Description of the walk

The hike starts from the biscuit factory car park on Route des Traouïero.

(S/E) Follow Route des Traouïero until you reach the woods on the left.

(1) At the sign indicating the route, take the path on the left and descend to the small pond.

(2) At the pond, turn right and follow the yellow markings.

(3) Veer slightly to the right to stay as close as possible to the Grand Traouïero stream, which you will follow for a few kilometres until you reach the granite pillars lining the path.

(4) Here, take the small grassy path on the left which climbs up to the road at a place called Kerrougant.

(5) Turn left to continue along this road.

(6) Ignore the access road to Kergomar on the right and continue straight ahead. Pass the various turnings on either side and you will reach a sign on the left-hand side of the road indicating the Traouïero valley.

(7) Turn left to go down the path. At the first fork, turn right and follow the yellow "dragon" markings.

(3) Return to the starting point and retrace your steps to get back to the car park (S/E).

A pleasant walk in beautiful sunshine. I didn't find the route difficult to follow at all and the explanations were sufficient.

Very pleasant to sweep because it's surrounded by nature, trees, greenery and tranquillity
The only downside is that part of the route is on the road

I completely agree, but it can be fixed!
Perhaps some of the markings disappeared in the storm in November 2023, as there are lots of large fallen trees.
That would be good because this route is easy and very interesting, with a great atmosphere. It would be nice not to have to extend it with young children.

Very poorly marked route with numerous unmarked junctions. Potential for numerous route errors. Route marking needs to be reviewed!!!!!

A very pleasant hike in the Traouïeros valley, surrounded by unique, lush green scenery. The terrain is pleasant as it is very well maintained, with a special atmosphere and a reasonable amount of elevation gain.
On the downside, however, there is a serious lack of signposting, even just coloured markings to help you find your way at the numerous intersections. This happened to us, even with a high-performance hiking app.
But a very special moment.

For hiking, follow the easy Dragon Route. A pleasant hike in a shaded area.

Error in step 4. Do not immediately take the climb on the left after the pillars.
According to the map, you should continue on the right.
The pillars are located between Le Calvaire and Balaneyer.
The path indicated after the pillars goes up to Kergomar, not to a place called Kerrougant.

Indeed, the recommended parking spot is private. So I parked a little further away, a third of the way to point 1.
This meant a rather uninteresting drive along the roadside to point 1.
After that, the route itself was a lovely walk. The gigantic boulders are particularly impressive. The route is a little rough, but it was easy to find your way around.
And again, there was a 1.6 km stretch to cover along a road between points 5 and 7. This was also uninteresting.
It's a shame, but I suggest that future hikers on this route return by the same route (5>4>3>21...).
In mid-October, there are very few cars on these roads, but during the summer holidays, the traffic must be much heavier.

Hike started at point 1...The route is not particularly interesting, and the return journey by road is tedious in parts.

The biscuit factory car park is private, so park at point 1. There are many options for heading up the valley. If you return via the Kergomar road, climb up to Roch Lédan, a path through the gorse before car park 7, with panoramic views of the entire region.

A pleasant walk.
It's true that parking at point 1 rather than at the biscuit factory allows you to avoid the road section, which adds nothing to the walk.
We rejoined the trail at point 6 to avoid continuing along the road.

A very beautiful, relaxing and refreshing hike that takes place mainly in the undergrowth. The forest has a somewhat magical feel to it, and you almost expect to encounter trolls and other legendary creatures.
We decided not to continue along Rue de Pleumeur: when we reached the village of Kergomar, we turned left to rejoin the forest path, even if it meant retracing our steps.
We also decided not to park in the shop car park, as the distance to the entrance to the woods (point 1) was of no interest, and we set off directly from point 1.
