Away from the seafront, the Coteaux d'Ermur circuit reveals a more confidential side of Pornichet. This 7.8-kilometer loop invites walkers to explore a rich natural environment, shaped by water, vegetation and the gentle relief characteristic of the Ermur area.

Along the way, the landscape alternates between hedged farmland paths, wetlands and natural environments ideal for observing the local flora and fauna. This hike allows you to discover an often little-known natural heritage, where the presence of water contributes to the area's ecological diversity.

Marked out as a Promenade et Randonnée (PR®) itinerary, the trail offers an accessible outing for walkers wishing to enjoy a peaceful setting, far from the hustle and bustle of the coastline. It starts from the Chemin de Baudry. As it crosses wetlands, some sections may be more or less passable, depending on weather conditions and water levels.
