Baie de la Fresnaye

Highlight • Beach

Located in the east of the Côtes d'Armor, on the Emerald Coast, the Bay of La Fresnaye is a foreshore of approximately 900 ha, favored for shellfish farming and in particular the cultivation of mussels and oysters. Its hydrographic perimeter is part of that of the SAGE Arguenon bay of Fresnaye, representing 20% of the surface of the latter. A flat and semi-enclosed bay, its relatively clear waters are a key factor facilitating the proliferation of green algae. Ulva type Ulva and other opportunistic algae such as Pylaiella littoralis are present and synonymous with the high trophic level of the bay.

Marais des Salines Wooden Bridge

Highlight • Bridge

The Marais Bridge is a reinforced concrete bridge built at the beginning of the 20th century for the Yffignac-Matignon railway line of the Petit Train des Côtes du Nord. It was designed by the architect Louis Harel de la Noë and is part of a series of works which have made it possible to develop tourism in the department. The bridge has been recently restored and hosts the greenway and the Euro Vélo 4.

The bridge offers a view of the Plurien lagoon, a marsh that lives to the rhythm of the tides and is home to lush vegetation. It is an ideal place for walking and observing nature. The GR®34 also passes over the bridge and leads to fine sandy beaches and pink sandstone cliffs.
