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.

View of Saint-Michel Chapel

Highlight • Viewpoint

The view of the Chapelle Saint-Michel from Erquy is striking: the small stone chapel sits on its own little island, just off the coast. Built in the 19th century, the chapel stands guard amidst the wild beauty of Brittany.

A few steps that take us to a beach far from everything. Small beach just magnificent. Great view. We feel alone in the world if we go there at the start of the day

It's a great place to admire the beach at the bottom of the cove and well worth taking a break from your run.
