Hauts-de-France Hiking & Trekking Guide 2026

Explore the best hiking trails and trekking routes in Hauts-de-France.

Hauts-de-France has 8+ hiking trails covered in this guide, led by GR120 Coastal Path — Cap Gris-Nez to Cap Blanc-Nez, Forêt de Compiègne — Clairière de l'Armistice Loop and Réserve Naturelle du Platier d'Oye Walk. Each entry below includes the practical details — what it costs, when to go, and how to plan around it.

Hauts-de-France is northern France's dynamic region, forged from the historic provinces of Nord-Pas-de-Calais and Picardy. It is a land of soaring Gothic cathedrals, poignant WWI memorials, vibrant Flemish culture, and a rugged coastline along the Côte d'Opale. Lille, the cosmopolitan capital, anchors a region of surprising contrasts — from the underground citadels of Arras to the vast sandy beaches of Dunkirk and Boulogne-sur-Mer.
