Are you looking for another walking/hiking trail and to walk thru the woods and get away for a bit. Yes, there is undisturbed land that people don't want to see condos or businesses built on. Northbrook has done a fine job preserving this land and taking care of the grounds and the vistors center. There is an eagle and some other birds of prey located in outdoor cages. There is also some bee-keeping done on the grounds. How sweet is that!
