Plage Saint-Guirec, Beach with pink granite rocks in Ploumanac'h, France

Plage Saint-Guirec is a beach on the northern Breton coast at Ploumanac'h, in the Côtes-d'Armor department. Its shoreline is broken by pink granite boulders that form small coves and shelter the sand from the swell. The rocks belong to the same granite mass that runs along this stretch of coast.

The site connects to a medieval sanctuary established when a Welsh monk arrived at this coastal location. This religious presence shaped the area's identity for centuries.

The beach takes its name from Saint Guirec, a Welsh monk said to have landed here in the 6th century; the oratory of Saint-Guirec stands on a rock just offshore at low tide. A small stone statue of the saint once stood on the beach, and local women are said to have stuck pins in its nose to find a husband.

The beach offers showers, toilets, and accessible pathways for all visitors. During warmer months, supervised areas for children are available and the rocks provide natural shelter from wind.

At low tide the beach becomes a natural pool system where starfish, crabs, and small fish collect in the rocky depressions. These temporary pools reveal marine life that is normally hidden beneath the waves.
