There is a very pleasant picnic table at point 6 (football pitch).

Description of the walk

Park in the Cadran car park on the D951.

(S/E) From the car park, walk under the trees to join the Route Forestière du Cadran, which runs behind it, and turn left.

(1) At the first junction, turn right (unpaved track). Stay on this track until you reach the hamlet of Les Haies (Germaine railway station).

(2) When you reach the first houses, turn left. The small road is tarmacked at first, then becomes a gravel track. It follows the railway line at a distance as it heads north.

(3) You’ll come to a junction with the^GR®®142. Do not continue straight on towards Rilly-la-Montagne; turn left towards Villers-Allerand, then 100 metres further on, turn right.
Take a grassy path towards Villers-Allerand. There’s a steep descent along a path, which is often slippery, running alongside the vineyards.

(4) From Villers-Allerand, follow Rue Alphonse Hanin, then turn left onto Rue du Voisin and follow the^GR®®142signs.

The^GR®® crosses the village, leaves the road to the right between high walls (Chemin de la Petite Barbarie), and passes by the football pitch (picnic table).

(5) Walk through the vineyards to the D951. Cross the county road at the nearby pedestrian crossing. Take the^GR®® opposite, walk through the vineyards and, at the Fork in the road, turn right. Enter an area of fields and continue straight on to the football pitch.

(6) Turn left. Walk to the village of Sermiers. Follow the^GR®® to the top of Sermiers, through the vineyards.

(7) Where the^GR®® turns sharply to the right, leave it and continue straight on. The path climbs between the vineyards and the woods to the Route Forestière de la Noëlle.

(8) At the crossroads, turn right, then left at the next junction. Follow the gravel forest track which crosses the woods heading south (Route de la Fontaine à l’Aulne).

(9) At the junction with the Route Forestière de la Mer Rouge, follow it to the left to return to the Cadran car park on the D951 (A/D). Take care when crossing the D951, especially during the week.

A beautiful hike completed in July 2025 with a 2-year-old child on my back in 4.5 hours.
No particular difficulties except for a fallen tree that we had to crawl under with our little one on our backs, which she found very funny!

A beautiful mix of forest, vineyards, villages and views.

Hike redone today. It is indeed feasible in autumn or winter, as there is very little mud.

Very nice picnic table in full sun next to the football pitch in Sermiers. The gate is closed, but there is a small entrance on the side.

A very beautiful route, pleasantly varied between forests, vineyards, villages and viewpoints. Good signage overall, except perhaps at the exit from Sermiers, which could be improved.

Thank you for this advice.

During the next lockdown, in order to be able to go wherever you want, you will need to equip yourself with a rifle.

A very pleasant hike, undertaken in beautiful late autumn/early winter weather; the only downside was that we had to change the end of the route, which was a hunting area.

We did this hike in very hot weather. It would have been better to start at the Villers Allerand football pitch and head towards Sermiers before the heat became too intense.

Thank you for your feedback, I have made the change.

I have also added the Montchenot baker and caterer, who has just set up shop near point 5.

We did this hike from Rilly la Montagne station, starting at point 3.
The weather was ideal, with blue skies, sunshine and a light breeze. The scenery was superb.
However, there is little shade on the route, which must be more difficult in hot weather.
Just one comment: in Villers Allerand, the street that runs past the football pitch is called Rue de la Petite Barbarie, not Rue de la Ferme. Just follow the GR markings.

Hike repeated today in the opposite direction. Despite the rain, there are no muddy spots. So it's a "four-season" route.

However, there is no longer a pedestrian crossing in Montchenot. That's a shame.

A beautiful hike thanks to the diversity of the landscapes: forest, vineyards, plateaus.
The view of Reims as you arrive in Sermiers is superb. We did this hike in beautiful weather but it was very cold (-1°C). The section of the GR between Sermiers and Villers Allerand was very windy. In summer it must be quite hot because it is exposed, so bring a cap; today a hat was essential.
Although quite long, there are no difficulties, although there may be some muddy patches in wet weather and a few ruts.
My husband likes small paths, and I like wide "white" paths: this hike is perfect for both of us
. The map and GPS track are perfect for finding your way around, so we didn't use the description.
We didn't start from the Cadran car park but from Les Haies and parked the car just around the corner to the right before the barrier that runs along the forest.
Thanks to the hiker who suggested this lovely Champagne trail to us.

Hello,
I personally experienced a minor technical problem when arriving in Saint Imoges. I couldn't find the village on the Visorando map I had downloaded, so I changed the route until I reached a point I could find on the map (in fact, we ended up doing a circular route around Sermiers). I don't use the description much in general; I mainly use the map and the markers to find my way. It's a beautiful hike, with a significant portion in the forest and a magnificent view of vineyards and villages when you leave the forest at Sermiers.

I'll add a few more details to my description... I don't want anyone to get lost on one of my routes. I'll pretend there are no markers, instead of relying on the GR.

Actually, where you entered the vineyards on the left, you should have gone slightly to the right, away from the vineyards.

If you go back in a fortnight, it will be the middle of the grape harvest.

Hello,

after crossing Montchenot, the GR crosses the vineyards, then follows the bottom of the vineyards, then crosses the fields. You stay more or less in the same direction until you reach the football field, where you turn left towards the village.

In this area, where the GR markers are sometimes difficult to see, I think it is essential to use the map or smartphone app.

I think you must have left the GR to the left, into the vineyards. As a general rule, when you think you are on a GR and you can no longer see the markers, it means you are no longer on it.

Hike done today, problem encountered after crossing the main road at Montchenot: the GR trail is poorly marked in the vineyards. I got lost at the top of the vineyards and turned left (no markings) and ended up on the D 26 towards Sermiers. It's not ideal to take the road, but I couldn't find the path through the vineyards. Instead of turning left, should I have turned right and gone downhill? Thank you if anyone knows, so that I can do it again... otherwise, it's very good.
