Coon Island Conservation Area offers walk-in access to a 3,223-acre wetland area along the Black River Ditch in southeastern Butler County, requiring no reservation or permit drawing.

The area features multiple parking lots with boat ramps and primitive camping in designated areas, though boating is restricted to designated waters and boats cannot be left unattended overnight.

Visitors should contact the Otter Slough Conservation Area office at (573) 624-5821 before visiting due to fluctuating water conditions from frequent river flooding.
