Exeter to Gijón Road Trip: Atlantic Coast to Cantabrian Sea

This road trip begins in Exeter, Devon, at the foot of the River Exe, and ends in Gijón, Asturias, on the Bay of Biscay. The core driving distance is roughly 1,350 kilometres, but the journey includes a critical crossing of the English Channel—from Plymouth to Roscoff or Portsmouth to Santander, with the latter being the most direct ferry option to northern Spain. The A38 and M5 motorways take you from Exeter to the south coast, while in France, the A10, A83, and A63 are the main arteries to the Spanish border. how to find the best stops and hidden gems between cities is especially relevant here as you transition from rolling English hills to the vast plains of Aquitaine and the rugged Picos de Europa.

Fuel costs from Exeter to Gijón average around €180 (£155) for a petrol car, considering current UK and EU prices. The topography of the route—flat in France, mountainous in Spain—means fuel efficiency drops by about 10% in Asturias. Fuel stations are abundant on French autoroutes (every 30 km), but in Spain, especially after crossing into Asturias, stations can be sparse; fill up at the last service area before the Cantabrian mountains. Toll costs for the French autoroutes (A10, A83, A63) total about €70; the Spanish AP-8 toll from Irún to Gijón adds another €25. To avoid some tolls, take the N-230 through the Pyrenees, but add 1.5 hours.

• Fuel Stations: Open 24/7 on autoroutes; Spanish gas stations close 14:00-16:00 for siesta.
• Toll Payments: French tolls accept credit cards; Spanish AP tolls sometimes cash only, keep euros.
• Rest Areas: Aire de repos every 20 km in France; fewer in Spain—plan for 2-hour intervals.

The journey crosses three distinct natural regions: the Devon countryside, the flat plains of the Garonne valley, and the limestone peaks of the Picos de Europa. In Devon, look for red sandstone cliffs at Dawlish Warren. Once in France, the A10 crosses the Marais Poitevin, a marshland known as the Green Venice. The final stretch from Santander to Gijón hugs the coast, with views of the Cantabrian Sea and the Sierra de Cuera. Stop at the Mirador de la Asunción for a panoramic view of the Picos.

• UNESCO Sites: None directly on the route, but the Romanesque churches of Santillana del Mar are a 30-minute detour (Cueva de Altamira, a UNESCO World Heritage Site, nearby).
• Local Delicacies: Buy Asturian sidra (cider) from a roadside llagar in Gijón; in France, stop at a boulangerie in Niort for a canelé.
• Crafts: Hand-thrown pottery from the village of Abra, near Vitoria-Gasteiz, on the A8.

Road quality is excellent throughout: French autoroutes are smooth and well-lit; Spanish AP highways are similarly well-maintained. However, the A8 in Asturias has tunnels and sharp curves—reduce speed in rain. Night driving is safe on motorways but avoid the French N12 at night as it has unlit sections. For families, the Futuroscope near Poitiers (A10 exit 28) is a fun stop with interactive rides. The Zumaia Flysch Beach in the Basque Country is a geological wonder that kids love. Pet-friendly: most French aires have dog-walking areas; in Spain, the pet-friendly hotel Silken Ciudad Gijón offers dog beds.

• Fatigue Management: The Aire de la Groie (A11, km 70) has a quiet zone for naps. In Spain, the Area de Servicio Carreño (A8, km 425) has a truck stop with clean restrooms.
• Hidden Off-Route: The abandoned monastery of Santa María de la Escalada, off the A67 near Molledo (5-min detour).
• Safety Tip: In Spain, carry a warning triangle and hi-vis vest (mandatory).
