Need to Know
The Heron Rookery Trail follows along a portion of the Little Calumet River that once featured over 100 Great Blue Heron nests. After 60 years of nesting here, the herons have moved on to new nesting grounds. These woods remain alive with dozens of birds including kingfishers, woodpeckers and a wide variety of migrating and nesting warblers.
In spring, before the trees leaf out, the woodlands along this trail are blanketed with the most extensive display of spring wildflowers in the national park. Trillium, spring beauties, and Dutchman’s breeches are just a few of the flowers you’ll see along this trail. Most years, the wildflowers peak from late April through mid-May.
