How did the Pink Granite Coast form?

The Pink Granite Coast – Côte de Granite Rose stretches over 20 km from Trebeurden to Perros-Guirec in the department of Côtes d’Armor.

The eccentric pink granite formations and pink sand beaches are the key tourist attraction of this littoral.

Granite is a coarse-grained and impermeable crystalline rock mainly composed of quartz and feldspar with flecks of mica.

The colour of the granite depends on the amount of feldspar it contains.

It can vary from pink to lavender with flecks of gold and white and sometimes dark gray and black.

However, Pink Granite is the rarest form of granite available.

It is mined only in Brazil, China, Corsica and Brittany!

Millennia of wind, sea salt, ice and rain erosion created the jagged littoral, shaped the boulders and turned the small rocks into fine pink sand.


Perros-Guirec – Perroz-Gireg in Breton – is the most popular seaside resort of the Pink Granite Coast.

It is indeed renown for its two beaches of fine pink sand.

The Plage Trestraou is sheltered from the sea breeze.

It is therefore an ideal spot for a lazy day of swimming or sunbathing.

The Plage Trestrignel, on the other hand, is for those in search of authenticity.

Its jagged coastline is indeed more exposed to the winds and therefore less busy.

Both are superb, it’s just a question of taste!


If you enjoy hiking and want to make the best of the stunning Pink Granite Coast, you might want to follow the coastal path.

Le Chemin des Douaniers leads to Ploumanac’h at the mouth of the Traouiero Valley, a former smugglers haunt.

The picturesque fishing village depends from the commune of Perros-Guirec.

Not only it is a popular seaside resort, but it also the section of the Pink Granite Coast with the highest concentration of rocks!

Most are in the Parc Municipal that stretches from Pors-Kamor to Pors-Rolland.

This section of the coastline has some of the most suggestive rock formations.

You’ll therefore find Napoleon’s Hat but also a rabbit and a witch, to name a few.
