Description of the walk

Park on Rue des Recques in Helfaut, near the water tower.

(S/E) With your back to the water tower, turn left towards a wooden barrier. This is where it all begins. Don't worry, the path is marked with red arrows throughout the walk. But be careful, at one point during the hike you will come across a yellow arrow, which in my opinion is temporary.

(1) About 300 metres after the barriers, turn left near a small building called Saint-Hubert. Continue along this path to Mont d'Helfaut, then head back down.

(2) Turn right onto Rue de Blendecques and continue for about 300 metres until you reach a dirt track opposite with aGRP® marker. Take this track, go around the huge La Coupole blockhouse, now converted into a museum, then climb up for a beautiful view.

(3) Be careful at this point: there are several paths to the right and left. Take thesecond path on the right, following the GRP® signpost.

(4) Turn right again, taking care as the markings are not very visible at this point. Continue along this path, passing ponds on your left.

(1) Continue to the left to reach the water tower car park (S/E).

A short route where you can visit the German-built dome for V1.
On the site of the former flint quarry.

A very pleasant short walk, mostly through woodland; beautiful view of the dome.
As described in the itinerary, you need to pay attention at point 3 and take the right path.
However, at point 4, we took the path marked with a yellow and red cross and luckily it was the right one.
A peaceful walk around the ponds.

Hello,

please note that we wanted to go hiking today, but by prefectural decree, it is forbidden to use the trail on Thursdays and Sundays during the hunting season.

A short but interesting route offering beautiful scenery at every turn.
However, the slopes and steps become slippery after light rain. Safety measures would be advisable.

A very pleasant, easy walk. However, be careful at the start of the hike: there is a fairly steep descent which should not be dangerous in dry weather but was when I did the walk, as it had rained recently and the ground was wet and therefore slippery.
