Brighton to Blois Road Trip: Essential Guide

The A27 from Brighton leads westward, merging onto the M27 to Portsmouth for the cross-Channel ferry. This route covers approximately 480 miles (772 km) and takes about 8–9 hours of driving, excluding the Channel crossing. The undulating chalk downs of Sussex give way to the flatlands of northern France, where the A16 becomes the primary artery toward Paris. The final leg on the A10 and D952 delivers you into Blois, a historic town on the Loire River. Notably, the ferry from Portsmouth to Caen (or Le Havre) offers a direct path through Normandy, bypassing Paris traffic—a common local trick. For those pondering “how long to drive Brighton to Blois”, plan for a full day with stops.

From Brighton’s chalk cliffs, the road descends through the South Downs National Park—visible from the A27. After the ferry, the Norman countryside unfolds with pastureland, apple orchards, and half-timbered villages. The A13 crosses the Seine at Rouen, offering a glimpse of the cathedral. South of Paris, the Beauce plain stretches flat and fertile, with vast wheat fields contrasting the Loire’s wooded valleys. Locals sell honey and goat cheese at roadside stands near Blois.

• Natural highlights: Seven Sisters cliffs (Brighton), Seine valley at Rouen, Loire banks

The route passes two UNESCO sites: the Banks of the Seine (Paris) and the Loire Valley between Sully-sur-Loire and Chalonnes. The Loire Valley, a Cultural Landscape, features Renaissance châteaux like Blois and Chambord. For hidden gems, the village of Beaugency (Loiret) boasts a Romanesque church and medieval bridge.

The A27 and M27 provide smooth motorway driving to Portsmouth. In France, the A13 from Caen to Paris (toll road) offers excellent surface quality, with service areas every 30–40 km. After Rouen, the A154 and A10 connect to Orléans, then the D952 follows the Loire to Blois. Fuel costs average €1.80–€1.90 per litre (diesel) in France; a petrol station concentration exists near motorway junctions. For optimal fuel economy, fill up before entering toll sections, as motorway stations often have higher prices. The Channel crossing adds ~€60–€90 for a standard car (round trip). Total road tolls: around €25 (A13/A10). Electronic toll tags (e.g., Liber-t) speed passage. Parking in Blois is available at Parking du Château (€1.50/hour).

Speed limits: 70 mph (UK), 130 km/h (French motorways, reduced to 110 km/h when raining). Seat belts mandatory; child seats required for under-10s. French police conduct random checks; carry reflective vests and warning triangle. The French A13 motorway is well-lit but can be heavy near Paris (avoid 17:00–19:00). Fatigue breaks: plan a stop every 2 hours. Recommended kid-friendly stops include Parc Astérix (exit 8 near Paris) and Loire Valley nature reserves. Pets: rest areas with dog walks exist; many hotels accept pets (check ahead). The route has good mobile coverage; last fuel stop before Blois is at Aire de Blois (D956).
