Cache River State Natural Area protects over 14,300 acres of ancient cypress-tupelo swampland in southern Illinois — a landscape that feels more like Louisiana bayou country than the Midwest. Established in 1970 near Belknap in Johnson County, this natural area shelters some of the oldest living trees east of the Mississippi, including bald cypress specimens estimated at over 1,000 years old.

The star attraction is the Lower Cache River wetlands, where massive buttressed cypress trees rise from tea-colored water draped in Spanish moss. The Heron Pond boardwalk trail offers the most accessible way to experience this ancient swamp, winding through old-growth forest to a stunning tupelo-cypress pond that peaks in autumn color. The Section 8 Woods trail leads through upland hardwood forest with wildflower displays in spring.

Birders come year-round for wading birds, migrating warblers, and wintering waterfowl. Paddlers can explore the Cache River by canoe or kayak when water levels cooperate, typically in spring. Hunting is permitted in designated areas during season. Fishing is available along the river and in backwater sloughs.

Camping information should be confirmed with the Illinois Department of Natural Resources before planning an overnight trip, as facilities and availability may vary.

Spring and fall deliver the best conditions — spring for wildflowers and high water levels ideal for paddling, fall for spectacular swamp color. Summer brings heat, humidity, and mosquitoes in force.

With a 4.7-star rating across 66 reviews, Cache River consistently rewards visitors willing to venture into Illinois’s deeply underrated southern tip.
