Refine your search for walks in Nœux-lès-Auxi
The Authie river, the ravine and the moor

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.
Loop to the north-west of Auxi-le-Château
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.
Loop east of Auxi-le-Château via the old railway line
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.
L'ubac de Rebreuve-sur-Canche

A short, unpretentious and easy route.Very small roads and paths for a relaxing half-day out.
De la Canche au Bois de Mortagne
Un départ pépère sur de bons chemins, puis un passage par le Sentier des Culs Trempés avant une belle remontée sur Canettemont.
The Two Woods and the Quilienne river

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).
Eps and Herbeval mountains

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!
Loop via Monflières, Bellancourt and Saint-Riquier from Abbeville
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.
Bours keep

The walk starts from the Donjon de Bours (Bours keep) and takes you up to the plateau with its remarkable views. You'll then head back down to the village, finishing with a stroll through the narrow streets of Bours.
On the ridges around Bergueneuse

More than 22 km of trails for a nature trail with some nice climbs and descents. Sharpen your calves!Beautiful views, woods and, if you're lucky, a few wild animals. At least, the ones that the hunters don't slaughter, as we recently freed two roe deer caught in snares (fox traps, but any animal can get caught there, and it's legal!).
The hills of Faux
A beautiful, undulating trail on the Ternois hillsides. Donjon de Bours (keep).
La source de la Lawe

Randonnée au départ de La Comté qui nous mène près de la source de la Lawe.
Paysage très agréable et quelques vallonnements.
The two woods and the Coqueline

A very pleasant nature trail in dry weather, but becomes more challenging in wet weather: grassy sections (a good test for your shoes, deep ruts, muddy sections).
Warning: October 2024. While it's relatively easy to get through the ruts, the last part of the path out of the wood (before point 9) is in a terrible state. The path has been broken up by machinery and you can only pass along the sides, which are themselves very difficult. It's very slippery and sometimes you have to change sides, which is a real challenge. This used to be a signposted mountain bike trail, is it still?
Trail along the little paths of Houdain via Mont de la Comté

Admittedly, the trail may seem a little monotonous, but what a beautiful path! It takes you gently up to the heights before dropping back down into the valley to climb Mont de la Comté.And at the end of the trail, the church awaits you.
