Trouble querying Overpass for footways in national parks

I'm trying to query Overpass for trails and paths within nature reserves. My query seems to work fine in some nature reserves but not others. I have been querying in Maryland, USA. Specifically, I have noticed that it does not work in either of these national parks: Catoctin Mountain Park or Chesapeake and Ohio Canal National Historical Park. Can anyone tell me what I am doing wrong? Here's my query:

One Answer:

nature_reserve as ways are automatically converted to 'areas' in Overpass' database. Unsure if it's intentional, but relations aren't. Add map_to_area; to force a conversion

https://overpass-turbo.eu/s/1ua9

wr[leisure=nature_reserve]({{bbox}});
map_to_area;
wr[highway~"^(footway|path|track)$"](area);
out geom;
