The Bay of Morlaix is classified as a Natura 2000 site in 3 protected areas, the bay and its islets, the Douron valley and the Monts d'Arrée, for their wealth of remarkable species such as the otter, the Petit-rhinolophe (bat) and the Atlantic salmon, and for their preserved natural environments such as the moors and peat bogs of the Monts d'Arrée, the seabed with its eelgrass beds, veritable underwater prairies, and the kelp forests.
This corner of Brittany is a preserved playground, little modified by man and offering runners a variety of routes. Cliffs, undergrowth in the valleys, ridges with the sharp schist summits of the Armorican massif, not forgetting the unusual circuit of the alleys of Morlaix where your steps will follow paths steeped in history.
