Merrien, an unspoilt peninsula
To the east of Brigneau, via the Sentier du littoral, the ria de Merrien can be explored in its natural setting. This exceptional protected site is an ideal place for a wide range of walks and is a real treat for hikers, as well as orienteering enthusiasts, thanks to the discovery trails in the Bois de Plaçamen (available from the Tourist Office).
For the best view of the ria, head towards the ocean on the right bank, where you'll also find the old customs house, known as "Maison Houard". It overlooks the sea and gave the customs officers a 180° view of the coastline. It's quite something, isn't it?
From the left bank to the right bank, take a walk in the heart of nature, in a preserved area that lives according to the tides. The Conservatoire du Littoral made it its first management site in Brittany in the 1970s, demonstrating its ecological and environmental importance.
