I've renamed the “path” section of Vorstersstraat to Kasteelstraat (see https://www.openstreetmap.org/changeset/146602414), this is what GRB says and the situation on site does not contradict it.

So, from Kasteelstraat (the path part), I couldn't spot any path, but again, it's an unmaintained area with rubbish, dumped building materials, low shrubs and trees which have grown there etc. So same situation: a path might connect Kasteelstraat (path) with the marker, but it's not visible.

I didn't check the situation from Terstrekkes, will go back and check if I have the time.

I also didn't check whether a path started from Brugstraat because the last section of that street looked like a private driveway, so I didn't attempt to go through there.
