Between Tregastel and Perros-Guirec, the Trauero Valley and its chaos of pink granite. [en images] – Walks in Tregor



The valley of Trauero, located right between the communes of Tregastel and Perros-Guirec, whose Kerugant marks the border, owes its name to the cartographers of Louis XIV, who thought that Trauiero was the name of the place, whereas in Breton it means valleys. Indeed, Trauiero consists of two deep valleys through which Kerugant meanders. The stream splits before flowing into the sea: the small Trauiero arrives at the Ploumanac ice mill (Milin Roux), the large Trauiero arrives at the Tregastel wheat mill (Milin Glaz).

To reach this natural place, reminiscent of the chaos of Huelgoat, in Finistère, seven entrances are possible, but the most interesting and easiest section is from the Kergomar road. Then all you have to do is follow the directions on the beautiful terminals scattered around each entrance.

Plant and mineral in perfect osmosis

And forward for unusual discoveries! Having descended to the bottom of the valley along a beautiful path, just follow the Kerougant stream towards the sea: there are waterfalls, here huge blocks of granite playing tightrope walkers, ingenious paths, amazing trees, like this chestnut oak, whose peculiarity is that the trunk is very low branches, huge ferns (including the royal osmunda, a fern that has been around for 300 million years!). Not to mention the reservoir of the old mill, Lost logoden (mouse tail) pond, so named because of its shape and perfect for a snack…

Three caves, three stories

And that is not all! How not to stop at the aptly named smugglers’ cave, which during the war served as both a refuge and a stable where the horses coveted by the Germans were hidden. We stand without problems.

And to that leper, where, they say, a certain Jan ar Pronz lived in the 19th century, a hermit whom the locals came to feed, putting food in a trough dug out of granite at the entrance of the cave.

Finally, a long stop to admire Corrigan’s Cave: there, under a large rock, a strange village nestled. Feel free to leave a note in the specially designated “boest-lizheroù korriganed” mailbox!

Mobile crane, separate place

It is the only place in the Trauero Valley with the Lost logoden reservoir, a reminder of the sector’s industrial past. Eight tall pillars of pink granite rise out of the vegetation. They testify to the extraction of granite in the quarry of David. These pillars are the remains of an ingenious rolling bridge that was traversed by carts carrying granite blocks over raised rails in the early 20th century. A real technical feat!

The excavation part of the quarry to the right of the overhead crane is partially flooded today. In the rise to the left, a small building in ruins is buried in ivy. It was probably a quarry forge, an important element in the cutting of granite. (Telegram/Francoise Tavernier)

* Pink granite, known as Clarte granite, is largely due to the presence of iron oxide in the rock. This particular color of granite, which made Perros-Guirec famous, is found only in three places on Earth: on the Rose Coast of Granite, in the gorges of Piana, in Corsica and in China.

During the summer, the Tourist Office of the Côte de Granit Rose organizes night tours of the Trauero Valley with a guide and storyteller.
