Mareuil-Caubert 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 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

If you want to go for a walk with the option of a dip in the sea halfway along the route, this is just what you need!

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.

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 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.

Walk in the heart of Le Hâble d'Ault, where it is advisable to bring a pair of binoculars to observe the birds.

This hike, which is not particularly difficult, allows you to discover the cliffs of Ault and Onival beach to the north from the panoramic view of the Bois de Cise. Moderator's warning: Report of restricted access (January 2021) following a landslide on the cliff.

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 to discover the beautiful villas of Mers-les-Bains. Pass through the marshes before discovering Eu and its castle. A beautiful climb to the Chapelle Saint-Laurent to discover the Bois de Cise. Please note that the return route along the cliffs following thePR® trail, which offers beautiful views of the coast, is closed by municipal decree following recent cliff collapses. By keeping well to the left of the path, it is still possible to enjoy the views.

A short walk when you don't have time to go too far.

In the Riez de Nœux-les-Auxi, there is a beautiful walk along the Canche in Boubers and Ligny. With the climb up the Ravin des Cavernes, you really feel like you are in another world (even more so now, with the final chaos). The route becomes very difficult in wet weather in the Riez and the ravine.

A feeling of the beginning of the world on this immense beach on the Opal Coast.Get there by bus, then on foot via the GR®120. A real treat.

A bucolic hike along the pure, fish-filled waters of the Canche, starting at La Citadelle, whose Royal Castle dates back to the 13th century. You'll start by walking along the ramparts. You'll pass through the marshes and stroll along the banks of La Canche. You may come across fishermen or sportsmen training at the Canoe-Kayak club.

The old marked trail around Ambricourt is unfortunately poorly maintained or not maintained at all. We have been walking it for 25 years and have encountered difficulties every time (poor signage, paths buried under nettles or difficult to walk on).The start at Teneur allows you to pass (twice) in front of the superb limestone hillside of Teneur. Deer are often visible in or around the Bois de Crépy The path is in very poor condition between points (2) and (6). If possible, avoid the period between mid-June and mid-August. The passage after point (3) will be easier if the field is not too far into the growing season or has already been harvested.

A short but very hilly route (carto-explorer even gives 230m elevation gain) around the village of Eps, unjustly excluded by the marked trails. Beautiful views.Best done on a sunny day - it's magical!
