(S/E) From the Folon Foundation car park, head south-west and continue on foot along Chemin de la Ramée until you reach the end, 200 metres from the car park.
(1) Turn right onto Drève Joséphine. You will then follow part of theGR®126(Brussels - Membre-sur-Semois) trail, which winds along a stream, until you reach Drève de la Meute.
(2) Turn right and continue for about 700 metres until you reach a star-shaped crossroads. Then turn right onto Chemin de la Longue Queue to enter the Solvay Estate.
(3) Immediately turn left onto the small path (caution: this section is hillier and muddy in wet weather – you can take a shortcut by continuing straight ahead on Chemin de la Longue Queue).
When this path reaches the edge of the estate, take the path on the right that runs alongside the wooden fence and crosses a field of ferns. It then leaves the fence, veering off to the right, before arriving at a meadow. Follow the path on the left at the edge of the meadow and enjoy the beautiful view of the castle.
(4) Further on, you will rejoin Chemin de la Longue Queue, which you take on the left, towards the castle.
(5) Near the castle, take the path on the left that leads to the Etang de la Longue Queue, which you will walk around almost entirely before turning left to go back up towards the castle and around it. Facing the castle (west terrace), admire the obelisk at the end of the grassy clearing. Also take a look at the small garden to the left of the castle.
(6) After the castle, turn left onto the path that descends towards the Clos des Campanules. Then turn right at the hairpin bend and continue to the Folon Foundation.
(7) Go around the buildings on the left, then head straight ahead to go around the Etang de la Ferme and return to the car park (S/E).
