River Loop

The River Loop at Indian Cave State Park follows the Missouri River bottomlands through a lush corridor of old-growth cottonwood forest that provides one of the most atmospheric and wildlife-rich hiking experiences in eastern Nebraska. The trail begins at the river access area and winds along the floodplain terrace above the Missouri's main channel, threading through massive plains cottonwoods whose trunks reach diameters of six feet and whose canopy towers sixty feet overhead. The river itself is visible through gaps in the vegetation, its broad, silty current carrying the agricultural runoff of the Great Plains toward the Mississippi far to the south and east.

The bottomland forest supports an extraordinary diversity of neotropical migratory birds during May, when the dense leafy corridors channel warblers, vireos, tanagers, and thrushes moving north along the Missouri River flyway. During breeding season, yellow-billed cuckoos call from the dense undergrowth and red-headed woodpeckers work the snag-rich forest. White-tailed deer are ubiquitous, and the park maintains a significant population of wild turkey in the bottomland forest. The loop climbs briefly from the floodplain to a bluff overlook partway around the circuit, providing an elevated perspective over the river and the Iowa cornfields beyond. Mosquitoes can be intense in the bottomland forest from June through August; insect repellent is strongly recommended. The Missouri River bottomlands are also prime habitat for the fox snake, a large, harmless constrictor sometimes encountered on the trail.
