Hauts-de-France GR trails: Opal Coast and Via Francigena

On the Opal Coast, the GR120 links dunes, the cliffs of Cap Blanc-Nez and Cap Gris-Nez and estuaries, looking across to the English coast on a clear day.

Calais is also the starting point of the Via Francigena (GR145), which heads for Arras, Reims and Switzerland on the road to Rome.
