Côte de Granit Rose

The coast stretches thirty kilometers from Plestin-les-Grèves to Louannec with formations of pink granite along turquoise waters. Massive rounded rocks rise from sand and seawater, creating coves, caves, and natural arches. Tidal pools form between boulders at low tide, sheltering marine life. Vegetation grows on cliffs above the tide line.

Geologists date the granite formation to approximately three hundred million years ago. Quarries near La Clarté supplied building materials for churches, lighthouses, and residences starting in the sixteenth century. Tourism developed during the late nineteenth century with construction of hotels and villas. Today environmental regulations protect the natural features from excessive development.

The region has inspired artists, writers, and architects since the late nineteenth century. Hotels and villas along the coast feature granite from local quarries. Several municipalities organize festivals and cultural events that combine maritime traditions with modern tourism. The coastal landscape remains a popular subject for painters and photographers.

The GR 34 hiking trail connects multiple beaches and provides access to the coastal formations. Visitors should consult tide tables to explore tidal pools during low water. Parking areas are available at Ploumanac'h, Trégastel, and Perros-Guirec. Local tourism offices provide maps and boat excursions to the Sept-Îles archipelago. Sturdy footwear is recommended for rocky terrain.

Similar geological formations exist only in Corsica and China worldwide. The stones show color variations from pink to grey, with intense rose hues visible during direct sunlight. Erosion patterns have shaped some rocks into recognizable forms that carry local names like Le Chapeau de Napoléon and Le Dé.
