To get to Le Perthus, take the D900. From Avenue de France, turn right at the gendarmerie brigade to go up towards car park no. 2, which is a pay-and-display car park. You can also continue along Rue du Fort (towards Fort de Bellegarde) to park outside the town, on the left-hand side of the road where there is a sufficiently spacious esplanade (parking for 4 to 5 vehicles). You can start from above car park no. 2.
(S/E) From the upper part of the car park, look for a building and enter the cork oak undergrowth to climb south-east to join theGR® 10trail and Rue du Fort well after leaving the town. Cross this road carefully, as there is a car park on the other side.
(1) You can start from this car park. Walk up the road towards the fort for a few metres before turning left to follow a yellow-marked path that winds through the vegetation, overlooking the road on your right until you reach a large grassy platform next to the road. Cross this road carefully to climb a fairly steep grassy path opposite (pylon with electricity meter). You will arrive at a gate in the fort near an old drawbridge.
(2) Enter the fort enclosure to observe the horizon to the north and east from the first line of fortifications. Depending on the season, it may be possible to visit the fort. Retrace your steps to return to the first gate, then continue straight ahead to a line of defences. At the end, leave the fort grounds to observe the south-western horizon again. Walk back down along the road and, further on, turn left towards the Panissars site and the 17th-century military cemetery. Beautiful view of the Spanish border. Arrive below at the old cemetery, also known as Col de Panissars.
(3) Climb the path towards the redoubt, clearly visible, via theGR®10. There are beautiful views from the redoubt over the Fort de Bellegarde, located higher up, as well as over Spain. Walk around it before continuing along theGR® to the Roman site of Panissars, through the cork oak trees. You will arrive at the remains of the buildings. Turn right to find traces of the Roman road connecting France to Spain imprinted in the rock. Climb the border hill to look out over the ruins.
(4) Go behind the ruins to return to theGR®10. Turn right. The trail winds its way uphill, continuing along the border. Looking back, you will see partial views of the fort and Le Perthus. The trail eventually descends before arriving at Coll del Priorat, near a water cistern.
(5) From the stony track known as the military road, climb steadily opposite, still following theGR®10, until you reach a fork much further on, where the track splits in two. Leave the military road and turn right.
(6) Descend this track, which crosses the Còrrec del Prat dels Pomers at its first circular bend to the right. Follow it continuously downhill towards Cortal Mirapeix and then Riunoguers. Stroll through the few streets of this hamlet.
(7) Retrace your steps to return to the cement cycle path you arrived on, continuing along it and keeping to the left as you leave the village (Mas Llong communal path). Follow it all the way to Mas Las Carbonères.
(8) Turn left at the second crossroads, staying on the cycle path. Continue along it until you reach the next junction with a yellow sign indicating Les Cluses. Turn left in this direction.
(9) Continue straight ahead along this path until you reach a large crossroads marked by a hunting hut. Then turn right.
(10) Follow the stone path that winds its way down the mountain, crossing streams as it goes. Without ever leaving it, return to the outskirts of Le Perthus. You will arrive at a large car park on the left, reserved primarily for coaches.
(11) From the junction with Rue du Mas Rimbau, turn right towards the town centre. Follow this road on the right-hand pavement. After passing a shaded boules court, turn immediately right to reach car park no. 2 (first possible starting point).
(12) Cross this car park, heading towards the edge of the cork oak forest, and join the (S/E).
