Bath to Besançon Road Trip: Complete Guide

The A36 from Bath to the M4 is a sandstone-lined corridor that once carried Roman legions west. Today, it launches drivers toward the Channel Tunnel, a 50km underwater rail link that drops you into France near Calais. The full drive to Besançon spans roughly 850 km (530 miles) and takes about 9-10 hours of pure driving, not counting stops.

This route crosses three countries—England, France, and a brief flirtation with Belgium if you take the A16/E402—and passes through landscapes ranging from the Cotswold hills to the Jura mountains. Planning stops between Bath and Besançon is essential to break the journey.

Below is a quick snapshot of the journey.

From the rolling Cotswolds to the chalk cliffs of Dover, the English leg offers pastoral views. Once in France, the A16 cuts through the flat Flanders plain, but near Reims the landscape transforms into the vineyard-covered Montagne de Reims. Further south, the A5 skirts the forests of the Plateau de Langres, and the A36 winds through the Jura foothills, with limestone cliffs and pine forests.

UNESCO Sites Along the Way:

• Bath (starting point) – entire city is a UNESCO World Heritage Site for its Roman baths and Georgian architecture.
• Canterbury (detour off M20) – Canterbury Cathedral, St Augustine's Abbey, and St Martin's Church are UNESCO listed.
• Reims – Notre-Dame de Reims Cathedral, former Palace of Tau, and Abbey of Saint-Rémi are all UNESCO listed.
• Besançon (destination) – Vauban's fortifications and the citadel are UNESCO World Heritage sites.

Local Commerce & Culinary Stops: In Reims, buy local Champagne and biscuits roses de Reims. Near Dijon, stop for mustard and crème de cassis. In Besançon, try Comté cheese and saucisse de Morteau. Farmers' markets abound; the one in Besançon's Place de la Révolution is lively on Saturdays.

Road Quality: UK motorways are well-maintained but busy near London. French autoroutes are excellent, with smooth surfaces and clear signage. Speed limits: 130 km/h (80 mph) on French autoroutes in dry conditions, 110 km/h (68 mph) when wet. UK: 70 mph (112 km/h) on motorways.

Fatigue Management: Take a break every 2 hours or 200 km. The A5/A36 has numerous official rest areas. Consider an overnight stop around Reims to split the drive. Many hotels near autoroute exits offer secure parking.

Family Suitability: The journey is manageable with children if you plan stops. Channel Tunnel is exciting for kids (train under the sea!). Playgrounds at aires like Aire de Sommesous (A26) save the day.

Pet-Friendly Framework: Most French hotels accept pets (usually extra fee). Many aires have grassy areas for dogs. Channel Tunnel allows pets in the car (must keep in carrier or harness).

Hidden Off-Route Spots: If you have time, detour to the medieval village of Provins (UNESCO, 80 km south of Reims) or the source of the Seine at Source-Seine, a short detour off the A5. Also, the Château de Joux near Pontarlier (50 km from Besançon) is a stunning fort with views.

When to Drive: Spring (April-June) and autumn (September-October) offer mild weather and fewer crowds. Summer can be hot, especially in the Jura, but long daylight hours help. Winter driving requires caution; the A36 near Besançon sometimes gets snow.

Route Choice: The most direct path combines the M4, M25, and M20 to the Channel Tunnel (LeShuttle). After emerging near Calais, take the A16/E402 toward Reims, then switch to the A5 south to Dijon, and finally the A36 east to Besançon. This avoids central Paris congestion.

Tolls: French autoroutes are tolled. Expect to pay around €65-75 total for the French segments. The A16 from Calais to Reims costs about €20; the A5/A36 from Reims to Besançon about €45. Carry a credit card with chip & PIN or cash.

• Channel Tunnel: Book in advance for discounts (~£85 one-way car + passengers).
• Fuel: Petrol stations every 30-40 km on autoroutes. Diesel cheaper than petrol. Fill up in UK before crossing as French fuel can be pricier near Calais.
• Rest areas (aires) every 20-30 km with toilets, vending machines, some with playgrounds.
