Heron Rookery Trail

3.3 miles, 12 feet of elevation gain, 0% average grade, 1% maximum grade
Hike time: 2 hours

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.

The featured hike starts from the east parking lot. The hike is a simple out and back. Follow the trail from the east parking lot to the west parking lot and back. The trail surface is packed dirt and clay, which can make this trail very slippery when wet. Wear adequate footwear.

In late April to mid-May, before the trees leaf out, the woodlands along this trail are blanketed with the most extensive display of spring wildflowers in the national park. Fishing is also popular during the spring and fall when salmon and trout are making their spawning runs from Lake Michigan into the Little Calumet River. Indiana state fishing regulations apply.
