Berck / Le Crotoy
Le Crotoy
From the Bay of Authie to the Bay of the Somme, La Vélomaritime takes you through exceptional coastal parts. Between Fort-Mahon Plage and Quend-Plage, cycle beside the largest stretch of sand-dunes in Northern Europe. At Saint-Quentin-en-Tourmont, the Parc du Marquenterre is a fantastic protected area for bird-watching, in the heart of the Bay of the Somme Nature Reserve. The route continues to the resort of Le Crotoy, offering magnificent views of the Somme’s bay. Final stop, Le Crotoy station; here, embark on a trip along the Chemin de Fer de la Baie de Somme, aboard an old-fashioned steam train!

The route

Between Berck and Fort Mahon Plage, the cycle path runs parallel to the D940 road, although the path is broken at Groffliers (you have to cross this village on the D940 road) and between Waben and Conchil le Temple.

The link between the counties of Pas-de-Calais and the Somme can present certain difficulties. However, the construction on the county border of the Pont-à-Cailloux bridge across the Authie River should be completed by 2021. From Fort-Mahon to the Parc du Marquenterre, enjoy a track reserved for cyclists. The rest of the way, though, is on roads shared with motorized traffic, except for your arrival at Le Crotoy, where a cycle lane runs parallel to the D4 road.
