Lake in the Hills Fen | Where’s Wildlife

Water beneath the landscape

Dry hills beside a living wetland

From the trail, the view moves between grassy rises, colorful flower stands and lower areas threaded with water. The photographs reward both ways of looking: take in the wide panorama, then pause for a flower, a perched bird or a Monarch among the blooms.

The Illinois Department of Natural Resources describes a landscape of limestone-gravel ridges surrounding high-quality wetlands. Water passing through sand and gravel takes up minerals from the limestone, then seeps out near the bases of hills to support fens. This mineral-rich groundwater helps create plant communities very different from those on the dry prairie slopes above.

The wider preserve includes gravel prairie, sedge meadow, marsh, shrub fen and other wetland communities. Its diversity makes “fen” more than a name for one patch of water: the surrounding hills and the water moving through them are part of the same story. Read the Illinois DNR nature-preserve description.

The conservation area and adjoining state nature preserve have different boundaries and access points. Use marked public trails and current maps, and leave sensitive wetland vegetation undisturbed.

Before you go

A prairie walk with time to look closely

Start at Jefferson Street

The conservation-area entrance is at 1500 Jefferson Street, Lake in the Hills, Illinois. MCCD lists daily hours from sunrise to sunset, subject to closures. Check the official site page and trail maps before leaving.

Trails & overlooks

MCCD lists 1.3 miles of trails, including mowed hiking routes, with a picnic shelter and scenic views. Allow extra time for photography: the images show how much there is to notice along even a short stretch of path.

Accessible viewing options

MCCD describes paved surfaces extending from the parking area approximately 300 yards in three directions, offering different views across prairie, sedge meadow and wetlands. A shelter and restrooms are also listed. These paved approaches are distinct from the mowed prairie trails. See official accessibility information.

Other access & preparation

Illinois DNR also describes nature-preserve access from Barbara Key Park on the Pyott Road side. Choose the entrance for your intended route. Bring water and sun protection for the open landscape, and footwear suited to grass and potentially damp ground. Follow posted restrictions and stay on designated paths.

The district incorporates native-planted rain gardens and bioswales into the site’s stormwater design. Protecting water quality is especially important in a landscape whose wetland communities depend on groundwater.

Through Brian’s lens

Prairie trails & open views

Green paths weave between tall flowers, stone seats offer a place to pause, and open water catches the light below the grassy hills. Select a photograph to open the slideshow.

Wildflowers & prairie grasses

Blue flax, prairie smoke, cream gentian, rough blazing star and wild bergamot bring very different shapes and colors to these photographs. Look beyond the petals, too: ground cherry’s papery husks, rattlesnake master’s rounded heads and the hanging spikelets of sideoats grama are small details worth stopping for.

These photographs record plants from Brian’s visits rather than a promise of what will be flowering on any particular day. Bloom times and the appearance of the prairie change through the season.

Birds among the stems & branches

A Henslow’s Sparrow sings from a dry seed head, a Cedar Waxwing perches in an evergreen, and a hummingbird visits purple flowers. These are moments from Brian’s visits; wildlife sightings will vary. Bring binoculars, pause to listen and watch from the trail without approaching or disturbing birds.

Monarchs & smaller discoveries

Monarchs appear on several different flowers, including rattlesnake master and blazing star. A striped beetle, pale moths and a frog blending into the grass show how much of a place’s wildlife can be easy to overlook. A slow walk leaves more room for these discoveries.
