Park in the village square.
(S/E) From the square, turn right onto Rue de Recquigny, then right onto Rue de l’Église.
Walk round the church and turn right onto Rue d'Ostergnies. You are now on the GR® de Pays de l’Avesnois, marked in yellow on red.
(1) At the crossroads, take the small road opposite, which soon becomes a path lined with woods and pastures. Keep going straight on. In the bend a little further on, you will see the small village of Ostergnies nestled in the valley. Walk around Fort de Cerfontaine. On 2 September, the dome was destroyed. The fort nevertheless held out until the 7th. Walk down to the tarmac road.
(2) Head back up to the left towards the hamlet of Ostergnies, which became part of Colleret in 1825, and at the crossroads, leave the GR® de Pays by turning right. Walk through the peaceful hamlet, staying on the main road.
(3) 500m further on, turn left onto the ‘Chemin Romantique’ and climb through the rolling countryside.
(4) At the end of the path, turn right. You are now on the top of the plateau, where there is a
view of the village of Colleret. Turn right and, 100m further on, head down the path to the right again.
(5) At the road, turn left then right to cross the bridge. Immediately afterwards, turn left onto Rue Émile Zola. At the next junction, continue straight ahead along Rue des Écoles.
(6) At the church, turn right onto Rue Jean Dequesnes. Follow this street until you reach a chapel, then turn left. At the junction, cross the RD936 with care and continue straight ahead onto Rue Lebrun.
(7) After the level crossing, turn right onto the grassy path that runs alongside the railway line. The path becomes a small road which crosses the railway line again at the Marronniers farm.
(8) Take the small road on the right, then the first path on the left, towards Cerfontaine. Walk past the imposing Osterval farm.
(9) A detour to the right and then left takes you back to the square and the starting point (S/E).
