Description of the walk

Park opposite the casino at 800 Boulevard du Général Sizaire. Parking is paid along the entire boulevard during the summer season.

(S/E) Cross Boulevard Sizaire to reach the pebbles and turn right: in summer, a wooden walkway is laid down to make it easier to walk on the pebbles in front of the cabins. Continue straight ahead after the last concrete groyne and you will reach the sandy area.

(1) Follow the yellow markings of the coastal path opposite, which winds its way through the shrubs in the small dunes for about 1,200 metres. At the junction with a large stony path, leave the coastal path on your left and turn right onto the wide avenue: you will see the Cayeux lighthouse.

(2) Turn left onto Avenue du Commandant Yves Masset, then right onto Avenue Parmentier a few dozen metres further on. At the crossroads, turn left onto Avenue Guillaume le Conquérant towards Brighton Woods. Stay on the avenue for 300 metres, with the Bois de Pin campsite on your left. Continue past the barrier.

(3) Take the path on the left that enters Brighton Woods. At the intersection, turn left (green marker). After 100 metres, turn right, leaving the small path that runs behind the houses. At the next crossroads, turn right and after 30 metres, turn left. At the next intersection, turn left and you will come to a clearing with benches. Take the path on your right and continue straight ahead to leave the woods and come out onto Rue Faidherbe.

(4) Follow the street to the right, passing the Les Mollières car park on your left and the campsite of the same name on your right. Turn right after the tennis court onto Rue du Camp des Anglais. Take the first left, Allée des Garennes, and continue to the end, where the path narrows. At the intersection with Rue Faidherbe, turn right and continue to the Notre-Dame Chapel.

(5) Turn left towards the ponds. Go around the pond on the right. At the crossroads, take the path that goes to the right.
After 300 metres, turn left. The path leads to the D3. Continue and after 80 metres, leave the D3 and follow the path on the left.

(6) Follow the path that runs alongside and follows the ponds on the right, then heads east at the factory before joining the D102 at Le Hourdel.

(7) Turn left to go to the lighthouse along the cycle path.

(8) At the lighthouse, you are at low tide ; otherwise, take the alternative route described in the Practical Information section. Walk down to the sand, take off your hiking boots and follow the coastline on the left to return to Cayeux. Do not venture too far if you are not familiar with the tide times, as the sea rises very quickly even if it seems far away.

(9) Pass in front of the blockhouse planted in the sand, where seals often bask on the sandbanks offshore. Continue along the foreshore. When you reach Cayeux, climb up the pebble beach at the sixth concrete groyne and rejoin the boardwalk. At the casino, return to your car (S/E).

Notes

Hike with return trip on the sandy foreshore.
Please note: Check the tide times carefully to ensure you arrive at Le Hourdel at low tide.
(8) Alternatively:
- walk along the sea on the left side of the pebble dune (watch your ankles) until you reach the blockhouse (9)
- find the large sign to the right of the lighthouse with your back to the sea, showing the local area and indicating the coastal path linking Le Hourdel to Cayeux-sur-Mer. Then take this path marked with the double colours GR® (red and white) and PR® (yellow). Join the blockhouse (9). Turn left onto the old D102 road, which is now closed to traffic on this section, and after 400 metres, turn right onto the path and then the dirt track to reach the dune overlooking the sea. Continue south. At the crossroads, continue straight ahead on the yellow coastal path orGR®120to (1) and return to the starting point.
Hiking boots.
Drinks.

Hike completed in sunny weather with strong winds. Hike completed in reverse order to take advantage of low tide. Finally, a hike where you can really enjoy the sea. At the start, a few kilometres on the beach in sand, pebbles and mud, with strong headwinds. We didn't want to take our shoes off on this long walk. Despite everything, it was very pleasant and there was hardly anyone around. We had a picnic at the blockhaus and then a welcome coffee at the lighthouse. After the lighthouse, there was a less pleasant paved section with no shade and a few ponds (factory), but there were picnic tables available at the fishing reserve (nice). The path became more pleasant again at Brighton Woods, then back to the beach, but this time on the boardwalk. However, we didn't see a single seal.

The description of the route to follow is very well done and very precise.
Except for one point when leaving the clearing with benches, where you have to take the path on the right, but there were several paths. We followed our instincts and took the widest one, and we were right.
The interesting thing about this hike is that you get to see different types of terrain: sand, undergrowth, tarmac (a little), grass, a carpet of pine needles, then back along the sea with two parallel choices depending on the tides.
There were four of us friends, and we all loved it! What's more, it was beautifully sunny for 22 September...
I will continue to use Visorando.

Hello
I did the hike again yesterday under a beautiful blue sky and very pleasant temperatures.
At the moment, there are beautiful blue viper's bugloss and lovely clusters of flowering evening primrose.
There are several paths in Brighton Wood, but it is a small wood and with the description and Visorando trail, it is easy to find your way around.
Be careful before Waypoint 5 at Mollière d'Aval, where brambles have invaded the small path. Bring a stick to clear the path, which remains passable
Between points 5 and 6, the path is blocked by the quarry, so I will modify the hike accordingly.
Enjoy your hike, everyone!

A very beautiful and varied hike in lovely weather on Easter Sunday.
We started the hike at Pointe du Hourdel so that we could be on the foreshore towards Cayeux at low tide.
Between points 5 and 6, it was impossible to follow the path along the pond, which had been badly damaged by construction machinery, so we took the small road towards the D3 and immediately turned left onto the path heading north to rejoin the route towards Le Hourdel.

Hike without much interest.
Very dangerous passage through the quarry in the middle of the machinery! Be careful with children. Risk of drowning.
Very disappointed.

Very beautiful route!
The part away from the beach was not very busy.
With the good weather, there were lots of people on the GR section.
We crossed the quarry without realising we were entering it.
We just opened and closed a gate along the way.
There will be kilos of wild blackberries to pick in the next few days on the section that runs alongside the houses!

Beautiful hike. It is important to choose the right time of day to see the seals. We did this route out of season, so I'm not sure if it would be as quiet during peak season.

Hike completed from Cayeux-sur-Mer in the opposite direction to the description, passing along the road between points 6 and 5, no problems.
Upon arrival at Le Hourdel, the surveillance service sounded the siren, indicating that the Bay of Somme had to be evacuated before the tide rose.
Seals were seen swimming in the tide flooding the bay.
Magnificent views.

It is no longer possible to follow this route as described. We tried to do it in the opposite direction. Access to the quarry area is blocked by a barrier at point 6. In any case, this area is of no interest (dirt, noise). We suggest taking a detour south via "Le Cordier". This "saves" the route, but the detour is only moderately interesting (fields) and you still have to walk a (dirty) stretch along the quarries between points 6 and 7.

Hello Bernard
There is just a round red sign with writing on it. On the other side of the road, it's the same.
Nothing else.
There was a crane (not in use) there.
Perhaps it's an extension of the quarry?
Thanks for the update.
