The Prat and Livet paths in La Vicomté-sur-Rance

Throughout this route, there are no fewer than five viewpoints from which you can admire this small coastal river, famous for its mouth between Saint-Malo and Dinard thanks to the tidal power plant dam. After following it first through fresh water and then salt water, you will end your route by taking sunken paths that will lead you to a monument dating back five thousand years.

Description of the walk

Car park at La Vicomté-sur-Rance Town Hall.
The entire route is marked in yellow.

(S/E) Leave the car park and take Rue de la Mairie on the left. At the roundabout, take the path lined with pruned oak trees opposite. Join a small road and continue on the right. At the crossroads near a farm, keep right on the road and enter Le Châtelier via Rue des Fresches.

(1) Turn left onto Rue de l'Éperon Barré. Continue straight ahead on the gravel path. Turn right (see note below) onto the first path and descend towards the banks of the Rance.
Go around Éperon Barré. At the slipway, enjoy the view of the Rance and after 50 metres, follow the street to the left to return to the crossroads you passed on the way there.

(1) Turn left onto Rue du Mont Joly, then left again onto Impasse du Val. After 20 m, take a small path that descends to the right. After crossing a stream, climb back up to the road. Turn left.

(2) At the highest point of the road, at a place called Foumoy (altitude 51 m), in the slight right-hand bend, enjoy the view with Dinan and Taden on the left bank on the horizon.

(3) Before the first house in La Ville ès Pois, take the sunken lane on the left. At the calvary, continue straight on along Rue des Vignes and, when you reach the banks of the Rance, turn right onto Rue du Port.

(4) Go under the bridge, cross the barrier and continue along the path. Cross the stream on the left via a ford and continue to the left to overlook the banks of the Rance. Go under the Pont de Lessard (railway bridge). Continue along the river.

(5) The path becomes a road as it veers to the right. Go around the Morgrève mudflat by turning left to cross the waterway and then turn left again to rejoin the banks of the Rance. Continue to the mill.

(6) At Moulin du Prat, admire the view of the Rance one last time and continue along the path. It doesn't matter whether you turn right or left, as both directions meet up a few hundred metres further on. You will reach Ville Hervy. Turn right and follow the road south, then south-west.
As you approach the houses of La Vieille Vicomté, turn left. At the bend, continue straight ahead on Chemin des Ruettes. At the end of the road, turn right and cross the railway line.

(7) Turn left and follow the path that runs alongside the railway line. After a section through the woods, turn right at the edge of the woods. Continue along this path, which ends at Route de la Source. Follow it to the left for 200 m.

(8) Turn right towards La Ville Bennefray. Take the first road on the left. At the end of the road, continue straight ahead along the sunken lane. When you reach another lane, turn right, then right again, and you will reach the lane covered by a gap on the left, thirty metres before the road. Join the D795.

(9) Follow the road to the right for about 100 metres and turn right towards La Basse Lande. At the crossroads, continue straight ahead. Ignore a street on the left and take the next one on the right. Cross the hamlet of Launay-Jannais. After the sports field, turn left and head for the Town Hall car park (S/E).

Notes

After (1), do not miss the hairpin bend to the right, as the path continues on another route towards Dinan, also marked in yellow.

Please note that the path sometimes runs along the edge of the cliff overlooking the river. It is wide and clear enough not to pose any difficulty, but we do not recommend it for young children.

Worth a visit

Châtelier Lock: This lock marks the boundary of the Rance estuary. Once you have passed through it, you enter the river domain via the Ille and Rance canal, part of the "Manche-Océan" navigable link.
This 221 km link between the Châtelier lock in the north and the mouth of the Vilaine in the south includes 24 navigation dams, 61 locks, 5 feeding ponds and 237 km of towpaths and service roads. It is operated and maintained by the Brittany Region.

The small fishermen's huts on stilts that you can see along the Rance are called "carrelets", named after the huge square net used for fishing. A flatfish also bears this name.

The souille de Morgrève: a souille is a small, steep-sided valley (similar to an abers) filled with silt and carved out by a stream that flows into the Rance. Until the19th century, souilles were used as landing stages for loading and unloading wood, maerl and seaweed, as well as all kinds of agricultural and livestock products.

The Bois du Rocher covered passage: it stretches 11.50 m in length along a roughly east-west axis. It is approximately 1.20 m wide. It has retained two capstones, one of which is still in place (length 2.65 m, width 1.40 m and thickness 0.55 m). This megalithic monument dates back more than 5,000 years.

