The Amasse valley

Discover the Ambroise river, the Amasse, a small tributary of the Loire which flows into the river here and which was developed from 1856 onwards to prevent flooding in the town during heavy rains.

Description of the walk

On the Île d'Amboise, park near the Île d'Or campsite.

Please note! This route is not signposted as such

(S/E). Head to the south side of the island along the Loire, near the statue honouring Leonardo da Vinci. Take the small path west to get back on the road. Continue west on the road to the foot of the Pont du Maréchal Leclerc bridge, then turn right to take the stairs and climb up to the road.

(1) Continue to the left to cross the southern arm of the Loire. At the end of the bridge, cross the slip road, then go down the stairs opposite and cross the Quai du Général de Gaulle. Continue to the right, take the first street on the left and you will arrive at Place Michel Debré.

(2) Continue straight ahead, leaving the access ramp to the château on your left. Further on, look for the red and whiteGR®®3markings and follow them, continuing straight ahead along Rue Victor Hugo to the Château du Clos Lucé.

(3) Leave theGR®® trail, walk past the château entrance and turn right down Rue du Clos Lucé, which runs alongside the estate to the bridge over the Amasse, for a first glimpse of this small river that is the common thread of this route. From the bridge, retrace your steps a few metres and turn right onto Allée du Pont Moulin. Continue straight ahead until you reach the entrance to Château Gaillard (whose gardens are open to the public in summer).

(4) At this point, note the various structures built on the river to divert excess water, if necessary, to the tunnel dug into the rock a few metres north of the street. Then return along the same path to Clos Lucé.

(3) Turn right onto Rue de la Malonnière, back onto theGR®® trail. Continue straight ahead until you reach Chemin des Breussolières, C.R.64, on your right.

(5) Leave theGR®® again to take this path. Continue straight ahead on this path, which further on crosses the hamlet and leads to a road.

(6) Walk a few metres to the right to take a look at the Amasse, then turn back.

(6) Continue straight ahead on Rue de la Côte Chaude. Keep going along this small road which runs alongside Amasse on your right.

(7) Pass in front of a beautiful property, the Moulin d'Olivet. Continue straight ahead, still on Rue de la Côte Chaude, until you reach Boulevard Saint-Denis Hors.

(8) Turn right to cross this busy boulevard (be careful! There are no pedestrian crossings). Continue along the small road opposite and cross the Amasse on a bridge. Further on, you will come to a road.

(9) Turn left, staying on the hard shoulder, then turn onto the first road on the left. Pass in front of the Château des Arpentis estate and cross the Amasse again.

(10) Further on, turn right onto Route de Saint-Lubin. Continue along this small road which enters the woods and runs alongside the Amasse.

(11) Pass close to a large pond in Saint-Lubin, then close to small ponds on the Amasse. At the intersection, continue right towards the entrance to Saint-Règle until you reach the bridge over the Amasse and the picnic area, for a last look at the "wild" Amasse.

(12) Turn back and, at the fork, continue right on the small road that crosses the woods.

(13) When you come out of the woods, turn left onto the path and follow theGR®®3trail again, which is also theGR®®655East trail to Santiago de Compostela. Continue straight ahead on this path, first between woods and fields, then between fields and an industrial estate.

(14) Cross the road (be careful! There are still no pedestrian crossings) and continue straight ahead. You will eventually come to a crossroads. Continue straight ahead and you will soon see the Chemin des Breussolières on your left, which you took on the way there.

(5) Continue straight ahead and then turn right onto Rue du Vallum (signposted Rempart gaulois, Butte de César). At the end of this street, note the remains of the Gallic rampart on your right, then continue left onto Rue Augustin Thierry. Note the tumulus, Butte de César, in a field on your right. Ignore the next street on your right and continue straight ahead.

(15) Take the second street, Rue des Chateliers (dead end, sign for Maison des Pages, Loire). At the end of this street, take the alleyway that winds down towards the Loire between the houses. Pass in front of the Maison des Pages. Further down, continue to the right on Rue du Rocher des Violettes (sign for Tunnel de l'Amasse) and you will arrive at the Tunnel de l'Amasse. It is through this tunnel that, during periods of high water and to protect the town centre of Amboise, the water from the Amasse is diverted to the Loire from Château Gaillard. Turn left and walk along this building to reach Quai Charles Guinot.

(16) Cross (carefully!) then turn left and walk along the Loire on your right.

(17) At the "Le Manoir des Minimes" hotel, cross the road again and take Rue Louis XI opposite, then turn right onto Rue de la Concorde to walk along the Château d'Amboise fortress below. You will come out onto Place Michel Debré opposite Rue Nationale, Amboise's main shopping street.

