Dunes de Bon Abri

The 4 ha site of the Bon abri dunes, the only land area in the Baie de Saint-Brieuc Nature Reserve, is protected for its natural and environmental wealth.

Between sandy knolls and wet depressions, a veritable mosaic of natural environments is home to a highly diversified flora and fauna, including over 300 plant species, 150 species of fungi, around 600 species of invertebrates and 7 species of amphibians.
