Stretching from the Luxembourg frontier to Cape Finisterre in Brittany, this region contains several distinct groups of summits.
Along the Belgian border lie the densely-wooded hills and steep river valleys of the Ardennes. Geologically this upland area, which extends through Belgium and Luxembourg, is a continuation of the Eifel mountain range in Germany.
 
Along the coast of the English Channel, and within easy reach of the cross-channel ports, the chalk hills in the Pas-de-Calais and Somme departments provide a duo of undemanding summits.
 
To the south of the meandering River Seine, above the bocage country of Normandy, the hills of the Suisse-Normande are dominated by the 365m summit of Mont Pinçon. Further from the coast the Normandie-Maine Natural Park includes the Mont des Avaloirs which is, at 416m, the highest summit in north-western France.
At the western extremity of the region, whilst even further west the Armorique National Parc includes irregular hills of the Monts d’Arée.  Although they are only 400m high, these hills deserve the name “monts” – the climate is cold in winter, the stony slopes are steep and it is easy to get lost if you leave the footpaths
