Start from the car park on the edge of the Longeville Forest, at the end of a small road leading off the D25d.
(S/E) Take the Himering forest road heading north-north-east.
(1) Take the first track on the left heading west-south-west. Continue along the track. It climbs steadily up to elevation 311.
(2) Once you reach the 311-metre mark, take the track on the right heading north-west. This track descends and then climbs again to the 325-metre mark. Then take a track on the left, heading west-south-west, and follow it to the 302-metre mark.
(3) At elevation 302, take the path heading west, which climbs gradually up the hillside. Pass close to the Source des Lièvres.
(4) Take a path marked with a Yellow Disc, heading uphill towards the north. Follow the markings to the junction with the Himering Forest Road.
(5) At the junction, turn right towards the east onto the Route Forestière de Himering. Ignore the paths branching off to the right; pass the first junction you took on the way out.
(1) Return to the starting car park (S/E).
