From Nemours to Montigny, following the Loing river closely.

Starting point and access: Nemours-Saint-Pierre station.
- Transilien - Line R, on the section between Paris-Lyon and Montargis.
Take the Nemours exit on platform 1, in the direction from Paris to Montargis (if arriving in the opposite direction, on platform 2, take the underground passage).

Red and white markings

(S) When you leave the station, turn right towards a crossroads. At the traffic lights, cross the D16 first, then turn left to cross the D607. Turn right, cross Rue du Général Leclerc, then take the bridge over the Canal du Loing.

Yellow markings

(1) At the end of the bridge, leave the road and go down to the left to reach the canal bank. Follow the canal on your left along a gravel path lined with majestic plane trees. Walk along the Buttes lock, cross a small road and take the footbridge opposite to cross the Loing.

Red and White + Yellow Markings

(2) At the end of the footbridge, turn left and follow the^GR®13Btowards Melun. Take the Fromonville towpath (tarmac) and walk along the Loing on your left. Note the tall silos on the opposite bank. After a barrier, the tarmac gives way to a gravel path. Pass under a road bridge and, further on, under the A6 motorway bridge. Pass another barrier, ignore a small lane on the right and continue for another hundred metres on the gravel.

Red and white + yellow + purple markings

(3) At the Fromonville lock, take the footbridge to cross the Canal du Loing. At the bottom on the other side, turn right 180°. Follow a grassy path on a narrow strip of land between the canal (on your right) and the river (on your left beyond a curtain of trees).

(4) After about 650m, at an isolated tree, turn left and enter the undergrowth. At the T-junction that immediately follows (not shown on the map), turn right. Walk along the left-hand side of the fenced gardens on the banks of the Loing. At a fork (not shown on the map; elevation 58), take the path on the right, still in the undergrowth. Ignore a^first path on the left, then a^second, and immediately cross a stream.

(5) At the fork that appears immediately, take the left-hand path. Continue straight ahead, north-north-east, ignoring a path on the left. Leave the woods and walk along a football stadium on your left.

Purple markings

(6) At the junction with a perpendicular tarmac road, turn right (ignore the^GR® trail to the left for now). At the end, cross the D40d road (take care! There is no protected crossing) and follow it to the right for about 100 metres until you reach the Étang de la Clarette car park.

Yellow markings

(7) Leave the road, cross the car park and start walking around the lake in an anti-clockwise direction. Leave the Tacots du Lac train station on your right. At the northern tip of the lake, turn sharply left. After about 300 metres, at an intersection (elevation 56), turn left to stay on the edge of the lake. This will take you back to the car park.

Purple markings

(7) Follow the D40d on the right and, after about 100 metres, cross it again (caution! no protected crossing). Follow the D40f to the football stadium.

Red and white + yellow markings

(6) Find the^GR® and follow it straight ahead. Cross the Loing on an old stone bridge and note the ruins of the Tour de Ganne on the left. At the end of the bridge, turn left onto a path (chicane). Pass at the foot of the ruined tower (information panels) then turn right onto the path. At the end, turn left towards the church. At the foot of the church's bell tower, turn right at an acute angle and you will soon reach Place Jolivet.

Red and white markings (generally sparse, absent between fields due to lack of support)

(8) Then follow the^GR®13Bto the right (note that two branches of^{the GR®13}separate here). At the crossroads, continue straight ahead into Rue Jolivet. At the end, turn left. At the next crossroads (pharmacy opposite), turn right. Go straight ahead, cross Place de la République, pass the post office and follow Rue Victor Hugo. A few metres after the stop sign, turn right into Rue des Mariniers.

(9) At the end, take the^second left, Rue Romain Renoult, and pass the war memorial on your left. At the stop sign, go straight ahead. Ignore the access to Moulin de la Fosse on your right. When the street becomes a one-way street, leave it, take a farm track on the left and pass a small shed on your right.

(10) Before reaching a large shed, turn right onto a grassy path. Head north-northeast between the fields on this poorly maintained path. At the end, turn left onto a better maintained path.

(11) At the next crossroads, turn right (north-east). As you approach a sewage treatment plant, the path gives way to tarmac. Immediately cross a small road and continue on the track opposite. As you approach a wood, ignore the^first path on the right.

(12) After about 100 metres, take the^second path on the right (be careful to spot this turn-off). Climb gently and follow the woods on your right.

(13) Shortly before the top of the hill, take a grassy path on the left (be careful here too). At the end, turn right and, at the intersection that immediately follows, turn left.

(14) At the next crossroads, go straight ahead (the purple line on the map representing the^GR®13Bis not up to date here). Walk east-north-east between the fields. At the^first house, turn right. At the intersection that immediately follows, turn left. Further on, cross Rue des Bas Cormiers on the right-hand side. At the next intersection, turn left.

(15) At the crossroads, first turn left then right to take the bridge over the railway tracks.

No signposts

At the crossroads after the bridge, take the^first right, Avenue de la Gare, which is not signposted here (leave the^GR® to follow Rue Raymond Frot, which runs parallel to it). You will soon see Montigny-sur-Loing station on your right (E).

To return home:
- Transilien - Line R, towards Melun and Paris (direct access). To return to Montargis, take the underpass or, even easier, at the crossroads (15), turn right and you will soon find the station on your left.

Train timetables: consult the Transilien website.

For motorists:
Both stations are located on the same section of the R line: park in the car park of one of the two stations and take the train to or from the other station.

Hiking boots are recommended. In wet weather, the field paths between (10) and (14) can be muddy or wet.

No water sources identified along the route. Bar and bakery near Nemours-Saint-Pierre station (S). Bar opposite the Buttes lock, shortly before (2). Pizzeria opposite Montigny-sur-Loing station (E).

Useful 1:25,000 map (at least the one accompanying this description).

Alternative route:
At the point (6), you can skip the Étang de la Clarette by turning left immediately onto the^GR®13B. This shortened version is about 3km shorter.

Hike completed by the author on¹ November 2019.

Between (1) and (4), there is a pleasant path along the Canal du Loing or the Loing.

Étang de la Clarette (7), home to many birds.

The village of Grez-sur-Loing, between (6) and (9), offers a beautiful heritage:
- Old bridge over the Loing (12th-14th century).
- Wash houses.
- Tour de Ganne (1127).
- Notre-Dame-et-Saint-Laurent Church (12th-16th century).
