Description of the walk

Departure from the church in Eth.

(S/E) Descend towards the castle built in 1766 (private property) via Rue du Château. At the gate, turn right onto Chemin de Saint-Hubert. Pass in front of a chapel dedicated to this saint. Legend has it that Saint Hubert, who became a hermit, cured rabies with a golden key given to him by Saint Peter.

(1) When you reach Le Sart, a tributary of the Aunelle, turn left (do not cross the bridge) and follow the stream. 200 metres further on, you will come to a rest area, a fountain and a drinking trough. Climb up to the road and continue to the left (take care) to reach an octagonal chapel, the Chapelle Notre-Dame des Enfants. In the past, mothers would come here on Good Friday to have their children take their first steps.

(2) Follow the Chemin des Boers, an old paved road, opposite. At the end, at the T-junction, turn left and at the next intersection, turn right. Behind you is a field that was used in 1942 for parachuting illegal immigrants, code name "Pô". 400 metres further on, you will cross the border.

(3) At the crossroads, turn left onto the gravel path (Rue de la Marlière) and, after 100 metres, turn right onto the grassy path to the ford. Continue straight ahead.

(4) Further on, cross the Angreau-Roisin road (N553) with caution, then continue downhill
to the car park of the Verhaeren Nature Centre Museum.

(5) You will walk through the listed site of Caillou-qui-Bique in the Hauts Pays nature park. In spring, the undergrowth is carpeted with daffodils and narcissi.
Pick the flowers... with your eyes. Please respect the site regulations. To the left of the Émile Verhaeren memorial, follow the path down to the Honnelle, which you can cross via a footbridge.

(6) Take the path on the right which, at the foot of the embankment, follows the meandering course of the river and passes at the foot of the "Caillou qui Bique".

(7) The rock dates from the Middle Devonian, the fourth period of the Palaeozoic era. It was a prehistoric site later occupied by the Romans.
After the two cafés, turn right towards the ford. Between the rock and the ford, note the remains of old marble quarries on the left. Cross the ford on the right via a footbridge and continue for about 150 metres.

(8) Turn right and follow the tarmac road straight ahead to Roisin (mind the traffic).

(9) At the entrance to the town, follow Rue du Berceau on the left, then turn right twice along the castle walls. At the church, with its tower dating from 1734 and buildings from 1842, turn right onto the square. Then turn left onto Rue Eugène Prévost.

(10) Turn left towards Eth and Bry (Rue Bourdon) and continue for 500 metres until you reach the old customs post at a place called "la Marlière".

(11) Continue along a gravel path (Chemin de Roisin) to enter Eth.

(12) Go straight ahead and take Rue de la Mairie and Rue du Curé after the roundabout to reach the church (S/E).

Worth a visit

(S/E) Eth Church:
The ogival-style church with a Romanesque portal was built of stone and brick. Inside, some of the stone pillars date from the 12th century.

(9) Roisin Church: Inside the church are recumbent statues and the mausoleum of the Baudry de Roisin family. Legend has it that when Dagobert ruled Austrasia, a priest named Ghislain, who came from Athens, settled
in the desolate part of the Hayne valley to evangelise the poor.
Summoned to Cambrai by Bishop Saint Aubert, Ghislain stopped at the home of the Lord of Roisin, whose wife had only difficult births. He began to pray, placed his baldric on the belly of the expectant mother, and the child was born easily. He was named Baudry because of the baldric. The lord gave Ghislain (who had become a saint) 60 bonniers of land, and all the eldest sons of this family were called Baudry.

We went in January, so it wasn't very busy, but we did meet a few hikers who were enjoying the beautiful sunny day. We really enjoyed the hike, because what a surprise to find this rock jutting out along the Honnelle River – what a change of scenery! And it's only a few kilometres from Valenciennes. We didn't know about it, even though we live in the area. It's great, and we'll definitely do it again, especially if we have a very hot summer..

Beautiful border hike. No difficulty, varied route. Please note that the rock that sticks out is not indicated by a sign and is located on the left a few metres before the point.
The weather was magnificent! Worth doing again.

A very beautiful hike, although the forest section is a little busier. The café at Caillou qui Bique is very pleasant!

A lovely walk that alternates between flat terrain and wooded areas
Due to construction work, the trail starting at the Sart stream was closed.
Halfway through the hike, don't miss a stop at the Café du Garde au Caillou, which is very popular.
The new owners are very welcoming. (light refreshments available)

A bit long, though. It would be good to add an alternative to make the route shorter for some people.

A very beautiful place steeped in history. It's a shame that the poet's museum is closed and that you have to make an appointment to visit it.
The village of Eth has some beautiful properties and a superbly renovated castle.
