For this one : https://www.openstreetmap.org/way/1013530888 there is clearly no signs that allow foot or bicycle: https://www.mapillary.com/app/?pKey=929616568649525

Theres also some others illegal path comming from the Hippodrome (fortunely not mapped) ; some of them are blocked by guards,  some countour them etc ... 

i propose to make a review of path conerned (already mapped but wrongly taggued )in this area and then make the change. 

I propose also to add more documentation here : https://wiki.openstreetmap.org/wiki/WikiProject_Belgium/Sonian_Forest

And add the tagguing sheme for illegal path and also a link to the presentation of sonian fondation they made last year (i don't recall the name of the osm events but it was here : https://www.openstreetmap.org/relation/3473319)
