Easy
Departure from Arques (Pas-de-Calais) (Pas-de-Calais)
The Sentier des Fontinettes invites you to discover the often overlooked natural riches of Arques: from the Étang de Beauséjour to the Étang de Malhôve, via the Forêt de Rihoult (forest) and the canal towpath, not forgetting the nautical base and boat lift.

Moderate
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.

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).

2h 35
Easy
Departure from Gravelines (Nord)
This is a beautiful walk that highlights all the attractions of a small fortified town crossed by the River Aa, with a beautiful seafront and well-maintained green spaces ideal for walking. You will quickly forget that Gravelines is best known for its nuclear power station.

-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.

4h 50
Moderate
Departure from Ruminghem (Pas-de-Calais)
Stroll along the hedgerows surrounding the orchards, discover the Chinese cemetery and the typical farms built of yellow or red brick or stone, a reminder that we are indeed at the confluence of Flanders and Artois. Then, let yourself be haunted by the ghost of the Aa, which lurks along the waterways…
From Turkey to Fond Breton (in less than 10 km!)
5.80 mi
+358 ft
-354 ft
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.
Bois, vallée et coteau de Wavrans-sur-l'Aa
12.32 mi
+761 ft
-745 ft
6h 20
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!)
The Pihem Ravine and the Fields of Avroult
16.91 mi
+961 ft
-942 ft
7 hrs
Very difficult
Departure from Remilly-Wirquin (Pas-de-Calais)
Another long route to explore the Ravin de Pihem (the upper section of which is (temporarily?) impassable). You’ll also take 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 hike that can be split into two sections.
