The Lac de Haute-Mayenne and the Saint-Fraimbault-des-Prières dam

The Lac de Haute Mayenne, artificially created by the Saint-Fraimbault dam, will charm you with its rich and varied flora and fauna. But this route will also allow you to discover the confluence of two rivers that feed into the Mayenne: the Varenne and the Colmont.

Description of the walk

Coming from Mayenne, follow the D23 north towards Ambrières-les-Vallées. Before entering the town, at a place called Vaux, turn right towards the swimming pool, campsite and leisure park.

Parking: car park at the Vaux Leisure Park.

(S/E) Walk along the Varenne for about 100 metres to reach the footbridge over the river.
Turn right onto the footbridge, then right again to walk along the river. After a bend to the left, take the footbridge on the right that crosses the Mayenne.

(1) Continue to the right along the river. Continue on the path that veers slightly away from the river, leaving the houses of La Frételière on your right. Cross the road leading to these houses and turn south to reach the riverbank. Continue along this bank. Pass the Saint-Joseph Chapel on your left, then Château Malortie. Walk past the houses of the estate.

(2) Turn right onto the path, cross the Ruisseau de la Foucaudière and head south towards L'Auguisière. When you are 100 metres from the houses, turn left then right to reach a road. Follow this road, still heading south, to La Mortevrie.

(3) Leave the road by taking the path on the left, cross the Pigray stream and, after 100 metres, turn left towards Saint-Georges de l'Isle. At the calvary, turn right and pass the houses of Mézeray.

(4) Turn left to cross the Saint-Fraimbault-de-Prières dam. Take the road that curves sharply to the right and ends at the D151 departmental road at a place called La Blanchardière.

(5) Turn right and follow the departmental road to La Haie-Traversaine. Before the first houses, take a path on the right that leads to the Presbytery. Leave this house on your right and head to the left.

(6) Take Rue du Presbytère to the church, turn left into Rue de l'Église and then immediately right into Rue de Normandie. Take care. The road crosses the Colmont, the second tributary of the Mayenne, and continues for 200 metres.

(7) At Petit Pont, leave the main road and take a service road on the left that runs alongside the river. Continue along the path on the bank of the Colmont, then turn right to join the road leading to the dairy farm. Follow this road for a few metres on the right.

(8) Turn left onto the first path and head north along the road. Pass through the hamlets of La Guéhérière and La Tardinière. Follow Rue de la Croix de Beauvais to the D23 road.

(9) Cross the departmental road with great caution and continue opposite on the path that runs alongside the houses of Croix de Beauvais. Make a wide right turn, then turn left, leaving the footbridge at the start on your left, to return to the car park (S/E).

Notes

La Mayenne: this name refers, of course, to a department (53) located in the Pays de la Loire region between Sarthe (Le Mans) and Ille-et-Vilaine (Rennes). It is also a river, which gave its name to the department, and a town of 13,000 inhabitants, the sub-prefecture of the department.

The route includes too many roads, some of which are dangerous over long stretches, when there are better options in this beautiful setting.

Description needs improvement, a bit pompous, let's say "old-fashioned": no one hikes with compass directions ("head south" or "go north"...) or "keep it on your left" anymore.
The route offers beautiful views and is interesting from the start to point 4 (picnic area, information panels about the dam, photo exhibition, etc.) and consists of shaded paths along La Varenne and the reservoir.
For the rest:

from point 5 to the finish: uninteresting country roads (almost 100% tarmac),
dangerous section from point 5 to 7 along the D151,
from 7 to 8, you follow La Colmont but 10 metres behind the stone storage areas of the quarry...

Please note: public toilets opposite the church in La Haie-Traversaine (point 6).
So my advice: it's better to do a round trip starting at point 4 or see if there's a way to rejoin the greenway to the north to make a loop.

A long stretch of road from the dam to Ambrières. We set off from the hedge crossing so we wouldn't have to do the whole stretch of road at once. There are no signposts between the campsite and the dam. The Mayenne river serves as a landmark.

A very pretty route, but not one to attempt after six months of rain, as some sections become impassable, forcing you to climb the hillsides...

Beautiful route in the first half, much less interesting afterwards.
Poor signage, many missing signs and directions to private passages.

We had a lovely Sunday doing this hike, which is very pleasant along the river before the dam, where there are lots of fishermen, and then along all the tributaries of the Mayenne. In April, we were lucky enough to see the snowdrops in bloom, which was magnificent.
At the start and finish points, there are numerous tables available for picnics.

Picnic facilities available at points 4 and at the start/finish.
A small but welcome change to avoid walking on the road: at point 5, follow the yellow "Tour du lac" signs to return to L'Asnerie.
A very beautiful, varied walk with lots of views of the water.

A superb first half, but unfortunately, the second half is three-quarters asphalt, which is far too much for me.

Hello,
Hike started around 10:00. Arrived at point 4 around 12:30. A real treat (hence the duration...) due to wildlife (bird) watching.
Point 4: picnic table: Perfect!
Point 4 - Arrival in the afternoon: less interesting for me than the morning, which was just perfect! Lots of tarmac but hardly any traffic except on the D151, where you have to be careful...
Points of interest at the end of the route (points 4 to 9): View of the reservoir, mill, Mayenne countryside, some beautiful stones.
I confirm: there is a mistake at La Blanchardère; you have to go straight ahead and take the first road on the right to reach the D151. Follow the signs on site, which give the correct direction.

Conclusion:
To get the most out of the walk: a good pair of binoculars is essential and pay attention to every little movement: don't hesitate to look up... AND TAKE YOUR TIME!

Now it's your turn to enjoy...

Hike completed on foot in January 2021.
A very pleasant route under the winter sun. A few places to sit and eat here and there along the way. Very easy to follow (plenty of signposts).
