Between dunes and forest at Écault

A surprising mix of landscapes: a deceptively medieval castle, deciduous and coniferous forest then reaching the top of a dune that overlooks the beach. Most of the walk is in the shade, and the beach is ideal for a picnic.

Description of the walk

Park at the car park in the courtyard of Château d'Hardelot (depending on the route) or Rue de la Bergerie.

(S/E) From the castle car park, take the small road on the left called Rue de la Source.

(1) Find the entrance to the path on the right and go through the gate to enter the Écault forest. Leave two paths on the right.

(2) At the third, go straight ahead on the concrete path.

(3) At the crossroads, go straight ahead and pass to the right of the Chemin des Juifs stone memorial.

(4) At the fork at the entrance to Dune d'Écault, bear left. Follow the path through the dunes to the sea.

(5) Once on the beach, follow the coastline to the right for 1.3 km, until you reach the mouth of the Warenne river.

(6) Turn right and find the little path that runs alongside the river. Cross the bridge and go up to a staircase. To the right, take the GR® 121 back to the heart of the dunes.

Turn right and continue to the viewpoint.

(8) Begin a slight descent and, at the intersection of several paths not far from point 4, take the one on the left, then turn right some 50m further on. Wind through the forest, continue straight on and at the crossroads, turn left onto the Sentier de la Bécasse.

(9) At the fork in the forest, turn right onto the path that leads back to the clearing.

(2) Leave the site almost opposite on the left.

(1) Turn left onto Rue de la Bergerie to reach the car park in the château courtyard (S/E).

A beautiful walk that alternates between dunes, beach and forest. Walking through the dunes to get to the beach requires a certain amount of energy, which is rewarded when you reach the beach. After point 6, the signs warning that the usual path is closed for safety reasons are puzzling. But all you have to do is follow the path that runs alongside the road.
This was a completely peaceful walk away from the castle.
A must-do if you want to enjoy the coolness of the forest in midsummer.

A very pleasant and varied walk between sea, forest and dunes.
Easy access for young and old alike.
We walked with our dogs on a lead as we passed through the forest.
I highly recommend this walk.

A varied route, with no major difficulties except for the dunes, we returned via the beach on the wet sand and arrived just before the tide; a really beautiful walk.

Given the late arrival in the area, we set off from a car park near point 7 so that we could have a picnic on the beach (and a little nap, of course).

The route was a good mix of dunes, paths and beach. Super pleasant and enjoyable.
The part in the woods provides shade. Early in the morning, the lights must be beautiful.

A must if you're in the area.
