Park in the Valmy Park car park (easily accessible from the RD 914 dual carriageway).
(S/E) Leaving the car park, walk along the castle wall beside the vineyards and descend into the woods to reach a track.
(1) From there, the route is marked in yellow all the way. Climb up to the left along this track until you reach a three-way junction.
(2) Take the path that climbs up to the left. The ascent is gradual and rejoins the track a little higher up, which you should follow for a few dozen metres.
(3) Turn right towards the Tour de la Massane. Follow this path which climbs and zigzags through the woods on steep, rocky terrain. Follow the markings carefully. After a steep section, you will arrive at a track.
(4) Cross the track and continue straight ahead along a path carved into the rock. After this steep section, the landscape opens up a little and descends slightly to a large intersection of two tracks at a cistern.
(5) Pass the intersection and climb to the right towards the Tour de la Massane. Cut across another track and rejoin it a little higher up at Coll del Camp d'en Selva.
(6) Continue left on the track for a few hundred metres, then climb up a path on the right in a fairly steep, open area. Then return to the forest and turn slightly right, following the marked path (which does not correspond to the one on the IGN map) to reach an intersection at an altitude of 662 m.
(7) Begin the final climb to the Tour de la Massane on the left. At the edge of the forest, the tower is located due south on a promontory. It is accessed by a few steps, which lead to a small orientation table.
(8) Begin the descent via the same route as the ascent until you reach the intersection at an altitude of 662 m.
(7) Turn left to descend to Parc de Valmy, making a circular route. After a nearly horizontal section, you will arrive at an intersection at Roc del Grill.
(9) Turn right and tackle a steeper part of the descent, particularly when it is exposed, following a power line. Shortly afterwards, you will reach an intersection at a track at Mas d'en Bardès.
(10) Turn right onto a path that climbs towards the Chapelle Saint-Laurent. After a few winding sections on a slope, you will arrive at this pretty little chapel. Turn right in front of it to reach a track.
(11) Follow this track, which descends to the left towards Parc de Valmy. Pass a first intersection at a cistern, keeping to the right, then a second one shortly afterwards, turning left. At the end of the track, continue along a small road that passes a few isolated houses and, just after a bridge, climb up to the right to return to the starting track.
(1) Climb up into the woods on the left to return to the car park (S/E).
