From the Saint Blaise district, take the Route d'Uchaux, the D12. Park on the D12 after the left-hand bend and the Pénègue leisure centre, in the first car park on the right.
(S/E) Follow the path through the woods, parallel to the road, towards Uchaux. You will arrive at a second car park.
(1) At the "La Roquette 94 m" signpost (at the side of the road), turn right into the woods (yellowPR® markings). Pass a picnic area with wooden tables, ignoring the paths leading off to the left. The forest, overgrown with sarsaparilla, takes on the air of an enchanted forest. You will come to a crossroads.
(2) At the "Noyères Est 134 m" signpost, continue straight ahead on theGRP® du Massif d'Uchaux (yellow and red markings).
(3) At the crossroads just after, leave theGRP® and turn right onto the DFCI track. At the next crossroads, stay on the track, keeping to the right twice. At the T-junction, rejoin theGRP® and turn right. Continue to a fork in the road.
(4) Leave theGRP® and continue left on the track. The path heads west, north of the Colline de St-Ariès, and joins a junction.
(5) Leave the return path on your right and continue left. After a right-hand bend then a left-hand bend, you will reach a crossroads.
(6) Go up to the right on the Jonqueirolles track until you reach the start of a path that is partially blocked by boulders.
(7) Stay on this track to the left, which climbs more steeply, then descends and passes a slope.
(8) Behind this embankment, keep to the left to stay on the Jonqueirolles track, which then runs along the hillside where several gallery entrances are visible. Be careful: despite the traces of passages inside these old quarries, there is a risk of rockfalls. Go past a DFCI barrier and continue opposite towards the houses until you reach the start of a DFCI track on the right.
(9) Turn right onto the Prat track after the barrier. You will reach a crossroads in a wide left-hand bend.
(10) Negotiate the bend and follow the track northwards to the remains of an old refractory products factory.
(11) Several buildings are visible, as well as a bridge with several arches. This rail bridge was used to transport wagons carrying clay. Please be careful and do not venture into the ruined buildings.
Back on the Prat trail, return to the bend.
(10) Turn left onto a path that runs along the hillside, which is also riddled with tunnels. Then keep left to climb the embankment and return to a fork you passed on the way to the Jonqueirolles trail.
(8) Continue straight ahead. This track climbs up to overlook a first lake on the left, which fills an old clay quarry. When the track descends, you will find the start of the path you took on the way up.
(7) Turn onto the path on the left that descends into the undergrowth. A little further along the main trail, a path on the right leads to the edge of a second lake, which you can walk around and back. Continue along the trail until you reach a mound of earth on the left. Climb this mound for a beautiful view of the first lake with its colourful edges. Return to the trail and turn left for a few dozen metres.
(12) Turn right at a right angle. Note the presence of rails, used by the wagons transporting clay during the quarry's period of operation.
Stay on this main track and turn right in front of a yellow sand embankment. Continue along the track, which leads to an open esplanade on the edge of the second lake, going around it on the left. Then climb up the wide path opposite, with your back to the lake. Shortly afterwards, you will come to the junction you passed on the way there.
(5) Go up the track on the left, in the opposite direction to the outward journey, to rejoin theGRP® at a fork, which you also passed on the outward journey.
(4) Turn left onto theGRP®, then cut right onto a path that passes behind the Bollène Communal Forest sign. At the T-junction, continue to the right. At the fork, take the left path to the "Noyères Est 124 m" sign you passed on the way out.
(2) Leave theGRP® and keep left, in the opposite direction to the outward journey, to find the yellowPR® markings and reach the road to Uchaux.
(1) Turn left onto the path that runs alongside it and return to the car park where you started (S/E).
