Tucked along the Illinois River in Marshall County, Marshall State Fish & Wildlife Area sprawls across 6,000 acres of bottomland forests, marshes, and managed wetlands near the town of Lacon. Established in 1925, it’s one of Illinois’ oldest wildlife areas and remains a cornerstone destination for hunters, anglers, and birders drawn to the Illinois River valley.

The area’s mix of backwater lakes, sloughs, and timber stands creates prime habitat for waterfowl, making it a top spot during fall duck and goose seasons. Deer hunting is equally popular, with both archival and firearm seasons drawing steady crowds. Outside of hunting, anglers work the river backwaters for largemouth bass, channel catfish, and crappie, particularly productive in spring when floodwaters recede and fish concentrate in shallow pools.

Birdwatchers will find Marshall rewarding year-round. Great blue herons nest in the bottomland timber, bald eagles patrol the river corridor in winter, and spring migration brings waves of warblers and shorebirds through the wetlands. Several miles of trails and levee roads offer easy walking access into the heart of the property.

Fall is the standout season here — the waterfowl migration peaks, hardwoods turn gold along the river bluffs, and the air finally cools after Illinois’ humid summers. Spring runs a close second for fishing and birding.

With a solid 4.2-star rating from visitors, Marshall delivers an authentic Illinois River experience without the crowds of better-known state parks. Come prepared for muddy conditions and bring binoculars.