An afternoon stroll in the sunshine! No problems on the route except for two trees blocking the path. The trail is easily passable, even along the Rance. There is a bit of road, but it's still acceptable. I preferred to go over the hills rather than along the edge of the Rance. The trail overlooking the village of Le Chatelier is pleasant with its paved section. A beautiful walk, charming even in December. Many paths cross along the Rance, the important thing is to go in the right direction.

Hello, This hike is definitely worth doing. Most of the route is through woodland and a large part runs alongside the River Rance. I would therefore recommend this route. Unfortunately, there are some negative points: the GPX track is inaccurate, which leads to errors in the route. It would be useful to redo it. At the end of the route (approximately 3 km from the end), after leaving the banks of the Rance, the path becomes impassable because it is not maintained and, in addition, the farmer who cultivates the neighbouring field has not hesitated to throw some bushes onto it. You then have to walk across his field. A little further on, part of the trail is very muddy, which leads me to believe that in case of rain it becomes impassable.

A slight disappointment for this walk. The entire section along the Rance river is attractive. However, visibility is obscured by vegetation for most of the route. A few beautiful viewpoints do make up for this, though, allowing us to appreciate this lovely region. Check the opening hours for visits to the Moulin du Prat mill.
Some sections on the eastern part of the route are no longer maintained. This is particularly true of the covered walkway at Bois du Rocher (at 9).
The textual description is generally insufficient. We recommend using GPS on the Visorando app. In this case, it is best to follow the trails on the IGN map.
A wonderful celebration at Lyvet on 14 July.

The first thing to say in order to avoid any controversy is: A superb outing, a very pleasant hike that I thoroughly enjoyed. The variety of landscapes, beautiful views, etc.
Even though we only met three people, it's clear that these trails are well-used, which is great because they're really worth it. It's very beautiful!
So I highly recommend it.
That being said, I am a local, and fortunately because:
- the route description is approximate, more or less accurate, but sketchy and incomplete.
- the yellow markings are old, faded if they ever existed, i.e. often difficult to see and even absent or hidden by vegetation. Many crossroads remain "hit or miss".
- The authenticity of the trails remains one of the strong points. However, it is important to note the complexity of certain passages.
- Overall, a great walk, but insufficiently and poorly marked.
A pity.

We took a wrong turn once near the Prat mill; please review the description of this location.
After visiting the mill, do not take the path leading to the mill and the car park. Go back up the steps and take the path on the left.
Otherwise, it's a very beautiful route that shows us the most beautiful places in the region, with the banks of the Rance overlooking magnificent, enchanting woods. Well done!

A hike where there are practically no markings, wooded trails, sections on the road, the path along the Rance is quite steep, beautiful views of the Rance and the fishermen's huts. Recommended for people who walk regularly. Luckily we had our mobile phone to guide us. A lot of work needs to be done on the markings, which is a shame.

Very beautiful hike, pleasant with superb views of the Rance, but a very big problem with the signposting. A significant lack of signposting, or even none at all, along the entire route, making it easy to get lost.
Some paths are poorly maintained and impassable (brambles), forcing you to detour through fields
which means you lose track of the route.

A beautiful and interesting hike. Take the time to visit the mill and listen to the story of its restoration.
As for the signposting, you do need to pay attention in a few places.

A very pleasant hike that I really enjoyed for its variety of landscapes, the rustic nature of the path and its very natural feel.
Despite it being a beautiful day in July, I didn't meet a single person!
So I highly recommend it.

A few points for improvement, however:
- The route description is accurate but brief. It should be sufficient, but you need to pay attention.
- The yellow markings are old, meaning they are often difficult to see or even missing.
- The GPS track (I hate it, but in some places...) is approximate on various sections. So don't follow it blindly, but use your common sense.
- The rustic nature of the path is a strong point, but it is sometimes so rustic that you have to go around fields of brambles.

I enjoyed this route, which I did at low tide; I will do it again at high tide or rising tide to appreciate the maritime part of the Rance in a different environment, particularly the Mongrève mudflats, the mill and the fishing huts.
Point 8: you have to look for the trace of the "sunken path" which disappears under the tall grass that invades the area at this time of late spring.

A beautiful walk in the usual glorious Breton weather, with sunburn guaranteed even though we are often in the shade of the woods, thankfully!
Lunch at the Moulin du Prat viewpoint, spectacular at high tide.
Thank you Visorando, as they say on Quotidien!

Beautiful views of the Rance.
A pleasant elevation change.
The section between the Vicomté dam and the Prat mill is really beautiful as it runs alongside the Rance.
Given the weather conditions in the preceding weeks and days, the ground was particularly muddy in places along the route.
Due to the 6 p.m. curfew, I was forced to bypass a section at the end of the route east of La Vicomté.
