At Sippenaeken, the route runs on an asphalt path at Le Vieux Moulin campsite. On the border B/NL there is a large boulder that you can drive past. Path is paved for about 300 meters but can be a bit muddy after a rainy period. At the end of the path, turn right and immediately turn left of the road onto the asphalt strip. From the junction at Hoeve Termoere, the route is easy to ride again.
