Joinerville Park is a 6. 5-acre day-use facility located about 4 miles west of Maquoketa on the Maquoketa River, serving as a major recovery point for paddlers.

The park features a concrete boat ramp (with the lower portion undercut by current), gravel parking, and is the last official access before Lakehurst Dam, making it ideal for shorter paddling trips or as a takeout point.

ADA-accessible parking and improved fishing areas are available at this popular river access.
