Park in the car park opposite the monastery (Chemin de l'Abbaye).
(S/E) Opposite the monastery, turn left and walk a few dozen metres. Take the small dirt track on the left, pass in front of a chapel ( if the weather is good, you will have a magnificent view of it), then continue to the antenna.
(1) Continue right on Chemin de Boeschepe. At the crossroads, turn right onto Chemin de l'Abbaye. Ignore a dead end on the left, then, about 50 metres further on, turn left to return to Chemin de Boeschepe. Turn right.
(2) Turn right onto Chemin de la Boulangerie, which is closed to all motor vehicles. Continue along a small street until you reach a fork (Route du Mont des Cats). Turn right, then, at the entrance to the bend, turn left onto Chemin du Moulin. At the four-way intersection, at the Auberge du Catsberg, continue straight ahead and, after a wide right circular, you will come out onto a road.
(3) Turn left and then right a hundred metres further on. At the end of the dirt track, turn left at the hairpin bend, follow the wooded area and rejoin the road. Continue right until you reach the bend.
(4) Turn right again and enter the Bois de la Source. At the crossroads, turn right and you will come out onto a road crossing the Col de Berthen (Chemin du Mont des Cats). Continue left until you reach the first crossroads.
(5) Turn right onto Chemin du Peenacker, towards Berthen. Continue to the right-angle bend and take the dirt track opposite to cross the woods and return to the antenna.
