Park in the small car park opposite the town hall in Oyes. The village is located about 12 kilometres north-east of Sézanne and about 15 kilometres south-east of Montmirail.
The route is not marked, even on the short section that follows theGRP®® Thibaud de Champagne (lack of support). A few posts with a yellow sign saying "Route de Oyes", indicated in the description, show the direction from place to place.
(S/E) Facing the town hall, take the street on the left.
(1) At the crossroads, take the small road on the right (yellow sign) towards Villevenard. Walk along a pond on your left and then the old Abbey of Saint-Gond on your right (rural lodges). At the end of a grove on your right, look for a post with a yellow sign inviting you to turn right.
(2) Pass the signpost and continue straight ahead on the small road. At the T-junction, turn left onto a slightly larger road.
(3) Cross the Petit Morin and then a stream overgrown with vegetation. Stop after passing a copse (with a "private property" gate on the left) and enjoy the view of the vineyards to the north.
(4) Retrace your steps to the post with the yellow sign that you came across shortly after the old Abbey of Saint-Gond.
(2) Turn left onto a grassy but well-maintained path. Walk south-southwest for about 1 km, with wet meadows or birch woods on either side. After an information sign, continue in the same direction between two cultivated plots and reach the D44 road.
(5) Cross the road (take care) and follow it to the right for a few dozen metres. Then take the first path on the left: opposite, in the distance, is the national monument to the first victory of the Marne, which is impossible to miss (except perhaps in thick fog). The path bends to the right; continue west. When you reach a small road, make a first turn left then right to rejoin a path heading west. You will reach a pond on your right (post with yellow signs).
(6) Continue west and you will come to a pond, also on your right.
(7) Continue west and you will come to a crossroads where the path begins to climb (granite marker at the edge of a field opposite on the left).
(8) Then turn right (north) towards a wood. Ignore a path on the left and walk along the edge of the wood. Make an "S" turn to cross a stream and reach the D44 road. Cross the road (take care) and climb up opposite, walking along what must have been a limestone quarry in the past on your right.
(9) At the top of the hill (beautiful viewpoint), turn right (east) onto the grassy path. At a triple fork, take the grassy path on the far left and descend to a small road. Then turn right and follow the road to the entrance of the village. At the "Stop" sign, take Rue de Saint-Prix opposite and then pass Rue des Terres Blanches.
(1) Turn right onto Rue de la Mairie and you will soon reach the starting point (S/E).
