A beautiful route around Lucheux, best done in dry weather, as theGR®124is in very poor condition (and poorly marked!) in the forest.

This is a long route on good paths, which means it can be enjoyed in all seasons.There are a few sections on roads, but apart from the D68 near Avesnes, they are not very busy.The icing on the cake is the crossing of Avesnes-le-Comte via Les Voyettes.

The Beech Tree Route in Lucheux
14.25 mi
+748 ft
-745 ft
6h 50
Difficult
Departure from Lucheux (Somme)
I have tried to revive an old marked trail (and kept its name) which, like many in the area, has completely disappeared (the Somme CDRP seems rather ineffective and, moreover, is unreachable).
It is a route with virtually no roads, but crossing the Forest of Lucheux is very difficult as many of the paths are badly damaged. Fortunately, the GR® markings are clear there.
So, a difficult route, even very difficult after rain: in good condition on 19 April 2026, apart of course from the section through the forest where the ‘path’ is in a terrible state.

Starting from Saint-Pol-sur-Ternoise, the Fossé Cagnu route takes you along a few of the town’s narrow lanes, then along paths that are sometimes damp, followed by a short detour through the village of Troisvaux before descending the famous ditch.
Along the way, it’s not uncommon to spot a few deer.

Departure from Ligny-sur-Canche (Pas-de-Calais)
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.

Departure from Aubigny-en-Artois (Pas-de-Calais)
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

A beautiful route starting from Brias with its church and castle towards the Moulin Blanc plain, the village of Valhuon and the Bois d'Antigneul, where it is not uncommon to encounter a few deer. This route is marked in yellow for the most part and is fairly easy to follow and without difficulty.

A long hike in the north of the Somme. Most of the paths are in good condition (even in late winter) and there are occasional tarmac sections, but no traffic.

Moderate
Departure from Caucourt (Pas-de-Calais)
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.

Moderate
Departure from Gauchin-Légal (Pas-de-Calais)
A short route, on paths that are more or less paved, pleasant in all seasons (except during very wet periods) with a passage at the Gué de Caucourt.
1- Hermin Town Hall advises against using the path between points (11) and (12) until the end of 2025. It is now April 2026 and nothing has changed: no works are underway and there are barriers on both sides. I have just walked along it and it is perfectly passable, though still treacherous.

From the car park, you’ll find yourself facing Olhain Castle, one of the most beautiful in the region. The rest of the walk alternates between stunning views and short stretches through the undergrowth (not too dense) before reaching the ‘esplanade’ of Olhain Park. You’ll find yourself facing an exceptional panorama.
If you’re lucky, you might see paragliders taking off (admittedly, this is quite rare), and why not visit during the hot-air balloon festival to watch these huge, colourful balloons take off right before your eyes.
