Description of the walk

Park in the car park at Profondsart station.

(S/E) Take Rue de Rofessart and follow it until you reach Avenue de Nivelles.

(1) Turn right and then immediately left onto Avenue des Cerisiers. Continue for about 500 m until you reach No. 72 and turn left onto the path. At the junction with Avenue de Nivelles, turn right onto Avenue Boulogne-Billancourt.

(2) After about 50 m, turn left onto the Sentier de Ruhongo towards the Mare aux Loups. When you reach the small triangular square, turn left onto the Sentier de Trélon. 300 m further on, turn left onto Rue du Monastère and continue straight ahead at the roundabout.

(3)Take care when crossing the N275, which is a fairly busy road.
Follow the small road opposite which leads into the countryside. At the first junction, continue straight on along the footpath.

(4) You will reach the junction with the Ottignies road. Continue straight ahead. Atthe third junction, which is covered in poor-quality cobblestones, turn left down a slight slope. You will reach the junction leading to the Moriensart castle farm.

(5) Here you have two options:
_ extend the route by 400 m by turning right to visit this castle farm. In this case, at the castle farm, turn left along the car park, then 100 m further on, turn left again and 150 m further on rejoin the route by continuing straight ahead.
- otherwise, turn left and keep left at the next junction. Continue in this north-easterly direction until you reach the Chemin de Hayettes. Follow Rue du Réservoir to rejoin the N275.

(6) Cross it and take the street opposite. As soon as you reach this street, take the small slip road on the left into Rue des Vergers. Continue along this street until you reach the junction with Rue de Lasne.

(7) There, turn left uphill. Just after No. 19, turn right onto Chemin des Marronniers. At the junction with Rue du Charnois, turn left and, 30 metres further on, turn right onto Chemin des Bourdaines, which starts as a tarmac road and becomes a footpath after 50 metres. Follow the footpath down to the bottom of the Try, then head right here. 75 metres further on, turn left up Avenue Lambermont to the next junction.

(8) Turn right towards Rofessart Church onto Rue de Profondsart, which further on becomes Rue Elie Legrève. At the renovated old farmhouse on the left-hand side of the street, before the road bends right and heads downhill, turn onto the small dirt track. Access it by walking alongside this old farmhouse. This path leads back to Rue Legrève. You will soon come to Rue de Rofessart on your left. Follow it alongside the railway line until the route ends at the car park at Profondsart station (S/E).

Hike done on a grey day (with drizzle at the end).
Very accessible, the biggest climb is at the beginning, and after that it's very pleasant.
Beautiful views (I imagine they would be even more stunning in the sunshine )
Thank you for helping me discover the region :-)

Thank you for your comments.
It is true that since this walk was created, there have been changes to street names (Chemin de Bourgeois has become Rue de Rofessart).
A path has also been created through the fields where there was previously no access. This allows you to avoid the long tarmac road that cuts through the fields. I have updated the walk to include this new path, making the walk more enjoyable.

I have therefore updated the description and route of this walk to reflect the current situation.

Kind regards

The positives: easily accessible by public transport, quite rural (from point 3 to point 7) in a heavily urbanised area, and the Moriensart castle-farm is well worth a look. It’s odd that this detour is only an option!
Not so good: the description.

  • It lists street names, but there aren’t often any corresponding signs on the ground.
  • At the start, it’s not the Chemin des Bourgeois, but Rue de Rofessart that’s written on the sign in situ
  • From point 3 onwards, if you follow the map, you end up on a small road rather than a path
  • Between points 4 and 5, the route is entirely on road; there is no dirt track, whether it be the Chemin du Meunier or, after the crossroads, the Chemin de la Chapelle Robert
  • At point 8, the Chestnut Tree Path starts after No. 19 (or before No. 21), but not after No. 21.

After point 9, you need to take a path near an old farm. There are two: one before and one after. It is the one after that you must take, and it starts at the bend.

A very pleasant route at this time of year when it’s damp.
A correction to point 8: ‘just after no. 21’ should be changed to ‘just before no. 21’.

We’re certainly out in the countryside – it’s pretty, but there’s nothing particularly noteworthy.
Two-thirds of the route is on tarmac or concrete.
The elevation changes do not match my measurements.
Thanks to the author.
