many have water and electricity for a token charge, often under 10 euros a night in the quieter villages. Facilities range from a single tap to proper showers and a waste point.
Third, the port de plaisance. These are run by municipalities or hire-boat companies, with power, water, sometimes showers and occasionally fuel. Expect to pay more here. Crossing Brittany and staying a few nights in a 9-metre boat ran us about 18 euros a night, and a couple of busier ports charged up to 23 euros in high season.
What "free" really means
Free moorings are genuinely free, but they are not serviced. No water, no power, no bin. You are self-sufficient or you are not staying. We carried enough water for four days, ran the fridge off solar and a battery bank, and kept rubbish bagged until we hit a halte with a bin. That rhythm became second nature within a fortnight.
The trade-off is solitude. Some of our finest nights were tied to a field with cows for neighbours and not another boat in sight. The trade-off the other way is that when you do want a hot shower and a top-up of water, you go looking for a serviced halte and pay the small fee gladly.
The unwritten rules of tying up
A few things I learned, some the hard way.
Do not moor in a lock approach or on a bend. Working boats and hire boats need the room, and the wash from a passing peniche against a tight bank will jolt you out of your bunk. Stay 100 metres clear of locks.
Use proper bank stakes and a mallet if there are no bollards or rings. We carried two 60-centimetre steel pins. Trees are tempting but the roots and the chafe will cost you in the end.
Check your depth at the edge before you commit. The canals carry far less water at the bank than in the middle, and the Freycinet gauge canal dimensions you read about are a midstream promise, not an edge guarantee. We grounded twice trying to get cosy against a shallow bank.
Be quiet after about nine in the evening. Generators in particular earn dirty looks. The whole appeal of a free mooring is the silence, and the unspoken deal is that you keep it.
Budgeting a season
Here is roughly how the money landed for us over eleven weeks, two adults, a 12-metre boat.
- Moorings: under 350 euros total, because most nights cost nothing.
- The VNF licence (vignette): a few hundred euros for the season, scaled to boat length. A 10-metre boat paid a little over 320 euros for an annual pass in 2024, with a 20 percent discount for ordering the year-round package before the end of March.
- Diesel and gas: more than we spent on moorings, frankly, though canal cruising sips fuel at 6 km/h.
The headline is that mooring is the cheapest part of canal life. If you have come from coastal cruising, budget for the VNF vignette and the licence paperwork and treat overnight stops as close to free.
Finding the good spots
The skill that pays off most is reading a stretch of bank from the boat. You want deep water close in, which usually means a stone-faced quay, a section where working boats once loaded, or the outside of a gentle straight rather than a shelving grass bank. We learned to slow right down and watch the depth sounder along the edge before committing the bow.
Villages are the obvious target because they bring a boulangerie, a bin and often a tap, but the most memorable nights were nowhere near a village. A bend with a long-disused loading quay, an old lock layby, a field gate with a ring set in the stone: France is full of these, and once your eye is in you start spotting them a kilometre off.
A few we returned to specifically because they were so good: a free quay under a chateau on the Canal du Nivernais, where we tied up beneath the walls and watched the light go; and a grassy bank on the Breton canals with nothing but cattle for company. Neither cost a centime.
Services without a marina
You do not need to pay for a port just to keep the boat running. Water is the main thing you go looking for, and you find it at serviced haltes, at the better village quays, and sometimes at a lock cottage if you ask the keeper politely. Many haltes use a token or a card system, often a euro or two for a slug of water and electricity, sometimes free.
For waste, the network is improving but patchy. Black-water pump-out points are still thinly spread compared with British or Dutch standards, so plan refills and dumps around where the facilities actually are rather than where you happen to be. We kept a running list and treated a pump-out point like a fuel stop: take it when you pass it, do not wait until you need it.
Electricity matters less than you think if you set the boat up for it. Solar on the roof and a decent battery bank meant we ran the fridge, lights, laptops and water pump for days at free moorings without a hookup. The boats that struggle are the ones that need shore power every night, and those are also the ones paying for a port every night.
A simple plan for your first week
Aim to free-moor most nights, then book or seek a serviced halte every third or fourth night to refill water, dump rubbish and grab a shower. Carry enough water and power to make that work. Keep a paper or app list of haltes with services along your route, because they are not evenly spaced and you do not want to discover the only bin for 20 kilometres is behind you.
Do that and the canals become one of the cheapest, most beautiful ways to live afloat in Europe. The mooring, more often than not, is the part you do not pay for.
