Near the town of Houffalize, you'll cross the river Ourthe multiple times – look for the viewpoint at the D500 road overlooking the valley. Further north, the landscape softens into the Herve region's green pastures, dotted with apple trees and half-timbered farms.

• Best season: autumn for foliage; spring for blossoming orchards

UNESCO World Heritage Sites

While the route itself doesn't include UNESCO sites directly, a short detour to Liège (15 minutes off A26) leads to the Grand Curtius museum complex (not UNESCO but notable). However, the nearby city of Luxembourg has the UNESCO-listed old town and fortifications. On this route, you'll pass within 20 km of the Major Mining Sites of Wallonia (Blegny-Mine), a UNESCO World Heritage site since 2012.

In Spa, the local speciality is the Spa cocktail (champagne, lemon, and mint) – try it at the Casino de Spa. Along the route, farm shops sell Herve cheese, the region's star product.
