The 3,750-acre Clarence Cannon National Wildlife Refuge is located in Pike County in the floodplain of the Mississippi River. Although it is protected by a levee, the refuge provides flood storage in periods of high water. The refuge is managed by Great River National Wildlife Refuge.
Hunting is not allowed at Clarence Cannon except for a couple of managed hunts. In early Spring, you might see bald eagles and large flocks of snow geese and Canadian Geese, as well as other waterfowl.
There are no marked trails, but lots of gravel roads to walk along.
Directions. From St. Louis, take I-70 west to the Highway 79 exit. Take Highway 79 north approximately 35 miles to the town of Annada. In Annada, take County Road 206 East one mile to the refuge office.
