Birders will enjoy seeing flying critters that are not usually seen in the city. The flora in the marsh areas is quite interesting. You can get to the edge of the river and have a nice view of the Peoria skyline. The trails are flat, with several boardwalks. It stretches from behind Jonah's to Spindler Marina. The floods have caused some damage, but a lot of work has been done to make it a very pleasant walk. It is flat, so it is not a difficult walk. In the past, I have wandered through Spindler campground and continued north to McCluggage bridge. Lot of construction by the bridge now, so I haven't even tried this year. I have never seen it crowded.
