The start is a little further than Buvilly, on the Chamole road, at the junction with theGR® Yenne Besancon, at an altitude of 447 metres.
(S/E) Turn right, heading downhill, and veer slightly left at the first crossroads. Continue along this beautiful path until you reach a junction with a path on the left.
(1) Take this path uphill, turning sharply left, still markedPR®. Continue along this track, which offers numerous views of the valley and the outskirts of the village of Poligny.
Further on, you will reach a crossroads with a track on your left.
(2) (Here, you can shorten your walk by turning left and joining the crossroads a little further up, then continuing to the left).
Otherwise, continue straight ahead on the Grande Corniche path. After more views and a much more rocky area, the path turns left and joins a crossroads.
(3) At this crossroads, turn left, then 10 metres further on, turn left again and continue for 100 metres.
(4) On the path, look for a large stone marker. Turn left and head downhill. Continue straight ahead until you reach a crossroads.
(5) Turn right. Continue along this path, walk alongside pastures and, further on, you will reach a tarmac road.
(6) Turn right onto this road, then left at the first crossroads and shortly afterwards you will reach a large triangular crossroads with magnificent trees, tables and information panels.
This is the start of the wind farm trail.
Head left towards the houses and continue towards a farm. Walk alongside it and turn right, staying on the main road.
Cross the plain, pass a wayside cross and you will reach a junction just after the power line (elevation 585).
(7) Turn right towards the wind turbines. Further on, after a right-hand bend, you will come to a large three-way junction with three tracks.
(8) Turn left, then immediately right onto the dirt track, leaving thePR®. Continue until you reach a white path (elevation 585).
(9) Turn left and rejoin the marked trail. Continue until you reach a forest road. Cross it and continue straight ahead, leaving thePR® trail again.
Continue along this straight line and you will come across another marked trail.
Turn right and look to your left to find a line marked "Arbois 48".
(10) Turn left and continue. Ignore the first two paths you come to, then you will reach a beautiful path crossing your trail (visible on the IGN map when you zoom in).
(11) Take this beautiful, fairly wide path on your left. Continue straight ahead until you reach a large white path.
(12) Turn left and head towards the arboretum and hunting lodge.
Continue straight ahead, taking a path lined with signs bearing children's names.
Continue along a pasture. Reach the end of the pasture and the directional signs.
(13) Turn left towards the Gallo-Roman fanum. You are now back on theGR® Yenne Besançon, also known as the Échappée Jurassienne in this area.
Continue along this track for a while until you reach a crossroads.
(14) Ignore the path on the left, continue straight ahead and start descending until you see the tarmac road.
(15) Without turning onto it, turn left onto theGR® trail, continue to the tarmac road and you will find your car park (S/E).
