Parking Rue des Papeteries on the right-hand side of the Saint-Martin church, built in 1736 by architect J.P. Galezot, with its Comtois imperial dome covered with glazed tiles. On the church square, you can see an ancient calvary.
(S/E) Walk up Rue des Papeteries, passing the war memorial, then under the railway bridge. You will see yellow and blue markers that will guide you along the route. You will reach Rue de la Mairie. This building was originally a wash house.
(1) Turn right onto Grande Rue, passing in front of the town hall. 50 metres before a new railway bridge, turn left onto Impasse de Chantermerle, following the signs for Circuit des Belvédères, Rochers du Château Loriot. The climb to Rochers du Château Loriot is extremely steep.
(2) The tarmac lane quickly gives way to a stony path that leaves the village, winding its way through a pasture. Behind you, there are beautiful views of the church and the old paper mills silhouetted against Mont de la Côte au Bœuf and, in front, Montagne de Notre-Dame d'Aigremont, where you can see the chapel and Mont de Souvance.
(3) You enter the woods and begin to walk along the cliffs, always with caution. The staff map quickly indicates the Grotte de sous Roche. I think it is poorly located and seems to me to be much higher up. Follow the markings that appear from time to time, avoiding any paths that might lead to the cliff. At a clearing marked by a small sign saying "Attention Falaise" (Beware of Cliff), you will find an unsecured viewpoint that you should approach with great caution, overlooking the Grotte de sous Roche, which opens up on the side of the cliff. Do not try to enter it, as this is impossible. However, you can admire its large entrance porch and the view of Mont de Souvance and the meandering Doubs river. Continue climbing this path, which sometimes runs alongside the cliff, with exposed rocks that could cause you to trip: tread carefully and watch your step. You will also discover an unsecured viewpoint (caution) over the Val de Roulans.
(4) You will arrive at a crossroads, marked by signs, where you will head towards Laissey and Rochers du Château Loriot, continuing along the cliffs. Shortly afterwards, another sign invites you to descend to the right towards the viewpoint. The Belvédère des Rochers du Château Loriot overlooks the Doubs valley from a height of 491 m. In the distance, you can see the village of Laissey, which is your next destination.
(5) Turn back to rejoin the trail, which you take on the right, following the markings. Be careful! At one point, the trail leaves the ridge line, which is blocked by a yellow and blue cross, and descends slightly to the left. The open undergrowth makes for pleasant walking. You will come to a crossroads in the shape of an X. Climb to the right, still following the markings. 50 metres further on, you will pass a path on your left that descends the hillside. You will soon arrive at a crossroads marked by a sign, where you will head towards Aigremont. You will follow a Way of the Cross on your right, which will undoubtedly be your route, as this part of the trail, from Deluz to the Croix de Souvance, is quite a climb!
(6) You will soon arrive at the Chapel of Aigremont with beautiful views to the north over the Val de Roulans and to the south over the Jura mountains. After your visit, head back down towards the crossroads
(7) This time, turn left and follow the yellow-blue markings, avoiding the cross-country paths marked with a cross.
(8) You will come to another fork marked by signs. Take the left path towards Croix de Souvance. Make one last effort to tackle this unsecured path with caution and enjoy the magnificent panorama from this unique viewpoint at 460 metres above sea level, overlooking the Jura mountains, the Val de Roulans and the Doubs valley towards Baume-les-Dames.
(9) Turn back again to the sign and take the path on the left, which joins a wider path that you also take on the left. As you pass, admire the trees, which are probably centuries old, highlighted by the airy undergrowth.
(10) You will exit the forest and find a stone path that runs along the left side of the railway line and will take you to Laissey via Rue du Maroc, then Impasse Malle Planches, still guided by the markers. Opposite the station, go down the stairs and pass under the tracks via the underpass. At the roundabout on the right, take the time to discover the friendly soldier on the war memorial. Cross and go down (leaving the signposts) the path indicated by the sign for Chapelle - Deluz. 150 m after the chapel, turn left, joining the cycle route and the river banks.
(11) Shortly after the cemetery, leave the cycle path and take the D266 road, which you will follow carefully on the left-hand side, ideally walking on the grass on the other side of the safety barriers. You will pass under the Roches du Château Loriot.
(12) At the entrance to the village, turn left onto the small street that runs alongside the canal. Take a look at the Cul de Four (17th-century bread oven). You will pass the paper mill and its housing estates.
(13) Cross the bridge and continue along the canal on the gravel educational trail. You will reach the D226 at the exit of Deluz, which you will follow back towards the village on the right. On the way back, you will also discover an old millstone and a calvary. You will return to Rue de l'Église and the car park (S/E), but before that, walk about thirty metres into the Due du Breuil to visit the wash house and drinking trough dating from 1835.
The route includes cliff paths and unsecured viewpoints. The rocky path runs along the cliff and borders the precipice on small passages, and not all of the viewpoints are secure. You must therefore walk carefully and cautiously, as the rock outcrops could cause you to trip. Good footwear is essential and the use of walking sticks is recommended. This hike is not suitable for children.
