Sars-le-Bois walks
Aux sources de la Canche
A long route that is ideal when the weather is less favourable.A few small roads (most of which have grass growing in the central reservation), some fairly easy country lanes and a very beautiful section leading down to Le Cauroy.
The wolf trail from Lignereuil
This hike in Artois will take you through beautiful villages between plains and woodlands on good quality paths, returning via the 1,350-metre-long Allée des Tilleuls, lined with 898 hundred-year-old trees planted in 1745 by Louis Benoit de Hamel, and Lignereuil Castle.
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 Lime Tree Avenue in Lignereuil
After starting on the Avesnes footpaths, we follow the GRP® de l'Artois, then the GR®121 for a long and varied loop.Wide paths across agricultural plains, trails along woods and finally the Allée des Tilleuls in Lignereuil.
All dotted with a few châteaux.
It's enough to make for a good day out, especially as the paths are generally in very good condition, even in wet weather.
L'ubac de Rebreuve-sur-Canche
A short, unpretentious and easy route.Very small roads and paths for a relaxing half-day out.
The three castles from Hauteville
This hike between plains and woods will take you to Barly Castle. Listed as a historic monument, it was built in 1780 by the Blin family. It is open to visitors today. You will also see Fosseux Castle, which was built in 1770 by Parisian architect Villetard at the request of Ferdinand Dubois de Hoves de Fosseux.
The Canche, the moorland and the Ravin des Cavernes
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.
The Chemin Vert in Aubigny-en-Artois
This is a reworking of an existing route, part of which has unfortunately disappeared due to lack of maintenance. The route through Aubignyen-Artois has also been modified to take the old, less busy streets, and a return trip to Villers-Châtel has been added to admire the church and castle.The circuit is done in the opposite direction to the signposting, which allows you to start with the most urban part.See practical information
Southern Lucheux circuit: La Cavée
There is very little tarmac on this route , which is best done in dry weather.Discover La Cavée, ravaged by storms a few years ago and beautifully restored.A good stretch of the route is on the old railway line (well shaded) before descending to the beautiful village of Grouches-Luchuel.
The source of the Lawe from Bajus
This hike will take you from the plains to the woods via Thieuloye and Rocourt en l'Eau, where the Lawe river has its source. Bajus was a village where French troops rested before going to the front during the First World War
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.
Trail towards Caucourt Ford
Caucourt is a small village near Olhain.From the church, you cross pleasant plains and villages, especially on sunny days.Avoid this route in very hot weather, as it is not much shade; in rain or fog, the view won't be as good!...
In the direction of the trail, you'll save the best until last, the Gué de Caucourt and its mill.
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).
Around Olhain
Long route with some fairly difficult trails.The trail between (3) and (4) is very difficult but can be avoided. It was passable at the end of September 2025 (dry period).There are a few road crossings, but with very little traffic.
Gué de Caucourt trail
Short route, on decently pathed paths, pleasant in all seasons (except in very wet weather) with a passage through the Gué de Caucourt.
April 2024 :1- The Hermin council advises against using the path between points 10 and 11 until the end of 2025. At point (9) , go straight ahead to join point (11) .
2- The track between points (11) and (12) is particularly wet. It's okay, but you'll come out a little damp. It may be preferable to go straight ahead to reach the church, then turn right to rejoin the track at point (13) .
3- Very damp but short sections before and after point (4)
