Prices below are the state of play as of 2026 and they drift with season, fuel and booking date. Treat them as scale, not gospel, and check the operator before you commit real money.
Getting across
Dover–Calais is the workhorse: about 90 minutes at sea, sailings through the day with P&O and DFDS, and motorhome fares that commonly land between £80 and £150 each way when booked ahead. LeShuttle from Folkestone does it in 35 minutes and takes motorhomes up to considerable sizes, priced by date and flexibility. Figure on it usually costing more than the boat, sometimes a lot more in August. Bottled gas is fine on both, turned off, and the tunnel checks at boarding. Vehicles actually propelled by LPG can't use the tunnel at all.
If the destination is Spain or Portugal, do the sum on the long crossings before defaulting to Calais. Brittany Ferries runs Portsmouth to Bilbao and Santander, 29–33 hours at sea, vehicle fares from around £231 before you add a cabin. A loaded return in season can run well into four figures. Set that against roughly 600 miles of French diesel, tolls and overnights each way, plus two days of driving, and the ferry stops looking expensive and starts looking like a bought day of holiday. Heading east instead, Stena's overnight Harwich–Hook of Holland crossing drops you within a morning's drive of Germany.
The aires system
France's aires network is the reason touring there is cheap. Thousands of designated motorhome stopovers, many free, the paid ones typically €5–15 a night, sited in villages, ports and market towns rather than out on ring roads. Most have a service borne for water and waste. Budget a few euros for around 100 litres of fresh, with emptying nearly always free. The unwritten rules keep the network alive: stay a night or two, not a week, keep wheels on your own pitch rather than an awning-and-chairs encampment, and spend something in the village. Italy runs the same idea as sostas, Germany as stellplätze. Spain has fewer but they're spreading.
Tolls: pay, tag or dodge
French autoroutes charge by vehicle class, and motorhomes straddle the line that matters. Under 3 metres tall and under 3.5 tonnes, you're Class 2, paying roughly €0.10–0.15 per kilometre. Go over 3 metres in height or over 3.5 tonnes and you're Class 3, at roughly €0.20–0.25. The height measurement includes permanent fixtures like air conditioning pods, though not aerials. Measure your van before you go, because a Calais–Mediterranean run is comfortably north of €100 in tolls for a Class 2 van and roughly double in Class 3.
Electronic tags (Emovis, Ulys and the like) spare you the ballet of reaching a left-hand-drive toll machine from a right-hand-drive cab, and they work across France and into Spain. The catch: as of 2026 the standard tags are officially issued for vehicles up to 3 metres and 3.5 tonnes. Bigger or heavier vans are pointed at HGV-class tags from outfits like Eurotoll, which cost more and suit full-timers better than fortnight tourers. The free alternative is the N-road network, which is slower, passes through towns, and reliably serves a better lunch. Plenty of tours mix the two: péage for the long transit south, N-roads once the holiday starts.
Fuel and gas
Diesel prices vary more between countries than new tourers expect. Spain runs consistently cheaper than France (the gap has often been 20–40 cents a litre in recent years), so a Pyrenees crossing on fumes is a strategy, not an accident. Within France, supermarket forecourts are the cheap option and autoroute services the dear one, sometimes by 20 cents a litre for the same fuel. LPG is patchier and country-specific: Germany and Belgium are awash with autogas pumps, France has decent coverage under the name GPL, Italy calls it GPL too, and Spain's network is growing year on year. Each region favours a different pump fitting, so carry a set of adapters (dish for France and Italy, ACME for Germany, Euronozzle for Spain) and check myLPG.eu for stations along your route before you're down to the last kilo.
What it actually costs per day
Real numbers, because the brochure version doesn't survive contact with a péage. Two people touring France on aires, driving a modest 100–150 miles every couple of days, can genuinely run on £50–80 a day including diesel, food and the odd paid stopover. Campsite-based touring with hookup pushes that up fast, and the driving days are the spikes: a long autoroute transit can burn £120 in diesel and tolls before lunch. The variable nobody budgets for is the second currency: a tour through Switzerland or into Scandinavia adds francs and kroner to the euros, and receipts in three currencies is how trip maths falls apart. That is the specific problem logging tolls and fuel in the currency you paid is there to solve, and a crossing with two boats in it goes in as one multi-leg ferry entry with a total rather than two orphaned records.
Aire at Wissant, twenty minutes from Calais, first night of a five-week loop. €8 for the night, €3 jeton for water, and a note in the log: tolls €0, because the A16 got skipped for the coast road. Five weeks later the trip report showed exactly what the tunnel-versus-ferry saving really bought: about four days of touring.
Before any of this, sort the legal kit. Beam converters, UK sticker, Crit'Air and the rest are covered in the Europe touring kit guide, and the kit itself is on the Europe kit page. The boring box behind the passenger seat is what keeps the gendarme conversation short.
