Because it’s watered throughout, the Hennepin provides an excellent source of flatwater paddling. As DNR indicates there are 29 miles (46.7 km) of flatwater portage-free paddling in the feeder canal as well as shorter sections between the locks in the main canal section (see also Canal Facts tab on this website). (See the Illinois Paddling Council's website as well as Chicago paddling for additional information.) While the locks and some of the bridges need to be portaged on the Hennepin, they are never that difficult given the easy access of the trail.

This blog weighs in on topics such as long-distance skating, the Illinois canals, cycling, and a variety of related (and occasionally not-so-related) topics. I'd like to correspond with others interested in skating the Hennepin and I&M canals.
