Bougainville walks

This 20 km circuit between Abbeville and Saint-Riquier takes you to the Monflières Chapel, then the Scardon Valley, seen from above, before returning via the Traverse du Ponthieu.

This loop allows you to discover the banks of the Authie and its marshes before leaving the valley and climbing up to the plateau. It finally skirts around the Pâture Mille Trous nature reserve. There is a beautiful view of Auxi-le-Château and its 15th-century listed church.

This hike through hills and valleys allows you to discover the three "Heritage Villages" surrounding Auxi-le-Château. It offers a variety of landscapes that testify to the inhabitants' attachment to their heritage and respect for diversity.

This walk allows you to discover the Authie valley on the east side. We pass by the old Auxi-le-Château railway station, which is a fine example of the restoration and conversion of existing heritage. Also worth noting is the small military cemetery, which reminds us of the horrors of war. Finally, enjoy the superb views of the valley and the charming town of Auxi.

This nearly roadless route takes in the wild Ravin des Cavernes and the astonishing moorland of Nœux-lès-Auxi (le Rietz). Le Rietz de Nœux is a protected nature reserve. In spring, it's home to the most beautiful orchids. Goes without saying, don't pick them! This circuit takes up a large part of the "Sentier de l'Étoile" (Path of the Star), of which there are a few routes, but no description. What's more, there are very few markings. The gates are near the fence on the right. Before tackling this route, I advise you to watch the 2 videos linked in Denis' commentary.

A lovely walk on the borders of Pas-de-Calais and the Somme.You'll discover the pretty Quilienne river (which did a lot of damage in 2016) and the Bois de Saint-Pierre (woods). It's possible to add one or two extensions, so that the trail can exceed 22km (see practical info).

This short walk of just under 6 km in and around Saint-Valery-sur-Somme is full of charm with its fishermen's streets lined with decorated and flower-filled houses, its sailors' calvary with views of the entire bay and the town, its quays along the Somme and its Saint-Valery Chapel, known as the Sailors' Chapel, not to mention its history with the Porte Jeanne d'Arc and numerous views of the Bay of Somme

A short, unpretentious and easy route.Very small roads and paths for a relaxing half-day out.

From Port du Hourdel, there is a coastal route that returns along the ponds and passes by the Maison des Oiseaux. Important note from one of our friends: please note that parking at Le Hourdel is subject to a charge, even in low season. However, the car park located between (3) and (4) was free when we went on our walk. It was therefore possible to start the walk from this new starting point.
