Difficult
Departure from Fauquembergues (Pas-de-Calais)
It's a route that will delight altitude enthusiasts (Carto exploreur and the Visorando app suggest it's as high as 500m). What's more, the views are stunning.
Route slightly modified in November 2019.
All trails are very good as of May 14, 2020 (even if some are very grassy).

-1,030 ft
8h 15
Difficult
Departure from Wismes (Pas-de-Calais)
A long route with very little tarmac and a superb climb.
There are also a few long straight stretches through the fields that will delight many!
Late July 2020:
- the section between points 6 and 7 is in excellent condition.
- at point 13, after the copse, you cross a maize field for about fifty metres (the path is clearly marked) before finding the track.

Difficult
Departure from Remilly-Wirquin (Pas-de-Calais)
Another route around the Coteau d’Elnes with very little tarmac. Crossing the Bois d’Esquerdes is even more enjoyable, and the long walk along the riverbank is most pleasant. Finally, the section through the hillside, especially in fine weather, is a real delight (even if it is a bit of a struggle!)

Very difficult
Departure from Remilly-Wirquin (Pas-de-Calais)
Another long route to explore the Ravin de Pihem (the path has been remarkably well maintained: it’s superb in early August 2026). You’ll also follow a superb path at a place called ‘Les Champs d’Avroult’ before popping over to have a look at the old quarries at Cléty.
An easy walk that can be split into two sections.

3h 00
Moderate
Departure from Renty (Pas-de-Calais)
A short but fairly strenuous route with a steep hill and some very grassy paths.
On 12/08/2025: the start of the trail is once again very overgrown (brambles and nettles). It's passable but it's best to wear trousers or good gaiters and, of course, bring a walking stick or even a pair of secateurs.

Difficult
Departure from Reclinghem (Pas-de-Calais)
Three lovely climbs and a long stroll across the plateau make for a walk surrounded by nature. A very hilly first section, followed by a long stretch along the heights before descending to Reclinghem with magnificent views. The icing on the cake is an optional circular loop I suggest, which brings the total elevation gain to over 300 m.

6h 50
Difficult
Departure from Nielles-lès-Bléquin (Pas-de-Calais)
Nothing spectacular, but a good day out in the fresh air. It’s best to go during dry spells, as some paths can become quite (or even very) difficult.
You could also consider starting from Wismes (car park by the church), which allows you to leave your picnic in the car and thus take some of the strain off your back.

5h 55
Moderate
Departure from Verchocq (Pas-de-Calais)
Exploring the Vallon de Beaussart and passing close to the Bois de Renty, always in the hope of spotting some wildlife: on 16 October, there were only a few pheasants, but they practically let you stroke them. A real treat for hunters!
There are practically no roads on this route.

Departure from Esquerdes (Pas-de-Calais)
The Wavrans-sur-l'Aa nature reserve consists of two hillsides separated by a dry valley, Mont Carrière and Montagne d'Elnes. The chalky slopes of the reserve are steep and unusual for the region. They were also "sculpted" by the bombs of the Second World War.
