Hennepin Canal Feeder Trail is a 31.4 mile out and back trail located near Rock Falls, IL and is good for all skill levels. The trail is primarily used for road biking and is accessible from April until October.
I was a little disappointed. We started in Rock Falls and went south, the further we went the more grown over it got and we only could go about 7.5 miles before the path was covered with canal water and was not passable. In the description it said it was used by road bikes, not likely!
This starts in my back yard! Easy gravel path for walking, running, biking, kayaking, birding... You name it, you can pretty much do it all.
