The Trails/Parks Committee of the River Corridor Coalition has videos of the entire river route broken into seven segments, along with an interactive map to help identify where the segments are. Visit crosscitytrailduluth.com to check it out. This is the lesser known route that is harder to find and understand, so be sure to check it out.
The city wants your input, so go to the survey and participate. This is a regionally significant trail connection, connecting two great state trails, the Munger Trail and Gitchi-Gami Trail. When all is complete you can go from Hinckley to the Canadian border.
