For this hike, the easiest option is to park at the end of Avenue du Triangle, not far from Chaussée de Braine l'Alleud in Rhodes-Saint-Genèse.
(S/E) Head south to the end of Avenue du Triangle, then turn right onto Chemin des Sept Fontaines and continue along Chemin du Meunier, a large stone path that descends along the valley, until you reach the first crossroads after the small pond.
(1) Take the path on the left that passes between two ponds and continues to the right, following the large main pond that is now on your right. Shortly afterwards, a pedestrian chicane allows you to follow the bank to the end. Then follow the paved path on the right, leaving a higher pond on your left.
(2) After the large pond, another chicane on the left allows you to take a path that passes through a meadow, running along the right side of the small pond and the stream that feeds it. The whole area is partly hidden by trees. A small bridge crosses this stream a little further on. Continue along this path, which joins a roughly paved road.
(3) Turn right. This path passes in front of the huge Ermitage farm, which is currently being renovated (see "Nearby" section below), then climbs between meadows and a private wood. This is the Colipain drive.
(4) At the top, turn right onto Chemin Lazard. Continue along this straight path and, at the Y-junction, keep right, leaving Chemin du Bois du Vicaire on your left.
(5) Take a small path that descends to the right. This path is not very visible in autumn, hidden by dead leaves, but it becomes more obvious further on, turning into a sunken path. Further still, it joins meadows at a T-junction.
(6) At the bottom, turn right onto the path called "Kwademarasch", which is also part of the Grande Randonnée hiking trail. Watch out for the barbed wire on the right as the path becomes very narrow. Continue until you reach the main pond.
(7) Turn left to reach the initial fork.
(1) Continue straight ahead, still following the ponds, and join Avenue du Triangle (S/E).
