Spa to Tournai Road Trip: Best Stops & Hidden Gems

The drive from Spa to Tournai covers roughly 140 kilometers (87 miles) via the E42/A8 highway, typically taking 1 hour 30 minutes under normal conditions. A unique feature of this route is the sharp transition from the Ardennes foothills to the flat plains of Hainaut: you'll descend from an elevation of 260 meters in Spa to just 20 meters in Tournai, making for noticeable changes in air pressure and engine performance.

Below is a quick-reference table for the journey's key logistics:

The journey begins among the wooded hills of the Ardennes, passing near the nature reserve of Hautes Fagnes. As you cross the Meuse River at Liège, the landscape flattens into agricultural plains. West of Liège, fields of wheat and sugar beet stretch to the horizon, interrupted by small industrial pockets.

• Key viewpoint: just after exit 26 (Fexhe-le-Haut-Clocher), a climb offers a panoramic view of the Hesbaye plateau.
• Hidden orchard: at the village of Lens (5 km off A8 at exit 22), you can pick apples at Verger de Lens in season.
• UNESCO site: the Grand-Hornu mining complex (near Mons) is a 20-minute detour; a masterwork of industrial architecture.

Local commerce thrives at roadside stalls selling cheese (e.g., Herve cheese near Spa) and craft beers. For a more structured shopping, the Outlet Center at Houdeng (exit 23) offers Belgian brands. Don't miss the smoked Ardennes ham from the Boucherie du Château in Spa.

Fuel stations are abundant along the E42/A8, with major stops at Liège, Houdeng, and Mons. For diesel, expect prices around €1.60–€1.80 per liter; gasoline slightly higher. The route is mostly flat after leaving the Ardennes, so fuel efficiency averages 6-7 L/100 km for a typical compact car. Tolls: none on the E42/A8, but sections near Liège have some free-flow roads.

• Recommended gas station: Texaco at Houdeng-Goegnies (exit 23), open 24/7 with clean restrooms.
• Alternative eco-tip: Use cruise control on the long straights between Huy and Mons to save up to 10% fuel.
• EV charging: Fast chargers available at the Liège Magasin Cora and at Mons Sud rest area.

The E42/A8 is in excellent condition, with regular maintenance and good night illumination between Liège and Mons. However, watch for sudden fog patches near the Meuse valley. Speed cameras are frequent around Liège and Mons.

• Family stop: Le Parc d'Enfants de Houdeng (exit 23) has a playground and miniature train.
• Pet-friendly: the Resto du Hameau at Ghlin (exit 25) welcomes dogs and has a grassy area for walks.
• Fatigue break: the Aire de Hody (between exits 23 and 24) offers a quiet picnic area with benches for a short nap.

For hidden off-route gems, take exit 20 (Écaussinnes) and drive 5 minutes to the ruins of Château d'Écaussinnes-Lalaing, a 13th-century fortress.
