The Ozark Wildlife Area encompasses much of the scenic 4. 4-mile paddling stretch between 21st Ave and 60th Ave on the North Fork Maquoketa River, featuring steep Driftless Area bluffs, recessed limestone cliffs, and large boulders.

The 21st Ave access point (off 185th Street) provides a muddy but doable put-in with a public pull-off and trail, while the 60th Ave take-out on the east shore offers public access, though the removed bridge complicates logistics.

This segment is best paddled in fall or spring when leafless trees reveal the dramatic rock outcrops that are otherwise hidden by summer vegetation.