(2) Turn right to return to the quay and the bridge and come back to the Île d'Or campsite (S/E) via the same route you took on the way there.

Notes

I do not recommend this hike in winter: the section between (13) and (15) is long and rather monotonous, as theGR®®3is not particularly well marked in this area. In winter, the bare fields accentuate the monotony. Furthermore, Château-Gaillard is closed in winter.
Otherwise, there are no particular difficulties on this hike, which follows wide paths or small roads.
Shopping is possible (and even recommended!) in the town centre.

Possible alternative route suggested by a Visorandonneur:
Modifications to the route between (2) and (6) to avoid tarmac, follow the Amasse even more closely and discover Château Gaillard without having to make a return trip.
Go to the car park near the castle (cross and follow the Amasse). At the end of this car park, a path leads to the Clos Lucé. Continue to the entrance of Château Gaillard, then cross the Amasse and a housing estate to reach Avenue Léonard de Vinci. At the roundabout, a recent path runs alongside the Amasse to (6).

The Amasse river. Protected from flooding by the Loire by dykes, the town of Amboise also has to contend with a small river, the Amasse, which runs underground through the town. To get around this problem, major works were carried out in the 19th century. If the river floods, a dam prevents the Amasse from following its natural course and diverts it into a 700-metre-long tunnel dug into the hillside upstream of the town. This tunnel opens out onto the banks of the Loire, allowing the Amasse to join the river via another route, without passing through the centre of Amboise, thereby reducing the risk of flooding. In 1856, disaster could not be averted and the streets were flooded with up to 2 metres of water!

Château Gaillard, the Royal Castle of Amboise and the Clos Lucé, home of Leonardo da Vinci.

A lovely hike for the 38 hikers. Very pleasant surroundings. We encountered few hikers and a few walkers.
We used a GPS track to complete the route.

There were five of us on the route and we really enjoyed it – we just didn't like crossing the main roads. We liked the GR 3 trail, with its little paths lined with trees – it was really pleasant.
You can do this walk and then visit the Clos Lucé or the château or Château Gaillard. On the way back, stop in Amboise for a drink.

Thank you.

Very good description. As already mentioned in previous comments, it's true that the return journey from point 13 is not particularly interesting.
I wanted to shorten the hike by going from point 10 to point 14, i.e. without turning right onto the Saint-Lubin road, but then I got a little lost...
You can see some very pretty houses, many of them cave dwellings, very few people, which is nice, and little pockets of nature. It was quite good!

If I had read the comments before setting off, I would have opted for the path along the Amasse, which is undoubtedly more suited to hiking than a tarmac route (although the scenery was pleasant).
The straight section of the GR between 13 and 5 is uninteresting (between fields and industrial estates).
It's true that this is part of the Way of St James, so a little suffering doesn't hurt (just kidding); and besides, I don't see any other way to get to Amboise.
The route ends beautifully in the narrow streets leading down to the Loire.

Walk taken in winter. It is not difficult. The section along the Amasse valley is truly charming. However, the return via the GR3 on the plateau and along the industrial estate is somewhat lacking in interest. But you are rewarded by the descent to the Loire east of the château, which is very picturesque. And then, when you arrive in Amboise, you can enjoy a meal or a drink in a beautiful setting.

We took the shortcut suggested by Michmill, which is really great and very easy to find. Thank you, Michmill.

A very interesting hike, done with a group of hikers. The description is very reliable and the route on the map is excellent. We did not make the return trip to Château Gaillard, as the section of the GR3 beyond point 14 was not maintained and the grass was knee-high. Rue du Vallum is poorly signposted on the return trip (sign not visible), just before Rue du Petit Bonheur.
Thank you for the safety instructions when crossing the D31.

I accompanied a friend who had downloaded the route.
I suggested some changes between points 2 and 6 for various reasons:
- to avoid tarmac
- to follow the Amasse even more closely
- to avoid going back and forth to Château Gaillard

To do this, we went to the car park near the castle (we crossed and followed the Amasse). At the end of this car park, a path leads to Clos Lucé. We then went to the entrance to Château Gaillard, crossed the Amasse again and went through a housing estate to reach Avenue Léonard de Vinci. At a roundabout, a recent path runs alongside the Amasse to point 6.
Further on, at point 12, we made a round trip to Saint-Règle.

A very pleasant and interesting hike due to the variety of the route, which takes you through the area around Amboise and into Amboise itself, offering some beautiful views.

I have chosen this route because I think it would be interesting to suggest it to my club. But it will probably be for next term. So I can't say any more about it.
Kind regards
