I believe the paths are only default accessible to cycling, as they are path=yes. They do not have the tag, bicycle=yes, or any other mode of transport. 

I do however take exception to your tone, and demand that I do mapping to fulfill your wants. Please feel free to make edits to the map, it is open source. And finally, yes, if you had looked, there are dozens of GPS tracks of mine within the perimeter of the memorial Park.
