Heron Rookery Trail
Phone: (219) 395-1882
For more than 60 years, herons nested here along Little Calumet River. Though the heron rookery is no longer active, the 1.6-mile trail is a good spot for viewing other bird species. The oak savanna habitat near the abandoned rookery is also home to Karner blue butterflies, federally listed as endangered. National Lakeshore resource managers conduct prescribed burns to maintain open savanna habitat. In springtime, the woods along the trail are carpeted with wildflowers, including trillium, Dutchman's breeches, hepatica, and mayapple.
