Exeter to Poitiers Road Trip Guide

The drive from Exeter to Poitiers spans about 370 miles (595 km) via the A30/A303 to Portsmouth, followed by the Brittany Ferries crossing to Caen (6 hours), then the A84/A28 through Normandy and Pays de la Loire. The A28 ends at Tours, from where the A10 leads south to Poitiers. A unique quirk: the A303 near Stonehenge often sees traffic slowdowns due to its proximity to the neolithic monument, adding 15-30 minutes during peak tourist seasons.

Climatic Conditions and Route Aesthetics

Best times: May-June or September for mild weather and fewer crowds. The A303 has occasional fog near Stonehenge. The A84 can be windy near the coast. Sunset views: From the ferry deck crossing the Channel, or at the Aire de la Côte de Nacre (A84) overlooking the coast.

Fuel and Route Economics

Fuel costs for a standard petrol car average £80-100 (€90-115) for the entire route. The UK section (Exeter to Portsmouth) uses petrol priced around £1.45/litre, while French motorway stations average €1.80/litre. To optimize efficiency, maintain steady speeds (60 mph/100 km/h) on the A303 and use cruise control on French toll roads (130 km/h limit). Fuel stations are abundant: every 30 miles on UK A-roads and every 20 miles on French autoroutes.

• UK leg: Fill up at Asda or Tesco near Exeter for cheaper fuel.
• French leg: Avoid motorway services; use Intermarché or Leclerc supermarkets for lower prices.
• Ferry: Fill in UK before boarding to avoid expensive French motorway prices.

Infrastructure Safety and Road Quality

• UK roads (A303): Mostly dual carriageway, well-lit near towns, but narrow sections near Stonehenge. Night driving requires caution due to wildlife (deer).
• French autoroutes (A84/A28/A10): Excellent surface, well-lit toll booths, rest areas every 20 km. Speed cameras common.
• Toll costs: Caen to Poitiers ≈ €25-30 (A84 free, A28 toll from Alençon to Tours, A10 toll from Tours to Poitiers).
