Couronne du roi Gradlon

Couronne du roi Gradlon is a pink granite rock formation on the Brittany coast, with irregular shapes that create a crown-like outline. The stone displays the reddish tones typical of granite found in this coastal region.

The name refers to King Gradlon, a 4th century ruler of the ancient Cornouaille region in Brittany. This connection to royal history has given the location cultural significance.

The rock connects to Breton folklore through stories of King Gradlon and the sunken city of Ys, narratives that locals have shared across generations.

You can reach the formation from Grève Blanche beach via marked trails or through Rue du Panorama in Trégastel. The pathways are well marked, making it easy to approach the rocks from either direction depending on where you start.

From the top, visitors can spot the Tanguy and Rabbit islands and use the orientation table to identify coastal landmarks. This elevated view offers an unexpected perspective on the Atlantic islands nearby.
