Description of the walk

Park in the church car park.

(S/E) From the car park, head away from the town hall, via Place de l'Église, and join Rue du Maréchal Foch, turning left towards the station.

(1) Cross the railway line and continue straight on towards Saint-Valery via the D111 until you reach the junction with the cycle path.

(2) At the crossroads, take the cycle path to the left (caution: shared space for cyclists and pedestrians).
At the large roundabout, cross over and continue on the cycle path on the right until you reach a dirt track about 300 m away.

(3) Take this dirt track on the right until you reach the tourist train railway line. Beautiful view of the Baie de Somme and the molières at the bottom of the bay (note: the deposits that can be seen along the dyke are brought in at high tide and are part of the "laisses de mer", a collection of natural debris and human waste transported by the sea).

(4) Turn right onto theGR®120coastal path, along the railway line, then turn left onto the dyke that goes around the Elluin marsh (a beautiful natural area rich in birdlife).
At the end of the dyke, continue to follow theGR®, turning left along the D940 road.
Turn right into the underpass beneath the road.

(5) At the tunnel exit, leave theGR® and continue straight ahead over the bridge towards the hamlet of Morlay (commune of Ponthoile).

(6) Take thefirst road on the right, then turn right again onto the D140.

(7) Just before the tourist train track, turn left onto a grassy path. Follow this path to the level crossing on the main railway line.
Caution! Abbeville-Boulogne line, no warning signals for approaching trains!
Rejoin the road, cross it and continue to the Pont le Dien fork.

(8) At the Nolette sign (hamlet of Noyelles-sur-mer), turn right onto the stony path and follow it straight ahead into this wetland area.

(9) At the entrance to Noyelles, in front of the decorated transformer, take the path along the Rio (small stream). At the junction with the tarmac road, go straight on (Rue du Riot) until you reach a barrier near the campsite.

(10) Turn left onto a grassy path and continue until you reach the back of the church.
At the road, opposite a beautiful castle, turn left and then immediately left again, in front of the town hall, to return to the car park (S/E).

The part of the route in the bay is pleasant, although there are a few sections on a road that is relatively busy in summer.

On the first part, from the moment you leave the cycle path, the hike is very good, especially the dyke section, which is the nicest part of the route.

After the dyke and up to the tunnel, there is a lot of noise from cars passing by on a main road (the major departmental road).

Then there are small, quiet roads and pleasant paths until you reach the entrance to Noyelles.
You will also probably be able to see the Baie de Somme train at some point along the route, given how close the tracks are to part of the route.

An absolutely magnificent trip through the Baie de Somme. A bit of driving, but nothing too bad as there are few vehicles.

Unpleasant sections along the roadside. Difficult to follow the GR trail at the end of the dyke. You find yourself on the edge of a very busy road when you should be able to cross the field.

The section along the sea wall and the end of the route were very pleasant, but there were too many sections along the roadside.

Start on the right at the old oak tree? Facing or with your back to the oak tree? Already off to a bad start.
No more random hiking.

A beautiful hike, especially when you're on the dyke or coastal path where we were able to watch the steam train pass by in the Baie de Somme. The start of the route on roads or cycle paths is less pleasant. The little path at the end of the route along the river in Noyelles is a lovely way to finish. We saw a group of ducks hiding there. We had good weather, not too hot, and only met two other walkers along the way. It wasn't easy to find a good picnic spot after leaving the dyke.

Nice little family route (but be careful on the tarmac sections and the railway line!).
Thanks to the poster.
