Description of the walk

Park in the car park at the town hall in Montigny-sur-Loing.

(S/E) With your back to the town hall, turn right onto Rue Raoul Jacobe. At the end, turn right and walk a few metres, cross Rue du Loing and immediately turn left to climb the stairs. At the top, turn right and climb the stairs again. Then turn left onto Rue des Champs Pérault and follow it to the end. Turn right onto Rue Orgiazzi (there is private property opposite), then take the first path on the left, Chemin des Brosses. At the bend, leave the path on the left (private), continue on the right along Chemin des Brosses and enter the forest.

(1) Turn right and follow a path to the north-east. At the T-junction (barrier opposite), follow Chemin du Tertre Blanc to the right for about 100 metres.

(2) Turn left onto a barely visible path that climbs up to the Table du Roi and a viewpoint.

(3) Turn right and descend (caution: path may be slippery in wet weather). At the bottom, turn left onto Chemin du Tertre Blanc. Cross Route de Larchant (caution: traffic) and take Rue du Croc Marin opposite. Go under the railway line and take the second street on the right, Rue Roger Genty. After about 50 metres, turn into the first street on the left.

(4) At the crossroads, turn left onto Rue Grande. Cross a street on the left and continue straight ahead.

(5) After No. 43, leave the street and take the path opposite, Sentier de Gravine, which curves to the left further on. At the end, turn right and, after 100 metres, right again onto Place Parodi. At the end, turn left and take the small tunnel under the D148 road.

(6) Cross the stream and, at the end of the bridge, first turn left then right to head east. At the T-junction, turn left. At the Plaine de Sorques car park, join the D104, cross it and take the path opposite that leads to the right of the buildings (Chemin de Montigny).

(7) At the crossroads with another path (Route du Bornage), turn right. Further on, rejoin the D104, cross it and continue straight ahead on the very straight path (still the Route du Bornage). Ignore a path on the left further on, then arrive at a T-junction. Turn left for about 30 metres.

(8) Leave Route du Bornage and turn right. The path then turns right and runs alongside the Loing on your left.

(9) After about 800 metres, you will come to a bird observatory on the right (incorrectly positioned on the 1:25,000 map). Retrace your steps.

(9) Continue along the path beside the Loing on your left.

(10) At the crossroads, go straight ahead and go around a small pond on the right.

(11) On the right, you will come to a second observatory, much larger than the first, with lots of information about the birds. Retrace your steps.

(11) Take the path on your right and turn left at the next intersection (the purple line on the 1:25,000 map is inaccurate). At the end, first turn right then left and take the small bridge you crossed on the way there.

(6) Cross the stream again via the small bridge. Turn left immediately. Do not take the tunnel, but walk past it and take the stairs on the right that lead up to the Pont de la Gravine. Turn left and cross the Loing. Shortly afterwards, take the path on the left that runs alongside the D148 (it is less dangerous). At the end, return to the road for about 150 metres.

(12) Cross the Route de Sorques and take the road opposite called "Domaine de la Vieille Écluse". Continue straight ahead and pass two small access roads to a horse riding centre on your left. Turn right at the T-junction (the main entrance to the horse riding centre is on the left).

(13) Turn left and continue almost straight ahead until you reach a campsite on your left, the Parc du Gué. Turn right onto Rue Cahen Michel. At the end, turn right and cross the Loing. At the end of the bridge, turn right.

(14) After No. 3, go up the stairs on the left. Follow the path and, at the end, turn left onto Rue du Point de Vue. At the end of this street, cross Rue du Loing and take Rue de l'Église opposite.

(15) Turn right at the second street, Rue du Tertre. Then turn right onto Rue des Corvées. Cross Ruelle des Cormiers. At the end, you will find the Montigny-sur-Loing Town Hall on your right (S/E).

We set off from Montigny-sur-Loing station. We followed the PR marked trail a little further down.
We didn't go around the Sorques plain; we went directly from point 6 to point 11.
We enjoyed walking along the Loing because, without the leaves on the trees, we could see some beautiful house facades on the other side of the riverbank.
Brambles had taken over part of the path between points 13 and 14, but it was possible to avoid them by walking along the meadow on the side.
However, it is worth climbing up and passing between points 14 and 15, as there is a beautiful view of Montigny with its church.
Ah, what a shame we didn't have time to stop at the tea room at 2 Route des Cormiers.
Thank you for this route, which we happily shortened.

