Channel Tunnel cost with a caravan or trailer in 2026

How Le Shuttle prices a car-and-caravan combination

Le Shuttle uses a supplement structure for towed combinations: you pay the standard car fare for whatever ticket tier you book, then add a fixed towed-combination supplement per leg. The supplement depends on the ticket type and the length of the towed unit, but is not itself a tiered length structure (unlike standalone motorhomes). All prices below sampled in May 2026 on leshuttle.com.

The Day Trip and Overnight £59 fare is not available with a caravan or trailer attached. The minimum-cost car-and-caravan booking is the Short Stay Saver tier at around £157 each way for an off-peak mid-week departure. Standard is the most-booked tier for caravan trips because it allows trips of any length with an open return valid for up to 12 months.

The 18m combined length rule

Le Shuttle's maximum combined length for car plus towing hitch plus caravan or trailer is 18m. This is generous: a typical UK touring combination (a 4.5m SUV plus a 7m twin-axle caravan plus 50cm hitch) is around 12m. The 18m limit is set to accommodate HGV-style trailer combinations and edge cases.

Width and height also apply: maximum 2.55m wide and 4m tall (caravan or car, whichever is the taller). These too are well beyond normal touring caravan dimensions. The width limit becomes relevant if you have wide-format awnings or externally-mounted equipment; declare the loaded width if it exceeds the bare-vehicle width.

What gets measured at the terminal

All over-height vehicles (over 1.85m) and all towed combinations are routed to a measurement lane at the Folkestone terminal. Electronic gantries check height, width and length as you drive through. If your measurements come in under your declared dimensions, no action is taken; if they come in above and push you into a higher pricing tier or breach a limit, you pay the difference at the booth before boarding.

The most common cause of over-measurement is the loaded caravan being longer than the bare-vehicle caravan length because of an A-frame storage box or rear-mounted bike rack. Always declare the loaded length, not the maker's catalogue length. A 6m Bailey caravan with an A-frame box loaded with two bikes measures around 6.5m to 6.8m, which may not change pricing tier but is worth getting right.

The platform hitch and electrics check

Before allowing boarding, Folkestone marshals visually inspect the trailer hitch, breakaway cable, and road lighting on every towed combination. Specific items checked:

• Hitch is properly engaged and the locking pin secured
• Breakaway cable is correctly looped through the towball mount and clipped on
• Brake lights and indicator lights on the caravan or trailer all functioning
• Number plate light functioning
• No visible cracks in the hitch or chassis
• Hitch lock removed (cannot reverse with the hitch lock on if needed)

If any item fails the check, marshals direct you to fix it before re-joining the boarding queue. Common failures: blown brake-light bulbs (carry spares), missing breakaway clip, incorrectly latched hitch. The check is consistent and visual, taking around 30 seconds per vehicle. There is no weighbridge and no formal hitch torque check; this is a safety walkaround, not an MOT.

Packing and loading for the crossing

The caravan is unattended on the train (you stay in or near the towing car), so loading discipline matters. Standard advice from the Caravan and Motorhome Club:

• Heavy items low and forward, near the axle
• All internal cupboards, fridge and overhead lockers secured shut
• Crockery wrapped or stowed in soft bedding to prevent breakage on the boarding ramp
• Gas valves closed at the bottle, gas appliances switched off
• Refrigerator emptied of perishables or set to gas-off / 12V mode
• Windows and roof vents fully closed and locked
• Steps retracted, awning poles stowed

The crossing is smooth (the train accelerates gently and the tunnel is essentially vibration-free), but the boarding and disembarkation ramps create a 4-degree slope that can shift unsecured items. The most common breakage is an unsecured kettle or wine bottle on a worktop sliding into a sink.

Gas cylinders, electric hookup and on-board services

LPG cylinders are permitted on Le Shuttle for caravans and motorhomes alike: up to two cylinders per vehicle (Calor 13kg or 47kg, or equivalent French Cepsa / Antargaz). Valves must be closed during the crossing. Declare LPG at the time of booking; you will receive a green LPG sticker for the windscreen.

Mains electric hookup is not available on the train. There is no 16-amp shore power on Le Shuttle carriages. Run off leisure battery for the 35 minutes if you need fridge or interior lights. For longer continental trips, ensure your battery is fully charged before boarding and avoid drawing heavy current during the crossing.

Alternatives: ferry vs Le Shuttle for caravan trips

For a caravan trip into France, Belgium or beyond, the ferry alternative is the Dover-Calais short crossing (P&O Ferries or DFDS, 90 minutes on water) or one of the western Channel routes (Newhaven-Dieppe, Portsmouth-Caen / St Malo on Brittany Ferries). Ferry fares for a car-plus-caravan are typically £150 to £300 each way on the short crossing and £250 to £450 on the western routes.

On price, Le Shuttle and Dover-Calais ferry come out roughly comparable for a caravan combination, with Le Shuttle slightly more expensive but faster. On weather reliability, Le Shuttle wins decisively; caravans are particularly affected by ferry cancellations in winter storms because rebooking with a caravan on a different sailing is harder than for a standard car. On boarding, Le Shuttle is genuinely easier with a caravan (drive on, drive off, no need to manoeuvre on tight ferry decks), although experienced caravanners cope on ferries without issue.

Insurance and breakdown cover for caravans abroad

UK caravan insurance policies (the policy on the caravan itself, separate from the towing-car policy) typically include European cover as standard for 30 to 90 days per year. Check your specific policy. If you tow regularly to France, the Caravan and Motorhome Club Mayday and Camping and Caravanning Club Red Pennant include European breakdown cover with caravan recovery as part of the membership; otherwise European caravan-specific breakdown cover from the AA or RAC runs £80 to £200 for a fortnight.

The car towing the caravan needs its own European driving insurance (usually included on UK car policies for short trips), and the caravan itself needs its own theft and damage insurance if not covered under the car policy. Many UK caravan insurers offer European cover as a tick-box at policy renewal. Confirm the cover terms before travelling.
