This a little out of the way and there really aren't signs to direct you but once you get here, you'll enjoy it. There is a nice visitor center with nice views of the area and a few displays. Outside, a nice walking trail through a small prairie down to the marsh and back up through the forest. I also rode the bike trail through the marsh. It follows the dikes so it's mostly flat and a pretty easy, enjoyable ride.
