Introduction: The M5, A38, and the Atlantic Arc
The drive from Cheltenham to Gijón covers approximately 1,100 km (680 miles) and typically takes 12-14 hours of driving time, not counting rest stops and ferries. The journey weaves through England's West Country, crosses the English Channel via ferry (Portsmouth to Santander or Plymouth to Roscoff), and then traverses northern Spain through Cantabria and Asturias.
This route is one of the most scenic in Europe, transitioning from the Cotswold hills to the rugged Picos de Europa. A key historical note: the A38 road in Devon follows the route of a Roman road that connected Exeter to Gloucester, part of the larger Fosse Way.
| Segment | Distance | Driving Time (approx) |
|---|---|---|
| Cheltenham to Portsmouth | 200 km (124 mi) | 2.5 hours |
| Ferry: Portsmouth to Santander | N/A | 24 hours |
| Santander to Gijón | 200 km (124 mi) | 2 hours |
| Alternative: Plymouth to Roscoff | N/A | 6 hours |
| Roscoff to Gijón | 700 km (435 mi) | 7-8 hours |
Road Safety, Family Stops, and Fatigue Management
UK roads are well-lit and maintained. French autoroutes are excellent, but Spanish A8 has tunnels (some unlit) and sharp bends in the Picos section. In rain, aquaplaning risk on older tarmac near Santander. Always keep headlights on in Spanish tunnels (legal requirement).
Family stops:
- Crealy Adventure Park (Exeter, UK) – Rollercoasters and animal encounters
- Futuroscope (Poitiers, France) – Futuristic 3D cinemas and rides
- Parque de la Naturaleza de Cabárceno (Cabárceno, Spain) – Safari park with bears and elephants
Pet-friendly areas: Many beaches on the Costa Verde allow dogs off-season. In France, rest areas (aires) often have designated dog zones. In Spain, pet-friendly cafes abound in Gijón's old town.
Fatigue management: Key rest zones:
- After 2 hours: M5 Sedgemoor services (UK)
- After 4 hours: Aire de la Mayenne (France, hour 3 from Roscoff)
- After 6 hours: Aire de l'Adour (near Bayonne, France)
- Arrival in Spain: Rest area at Solares (km 180 of A8) with picnic tables and lake
For hidden gems off the route, visit the abandoned village of Umbría in Asturias (5 min detour from A8 at exit 240), or the Roman bridge at Cangas de Onís (5 min detour).
Route Logistics: Roads, Tolls, and Fuel Economics
The main UK leg uses the M5 motorway (junction 10 for Cheltenham) down to Exeter, then the A38 to Plymouth, or the M27/A3 to Portsmouth for the ferry. French and Spanish highways are toll roads: from Roscoff, take the E50/A81 to Rennes, then E50-A10 to Bordeaux, then E70/A8 to Bilbao, and finally A8 to Gijón. Tolls from Roscoff to Gijón cost about €70-90 (£60-78).
- Fuel stops: On UK M5, services every 20 miles. In France, every 30 km on autoroutes. Spain's A8 has stations every 40 km.
- Fuel costs: Total approx £120-150 for the drive (petrol car, 30 mpg). Diesel cheaper in Spain.
- Efficiency tip: Use cruise control on flat sections; the Cantabrian coast has hills that can drop mpg by 10%.
The best strategy is to fill up in Andorra (if detouring) or in smaller towns off the autoroute to save 5-10 cents per litre. Credit cards widely accepted, but carry cash for rural vending machines.
Natural Landscapes and Local Commerce
This route showcases dramatic geographical shifts. Start in the gentle Cotswolds (limestone hills, sheep pastures), then the flat Somerset Levels, and the rugged Dartmoor (granite tors, wild ponies). After the ferry, northern Spain presents the Picos de Europa (limestone peaks, deep gorges) and the green valleys of Asturias.
Key natural attractions include:
- Dartmoor National Park (UK) – Hiking, prehistoric sites
- Picos de Europa National Park (Spain) – Cable car at Fuente Dé, lakes of Covadonga
- Costa Verde (Green Coast) – Cliffside views between Santander and Gijón
Local commerce: In Devon, buy clotted cream and cider. In Asturias, look for artisan cabrales cheese (blue cheese) and sidra (hard cider) poured by trained escanciadores. Roadside stalls near Cangas de Onís sell local honey and pottery.
