Park in the car park in the hamlet of Les Cordiers in the commune of Arc-sous-Cicon, rue de la Citadelle, near the old fountain.
Yellow and blue markings.
(S/E) Go up the street that passes in front of the water tower. Two hundred metres after the last house in the village, leave the tarmac road and continue straight on along a stony path. There are few markings other than those for the mountain bike trail, which follows the same route.
(1) This path leads to a clearing, then to a crossroads joining a tarmac road, which you take on the left. Continue along this road through a beautiful forest to the hamlet of Montigny.
(2) Pass in front of the Auberge du Crêt Monniot, covered with wooden shingles (wooden tiles, the traditional thermal insulation of our regions) and climb to the right to the ridge. Take the time to say hello to our charming Montbéliard cows, which have kept their horns.
(3) At the summit, the highest point in the canton of Montbenoît (1,141 metres), you will have a 180° view of the Jura mountains and, further afield, the Alps, with an exceptional view of Mont Blanc and the Eiger, the Finsterarrhorn (4,274m), the Jungfrau (4,158m), the Aletschhorn (4,182 m), the Weishorn (4,505 m), Monte Rosa - on the border with Italy - (4,634 m) and the Matterhorn (4,478 m). Unfortunately, in summer the view is obscured. There is a bench where you can take a short break or have a picnic.
Follow the yellow-blue marked trail that passes in front of the transformer. After a wooden chicane, look for the first sign posted at the corner of a barbed wire fence, then the second one below at a 45° angle in the middle of the pasture. The next signs, which are easy to spot, will guide you along the Sentier du Crêt Monniot trail into the woods, offering you a karst landscape with numerous sinkholes.
(4) This trail will lead you to a gravel road, which you will follow to the left. It quickly forks, but you will continue straight ahead to reach the Grange Nicod and then the Auberge again. You then have two options: walk back past the inn and down to Les Cordiers (the loop will be 10 km), or continue straight on towards Grange Brasier, leaving the marked path to enjoy the view of the mountains on both sides a little longer. The walk will be extended by five kilometres.
(5) After Grange Brasier, continue straight on towards Gilley until you reach the large farmhouse of Grange Brûlée. Walk 150 metres past it and turn left onto a stony path which, 500 metres further on, splits.
(6) Turn left again to climb to the top of Petit Mont (1,097 metres), which offers panoramic views of the surrounding area. Turn back to return to the Crêt Monniot inn and return to Les Cordiers, passing through the hamlet of Montigny again.
(7) 1 kilometre further on, after the transformer (be careful, there is also a poorly maintained path before the transformer that will lead you astray in the valley), turn right onto a stony path leading down to the Citadelle. At the tarmac road, turn left and return to Les Cordiers (S/E).
