This 4.1-mile loop on the south side of Allerton Park and Retreat Center tours two of the park’s interpretive trails. Beginning at the Buck Schroth Interpretive trailhead, this counter-clockwise loop cruises dense upland woods laden with silver maple and shagbark hickory and skirts a bluff above the Sangamon River—allow a few extra minutes for tracing side trails to the shoreline.
In spring, wildflowers such as jack-in-the-pulpit and Virginia bluebells line the trail as it swings away from the river and joins the Blue Trail at mile 1.25. The loop’s western edge rolls through lush hickory- and maple-blanketed forest and crosses several intermittent streams before turning east back to the Red Trail. Near loop-end, you’ll skirt one of Illinois’ oldest restored prairies before backtracking a few hundred yards to the trailhead.
