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

The area features multiple parking lots with self-registration check-in stations, primitive camping in designated areas, and boat access, though water conditions fluctuate significantly with Black River flooding.

Visitors should contact the Otter Slough Conservation Area office before visiting due to unpredictable water levels and potential hazardous conditions when flooded.
