From/To Place Joseph Hallaux, 1390 Grez-Doiceau, Belgium. Spacious parking at the station.
Based on an idea from Pierre Becquart. I tried to combine his 2 favorite routes starting from Gastuche to make a few more kilometers. About 90% unsurfaced.
Attention: from Florivalstraat follow Direction knppt 242 and not the GR! This is a nice climbing hollow road. At km 6.3, don't worry about private access. People sometimes have trouble with motocross riders, who constantly cross the language border so they can't be caught. You walk through a nice little valley and then almost turn 360° to follow the GR.
You can shorten the route by returning directly to the starting point at km 9.
