Park in the car park of the Braine-l'Alleud municipal swimming pool, accessible by car via the Brussels Eastern Ring Road (R0), exit 24, and the Route de Piraumont.
(S/E) Head to the end of the car park and follow the sunken path that starts there. At the end of it, take the tarmac road to the right until you reach Route de Piraumont.
(1) Cross it and continue along the street opposite, Rue des Hayettes, until you reach a small chapel by the roadside on your left. It may be partly hidden by tall grass. Opposite, very old pollarded willows grow in the meadow.
(2) Walk back about ten metres and take the Timpe-et-Tard path leading down to the left between the meadow and a field. Be careful, as this path is tricky due to the tall grass and nettles, which may conceal ruts left by mountain bikes. Then join Rue Timpe-et-Tard. Walk up it and then cross Chaussée d’Ophain with care. Continue straight ahead and join the Chemin de la Justice, which you follow to Village No. 1.
(3) Turn right onto Chemin de la Justice, then immediately right onto a footpath which leads onto Avenue de la Ferme. Continue in the same direction, take the left-hand bend, then at the next junction, continue straight on along Chemin du Pré de la Perche.
(4) Turn right onto Rue des Arbalétriers to reach a crossroads.
(5) Turn right onto this path, then continue right onto Rue des Archers. Cross Chemin des Pères and continue straight ahead for about 50 metres. Turn right onto Rue Maurice Maeterlinck, then right again onto Rue Jules Bordet and join Route de Piraumont. Turn left, cross the roundabout and continue along the cycle path to the park entrance.
(6) Here you have two options:
- the shorter route: continue along Route de Piraumont to reach the swimming pool car park directly (S/E).
- the longer option, following the route: turn left and follow thefirst pond on the left. Then go round it until you reach a bridge on the left.
(7) Cross the bridge and continue, staying on the main path. You will reach the water catchment area, where a path between two fences leads to the swimming pool car park (S/E).