It was a Sunday in July, and it was very hot. There were lots of people at the Loing river to go swimming. Nevertheless, I had a good time on this varied route and on the sections where there was no one else around. The bird observatories that I had already seen on another hike are always very pleasant. The path to the King's Table is very difficult to find, especially as there are lots of signs saying "Private property, no trespassing".

Point 2: We couldn't find the path leading to the king's table. Is it a path in private woodland?
There were lots of people at bird observatory no. 1 on Saturday afternoon.
For film buffs at Point 5, just before the tunnel, you'll have a thought for Jean Renoir.
It was a pleasant hike and the ground was dry.
Thank you for this suggestion.

Nice route, I really enjoyed the first part from Montigny (really charming) to the Table du Roi/Plaine de Sorques. Once you reach the protected site, the views from the bird observatories are magnificent, but at this time of year the path was extremely muddy, which made it difficult going. Definitely best done in drier weather!
It also seems to me that the description/information sheet for the hike could clearly indicate that it is easily accessible by public transport, as the Montigny station on the Transilien R line is just three minutes from the start of the route.

A beautiful, easy and pleasant route.
The forest section is pleasant given the heat, but watch out for mosquitoes.
Small correction at point (1): do not follow the path for a hundred metres before taking the trail on the left, but rather for about ten metres.
You can picnic at point (6), which is after point (11), a pleasant spot under the trees and beside the Loing river without too many people.
Enjoy your hike, everyone.

A very beautiful route near the Loing, with varied landscapes along the water's edge and in the forest.

The section between points 14 and 15 is not particularly interesting. You walk along property walls following a path overgrown with vegetation. It would be better to take us through the village of Montigny to discover its rural habitat.
Otherwise, it is a superb walk through meadows, woods and ponds.
Access is open along the entire route.
Don't forget your binoculars to observe the wildlife.

Hello,
Yes, the path is closed due to weather conditions and the state of the ash trees (disease). Access is therefore closed until further notice.
Kind regards

Hello
I did this hike on Saturday, 21 July.The hike started off well, but when I reached point 7 on the map, I couldn't continue to point 8 because the path was blocked by a barrier prohibiting hikers. The same was true between points 8 and 7. I retraced my steps to point 10 and then continued on the route. It was a lovely walk around the ponds. I saw a few birds and some beautiful horses.
Thank you to the author.
Kind regards

Thank you for your comments. Following likaro's suggestions, I have added a variation to the description so that this route is once again feasible. I would be grateful if future hikers could let me know what they think.

Indeed, crossing between the ponds at point 7 is prohibited. The map displayed at the car park shows that only the Sorques plain route is permitted.
We therefore continued on the 'Sorques plain and Marion des Roches' route, which starts at the Sorques plain car park, climbs into the forest and follows the same route between point 8 and the car park.
It's a pleasant walk through the forest, but the D 148 and the "Domaine de la Vieille Ecluse" road are in full sun.
At point 14, the stairs and path are barely passable (branches and brambles).

Hello
I went on this hike yesterday, 13 May. The hike started off well, but when we reached point 7 on the map, we couldn't continue to point 8 because the path was closed off by a barrier prohibiting hikers. I wanted to know if you were aware of this and if it was only temporary? We therefore took the path in the opposite direction and caught up with it later, which added 2 to 3 km to our hike.
Otherwise, enjoy your hike.

A beautiful, varied route (the narrow streets of Montigny, the forest and plain of Sorques, which are very pleasant with their autumn colours, a few birds to spot, superb residences on the banks of the Loing and numerous horses). The only downside: at point 7, the route is supposed to turn left between the two ponds, but this passage is completely fenced off and closed to pedestrians! So we went straight to the observatories at points 11 and 9 and returned by the same route. An alternative (which we realised afterwards) would be to follow a circular route around the ponds by going directly from point 6 to point 8 via the "chemin de Montigny" and "la route du bornage".
Thank you.
