The starting point is the Châle car park, located in the heart of the village of Jeurre (at the junction of Montée de l’École and Rue Principale).
(S/E) Take Rue du Monument, passing below the church and the cemetery.
(1) Continue along the street to the right, passing the entrance to Jeurre Castle. A few metres further on, turn right onto a path leading down to the banks of the Bienne, then follow the river after passing under the bridge to the left. You will reach a bridge.
(2) Cross it, then at the fork, continue straight on towards Saint-Romain. Not far on, at another fork, turn right and head uphill. Look out for the start of a path on the right and take it (no sign visible): after a stretch of uphill and downhill, you’ll reach a stream; without crossing it, head left.
(3) Head towards a statue of the Virgin Mary visible straight ahead: the entrance to the cave, closed by a door, is just behind it (entry is prohibited).
Go back a short way and take the path on the left, heading downhill. After crossing a small stream, you’ll come to a fork; take the left-hand path towards the Vaux stadium along a wide track (marked with yellow and redGR® de Pays signs). Walk for about 900 m until you reach a fork where the right-hand path is off-limits (private property).
(4) Continue left, then left again uphill about 50 metres further on. You will then leave the yellow and red markings and follow the path for a short while alongside a stream (Leat de Creuse).
(5) At the boundary of a private property (sign indicating the presence of stallions), continue to the right towards Saint-Romain. The slope is a little steep at first, then becomes gentler. After a bend, turn right to join another path a little further up and continue to the right. Not far on, join another path and continue to the left, passing under some power lines. You’ll come out onto another path just before the hamlet of Petit Châtel.
(6) Continue to the right (yellow markings).
(7) After a bend, look out for the start of another path on the right and take it (unmarked section).
After a short climb, you’ll reach a fork; keep right.
(8) Take the path marked in yellow and red –GR® de Pays – on the right. A little further on (about 300 m), look out for and take a path on the left that climbs quite steeply for a short distance (a few blue markings visible): after reaching a small plateau in an open area, continue to the right (lovely views). A little further on, rejoin theGR® de Pays: continue left until the fork (Roche de Vaux) and follow the path to the right downhill (yellow and red markings). Further down, at the junction with the Chemin de la Chapelle, continue to the right (yellow markings) for about 200 m.
(9) Saint-Romain-de-Roche Chapel: Romanesque in style, it was probably built in the 13th century. From here, you can enjoy a lovely view over the Bienne valley. Return along the same path and continue straight on at the fork you passed earlier. Enter the hamlet of Saint-Romain-de-Roche.
(10) At a junction, take the road on the right, heading uphill towards Pratz. At the last houses, ignore the path on the right leading to Molinges and continue straight on until the fork (a place called Sous Chamu).
(11) Take the path on the right, which climbs slightly. Shortly afterwards, the path begins to descend: look out for the start of another path on the right.
(12) Take this path. About a hundred metres further on, turn right atthe first visible path (marked by a sign = Chemin de Philippe known as "Le Général"). Take care as the ground can be slippery in wet weather. Then head right at the fork (moderately visible) to reach a junction of paths.
(13) Continue along the path opposite (do not follow the yellow and red markings) and follow it for a short while; the route is relatively flat.
(14) At this point, the path runs along the foot of a cliff (Roche de Chiriat) where you can enjoy a lovely view of the valley. Ignore another path on the right (coming from Saint-Romain) and then another on the left: the route follows a recently created path (follow the pink markings). A little further on, you’ll come across a path leading to the Chapelle Saint-Romain de Roche; shortly after that, take a path on the left heading downhill.
(15) Near the Stade de Vaux, you’ll reach a wide path. Continue to the right and ignore the paths veering left at an open clearing. After a short while, you’ll reach the hamlet of Au Brotteau at the edge of a wooded area.
NB: I suggest a lovely alternative route along the banks of the River Bienne, which I highly recommend (about 1 km extra): click here to find out more.
(16) The path then winds its way through a series of short ascents and descents to reach a fork you passed on the way out.
(4) Continue straight ahead. At the access point leading to the Grotte de Nerbier, continue straight ahead again and cross the bridge.
(2) Continue straight on and follow the road past Jeurre Castle.
(1) Keep to the right to return to the starting point (S/E).
