The main bridge on the lake trail is ADA accessable but the nature trails are not mainly because the tree roots and the smaller bridges all have a step up that might be to big for a wheelchair
The main areas, including the bridge, are wheelchair accessible. I couldn't be certain about any trails. Try contacting the local state park ranger service...
Not the ones I saw..may want to contact the park
I think if the smooth ones would be fine. Not the ones with tree roots.
