Driving to France gives you freedom that flying can't match — your own car, no luggage limits, and the flexibility to stop wherever you want. But the costs add up if you don't plan carefully. Here's how to keep the total as low as possible.
1. Choose the Right Crossing for Your Location
The cheapest ferry crossing means nothing if you spend £60 in fuel getting to the port. Your starting location in the UK makes a huge difference.
South East England
Dover ferries or Eurotunnel are your best bet. Short drive to port, cheapest crossings.
South West England & Wales
Portsmouth or Plymouth ferries save hours of driving east. Portsmouth to Caen or Cherbourg puts you straight into Normandy.
Midlands & North
It's a long drive to any port. Compare the total cost of driving to Dover vs Portsmouth — the fuel savings from a closer port might offset a pricier ferry.
2. Book Early and Travel Off-Peak
Crossing fares swing dramatically with demand. A Dover-Calais ferry can cost £55 in February but £160 in August. Eurotunnel ranges from £89 to £249+. Booking 2-3 months ahead typically locks in the best rates.
Tip: Mid-week crossings (Tuesday/Wednesday) are almost always cheaper than weekends. If you can be flexible on dates, check prices across a few days either side.
3. Minimise French Toll Costs
French autoroute tolls are one of the biggest hidden costs. Here are your options:
| Strategy | Savings | Trade-off |
|---|---|---|
| Take national roads (routes nationales) | 100% toll savings | 50-100% longer journey time |
| Mix motorway and national roads | 40-60% toll savings | 20-40% longer |
| Choose toll-free regions (Brittany, Alsace) | Varies by route | May add distance |
| Get a Liber-t toll tag | Saves time, occasional discounts | €2/month subscription |
4. Save on Fuel
- Fill up before crossing — UK fuel is sometimes cheaper than French motorway services
- In France, supermarket fuel stations (Leclerc, Carrefour, Intermarché) are consistently 10-15 cents/litre cheaper than autoroute stations
- Plan fuel stops off the motorway — a 2-minute detour can save £10+ per fill
- Check tyre pressure before departure — correctly inflated tyres improve fuel economy by up to 3%
5. Consider Whether Driving Is Actually Cheapest
For long-distance French destinations, flying with car hire can be surprisingly competitive. A return flight to Nice plus a week's car hire might cost less than fuel + tolls + crossing + wear on your car. It's worth comparing both options before committing.
