Exeter to Spa Road Trip Guide: Ultimate Route & Hidden Gems

The road from Exeter (England) to Spa (Belgium) spans roughly 500 miles (800 km) across three countries. The route crosses the Channel via ferry or the Channel Tunnel, then cuts through northern France and into Belgium's Ardennes. This drive is surprisingly rich in geological and cultural transitions: from Devon's red sandstone to the chalk downs of southern England, then across the flat plains of Picardy to the forested hills of the Ardennes.

The most efficient path uses the M5, A303, M3, and M20 to the Channel crossing, then A16, A26, and E42 to Spa. Expect a total driving time of about 9 hours excluding breaks and crossing. But this is not merely a highway grind – the route is punctuated with medieval towns, wartime memorials, and natural wonders.

This guide answers: how long to drive Exeter to Spa, is it worth driving Exeter to Spa, and best stops Exeter to Spa. It also dives deep into things to do between Exeter and Spa.

Highways and Roads

The journey begins on the M5 motorway from Exeter, merging onto the A303 past Stonehenge. The A303 is notorious for single-carriageway sections, but improvements have eased congestion. Near Andover, join the A34 then M3 to the M25 orbital – time this to avoid rush hour. The M20 leads directly to the Eurotunnel terminal at Folkestone. After crossing, the A16 (E402) runs from Calais to Abbeville, then the A28 (E44) to Rouen if you prefer, but sticking to the A16 and A26 (E17) towards Reims and then E42 to Spa is faster. The E42 climbs into the Ardennes, offering sweeping curves but excellent pavement.

• Motorway tolls in France: the A16/A26/E42 are mostly tolled; expect around €20 total for the French section. Cash and card accepted.
• UK leg: toll-free except for the Dartford Crossing (free if using pay-by-plate online).
• Channel crossing: Eurotunnel (£85-120) or P&O Ferries (£50-80).

Fuel and Route Economics

Fuel efficiency varies: Devon's hills reduce MPG, but flat France improves it. A typical SUV consumes 45 litres (12 US gal) for the entire drive. With UK petrol at £1.50/L and French diesel at €1.70/L, expect total fuel cost of ~£80-90. Fill up at supermarkets like Tesco in the UK and Leclerc in France for savings. Fuel stations are plentiful on all motorways, but note that French services often close 8pm-8am, so plan ahead. This route's topography – steep climbs near Exeter and the Ardennes – demands light acceleration to save fuel.

Toll and Payment Systems

French autoroutes accept credit cards, but some older booths might require chip and PIN. UK roads are toll-free except the Dartford Crossing (online payment). Eurotunnel requires booking online. Belgian roads from the border to Spa are free. Keep coins for small tolls; some French services only take cards.

Geographical Shifts

Exeter sits on the River Exe, with rolling Devon hills. The A303 cuts through the Blackdown Hills, an Area of Outstanding Natural Beauty. As you cross the border into Wiltshire, the landscape opens to chalk plains with Salisbury Plain on the right. After the Channel, the French side is flat and agricultural for 50 miles, then transitions to gentle hills near Amiens. Approaching Reims, vineyards dominate the Montagne de Reims region. Finally, the E42 ascends into the Ardennes, a forested massif with steep valleys and swift streams.

• Exeter to Blackdown Hills: red sandstone cliffs and thatched cottages.
• Picardy: endless fields of wheat and sugar beet, punctuated by war cemeteries.
• Champagne region: rolling vineyards and chalk cellars.
• Ardennes: dense beech forests, wild boars, and the famous Spa spring.

UNESCO World Heritage Sites

Two UNESCO sites lie near the route. Stonehenge is a 15-minute detour from the A303 (approx. at grid 51.1789° N, 1.8262° W). In France, the Belfries of Belgium and France (including Amiens Cathedral) are within 10 km of the A16. Amiens Cathedral, a Gothic masterpiece, is just off the A16. If you detour slightly, the historic center of Reims (Notre-Dame de Reims) is also UNESCO listed and a 10-minute deviation from the A26.

