DifficultymoderateThe 11-plus-mile distance, I-43 rapid complex, boulder gardens, private banks, and access exposure make this more than a casual flatwater run.
PermitsNone notedNo route-specific paddling permit is known. Use the named public accesses, follow Wisconsin boating/PFD rules, and obey county park, road-shoulder, and private-property postings.
CampingOptions nearbyTreat this as a long day route. No designated on-route campsite is selected between North Union and the public access; use separate Manitowoc-area lodging or campground reservations rather than informal bank camping.
SeasonApr-OctThe lower Manitowoc is most dependable in spring and after moderate rain. Avoid scraping lows, storm spikes, and flood-borne debris, and use the lower access only after verifying current park conditions.

Access, shuttle, and map

Paddle the longer lower-Manitowoc continuation from North Union Road to the Mill Road public access. This is a committed day with the I-43 rapid complex, boulder gardens, private banks, water-quality caveats, and a direct-gauge floor rather than an invented upper cutoff.

Access caveats and watch for

Access caveats

  • MRW lists North Union Road and Manitowoc River Public Access as downstream water-trail sites, and Manitowoc County identifies the river access west of the County R bridge.
  • Miles Paddled publishes GPS for the Mill Road public access and cautions that the lower access can be poor depending on water level.
  • North Union has limited roadside parking; the Mill Road access has park-style support but should still be checked before the shuttle.

Watch for

  • A nearly mile-long Class I-II rapid and boulder-garden area around I-43, especially at higher whitewater flows.
  • Low-water scraping below the selected 250 cfs floor, fresh strainers, bridge debris, and fast rises after rain.
  • Private banks, limited exits, cold spring water, and manure-runoff water-quality concerns after storms.
