Car park at the foot of the mill, Rue de la Pâtissière in Saint-Herblain. There is a sign describing the walk in the car park.
(S/E) With your back to the sign, head right onto Rue de la Pâtissière (the mill will then be on your left). Continue until you find, on the left, a signpost marked ‘Route des Villages’. Take the small path indicated. After a steep descent, it turns right and runs alongside the Ruisseau du Drillet. Continue until you find a footbridge on your left.
(1) Cross it and turn immediately right to follow the shared section of the “Route des Villages – Route de La Chabossière”. Cross a very wet section via a boardwalk and continue until you reach a picnic area. Shortly after this, use the footbridge which will take you to the other side of the stream, onto an uphill path which you should take on the left. You will come to a house on your right. The path then turns left and becomes a tarmac road. A little further on, it turns into a path leading to Rue de la Porchellerie, near a sign for La Morlière.
(2) First turn left then right to take a path marked by a sign for La Bretinais. The path leads to a track that branches off to the left and winds around a few bends. Follow the sign for ‘La Coutelière’. After a short climb and a left-hand bend, pass the sign for La Coutelière. Another short climb with a house on the right, a slight bend to the left, and you’ll find a small path on your right which you take. The path climbs gently. You’ll see a beautiful white water tower on your left. At a fork, turn right. The path is then bordered on the left by a wire fence marking the boundary of an industrial estate. You arrive in the hamlet of Les Bouillons.
(3) Just after house No. 10 in Les Bouillons, take the small path on the right, signposted ‘Les Bouillons’ and ‘La Métairie’. At the end of the path, continue straight ahead along the track. At the end of Rue des Vieux Puits, level with the La Métairie sign, turn right onto a wide track. Carry on straight ahead until you see Rue de La Chasseloire on your left.
(4) Continue until you find Impasse de la Chasseloire on your left. It takes a first bend to the right.
(5) Turn right again at No. 8 (private property sign). The road turns into a short path leading onto Rue des Villages on the left. Continue along this path until you come to a
path marked ‘Route des Villages par le ruisseau de l’Orévière’.
(6) Follow this path until you reach a road. Take this road on your left until you spot, on your right, the start of a path alongside a stream (take care, as this start is not very visible). Follow this path, which leads to a fairly busy road. A sign on the left-hand side of the route reads ‘Circuit des Villages par le ruisseau de l’Orévière’. To cross the road, head left to the pedestrian crossing. Cross there, then veer slightly right to find the continuation of the path, which heads off to the left. Follow this small path straight ahead until you reach a fork with a signpost.
(7) Turn left onto the footbridge to follow the route towards the village of Basse Orévière or La Gâtine. This narrow path, which winds up and down like a rollercoaster, leads to a hamlet which you cross straight through. A steep descent brings you back onto a narrow path. Follow it until you reach the main road. Turn right without crossing to the other side, then, after a few metres, turn right again onto Rue de la Morlière.
(8) All you need to do now is follow the signs for ‘Moulin de la Pâtissière’. Take the path on the right just before a sign with raised stripes. The path turns into a track that will lead you straight to the Moulin de la Pâtissière (S/E).