Culinary Infrastructure

UK leg: stop at the 'Hinton Charterhouse' pub near Bath (M3 junction) for a ploughman's lunch. In France, 'Le Relais d'Abbeville' on the A16 serves regional flamiche (leek pie). Near Reims, the 'Aire de Champagne' rest area offers gourmet sandwiches and local bubbly at a premium. In the Ardennes, 'La Truite Ardennaise' in Spa serves trout from local streams. For a true hidden gem, the village bakery in Ellezelles (5 min off A8) sells 'cougnous' – spiced bread with pearl sugar.

• Best roadside stop: Aire de la Baie de Somme (A16) – panoramic viewpoint and local cheese.
• Regional beverage: Champagne (Reims area) and Spa's own local beer 'Spa Sour' from Brasserie des Sources.

Local Commerce & Culture

In the UK, the 'Fleet Air Arm Museum' near Yeovilton (A303) sells model planes. French markets in Amiens (Saturday) feature macarons d'Amiens – a small almond cake. Before Spa, stop in Theux (10 min detour) for pottery and 'Pain d'Épices' (gingerbread). The Spa town itself is famous for its wooden carvings and Spa water.

Infrastructure Safety & Road Quality

UK motorways are excellent; the A303 has some narrow sections with passing lanes – watch for slow farm traffic. French autoroutes are well-maintained but some aires are dimly lit at night. Belgian E42 is in good condition, but the Ardennes curves demand caution in wet weather. All sections have emergency phones every 2 km. Toll plazas can cause sudden braking; stay alert. Night driving is safe on lit sections, but the A303 lacks lighting between Stonehenge and Willoughby Hedge.

• Key safety tip: keep headlights on in the Channel Tunnel.
• Weather: mist is common on the Blackdown Hills and Ardennes; fog lights recommended.

Family and Child Suitability

The journey offers child-friendly stops. In the UK, the 'Peppa Pig World' (Paultons Park) is a 20-min detour from the M27 (link via M3). Near Reims, the 'Futuroscope' theme park is 20 km off the A10 – ideal for older kids. In the Ardennes, the 'World of Stone' (paleontology museum) in Comblain-au-Pont is a 15-min detour. All motorway services have family rooms, but French aires often lack changing tables. The spa town itself has a funicular and a children's pool.

• Interactive museum: 'Maison de la Pierre' (stone museum) near Sprimont.
• Best picnic spot: 'Signal de Botrange' (highest point in Belgium) with playground.

Pet-Friendly Framework

Animals are welcome on the Channel Tunnel (in vehicle, no walk in the terminal) but require a pet passport. French and Belgian motorway services allow dogs on leashes; some have designated pet areas. In the UK, many country parks off the A303 (e.g., Stourhead) are dog-friendly. In Spa, the 'Pouhon Pierre le Grand' spring allows leashed dogs outside. Pet-friendly cafes like 'Café des Sources' in Spa provide water bowls.

Fatigue Management & Rest Zones

Plan breaks every 2 hours. In the UK, the 'A303 Truckstop' near Amesbury is open 24/7 and offers cheap coffee. In France, 'Aire de la Canche' (A16) has a quiet room and showers. For a nap, 'Aire de l'Authie' (A16) has shaded parking under trees. The Belgian 'Baraque Michel' rest area (E42) has a panoramic view and benches. If exhaustion hits, the hotel 'Le Manoir de la Forêt' in Malmedy (5 min off E42) offers hourly day rooms.

• Best nap spot: 'Aire de Champagne' (A26) – quiet, well lit, with 24h security.
• Rest stop tip: set a 20-minute timer to avoid oversleeping.

Hidden Off-Route Spots

Five-minute detours reveal gems: near Stonehenge, the 'Cuckoo Stone' (a fallen sarsen) in a field. In France, the abandoned 'Château de la Bove' near the A16 (Les Boves) is a network of underground chalk quarries. Between Reims and Spa, the 'Waterfall of Coo' is a 5-min detour off the E42 – a 15-meter cascade in a theme park. Also, the 'Grotte de l'Abîme' near Rochefort (10 min off E42) is a cave with prehistoric paintings.
