Bilbao to Mons: A Road Trip Through Basque Country, Pyrénées, and Belgian Ardennes

The drive from Bilbao to Mons covers roughly 1,200 km, crossing the Cantabrian Sea hinterland, the Pyrenees, the Aquitaine basin, and the rolling hills of Wallonia. The fastest route uses the A63, A10, and A2 autoroutes, taking about 11–12 hours of pure driving. But the real value lies in the detours: the Romanesque churches of the Basque Country, the medieval bastides of Gascony, and the fortress towns of the Meuse valley.

Along the way, you'll encounter six UNESCO World Heritage Sites, three major mountain passes, and dozens of Michelin-listed restaurants. This guide turns a simple transit into a curated exploration. For more on how to find the best stops and hidden gems, check this article.

Leaving Bilbao, the road hugs the green Basque hills. The first 50 km (AP-8) offer glimpses of the Bay of Biscay. As you cross the Pyrenees at the border near Hendaye, the landscape shifts to dense pine forests and mountain streams.

• Basque Country: Verdant pastures, cider houses (sagardotegiak), and surf beaches. Stop in Zarautz for a pintxo at the old port.
• Aquitaine: Flat pine forests of the Landes region, punctuated by the Arcachon Bay. Try local oysters at a roadside cabane.
• Charente and Poitou: Sunflower fields in summer, Romanesque churches. The town of Saintes has a well-preserved Roman amphitheater.
• Loire Valley: Wine estates and châteaux; the A10 runs parallel to the Cher river. Pick up a bottle of Vouvray at a cave cooperative.
• Picardy: Soft rolling hills and gothic cathedrals (Amiens, Laon). Bypass Paris via the A86 or Francilienne.

Local commerce thrives on these routes. In the Basque Country, look for fromage de brebis (sheep cheese) and fine chocolates. The Landes region is famous for Armagnac and foie gras. Wallonia offers speculoos biscuits and Trappist beers from Chimay, just 40 km off the A2.

The climate influences the aesthetics: mild and rainy in the north (green landscapes), sunny and dry in summer for the Spanish leg. Spring and autumn offer the most pleasant driving conditions with fewer tourists.

The A63 and A10 are among the safest highways in Europe, with crash barriers, SOS phones, and good lighting near toll plazas. On Spanish AP-8, some tunnels require headlights even during the day. In Belgium, the A2 is well-maintained but narrower; expect construction works. For alertness, plan a 15-minute break every two hours. Use the Aire de la Côte (km 220 on A63) for a quick nap in a rest area with picnic tables.

• Rest zones: Aire de l'Adour (A63, km 150): playground, restaurant. Aire de la Vallée de la Loire (A10, km 280): panoramic viewpoint.
• Pet-friendly: Most rest areas allow pets on leash; few have dedicated dog parks. Aire de la Garonne (A62, detour) has a dog run.
• Child amenities: McDonald's playlands at Aire de Mirambeau (A10) and Aire de Poitiers Sud. Also, the tourist office in Tours has a family room for changing tables.

Hidden off-route spots add depth. From Bordeaux, a 20-minute detour to Saint-Émilion (UNESCO) offers wine tasting. Near Tours, the medieval garden of Le Puy-Notre-Dame (1 km from A10) is a quiet picnic spot. At the Belgian border, the fortress of Charlemont (Givet) is a 30-minute loop off the A2.

UNESCO sites along the way include: Old Town of La Rhune (optional), Bordeaux's Moon Harbour, Saint-Émilion, the Loire Valley (Chenonceau), and the belfries of Mons. For more ideas on curating personal stops, refer to how to find the best stops and hidden gems between cities.

The A63 from Bilbao to the French border is a well-maintained toll highway with a speed limit of 120 km/h. The Spanish section (AP-8) costs about €7.50, while the French autoroutes (A63, A10, A2) accumulate tolls around €85 for the full journey. Fuel prices drop significantly once you cross into France.

• Tolls: Bilbao–Bordeaux €30, Bordeaux–Tours €25, Tours–Mons €30. Total approx. €85.
• Fuel: Diesel cost varies (€1.20/L in Spain, €1.35/L in France, €1.30/L in Belgium). A full tank (50L) covers 400–500 km.
• Rest stops: Aire de service every 20–30 km on French autoroutes, with free toilets, picnic areas, and often playgrounds.
• Electric charging: Tesla Superchargers at Bilbao, Bordeaux, Tours, and Brussels; Ionity stations along A10.

On the Spanish side, driving discipline is slightly more aggressive, but north of Burgos the traffic thins. The French autoroutes are cruise-friendly. In Belgium, watch for sudden speed camera traps and reduced limits in Walloon towns.

• Bilbao to Bordeaux: 3h30 via A63.
• Bordeaux to Tours: 3h15 via A10.
• Tours to Mons: 5h00 via A10 and A2.
