Have You Discovered Volo Bog?


In the west of Lake County lies one of Illinois’ unique natural communities, Volo Bog. Managed by the Illinois Department of Natural Resources, Volo Bog State Natural Area contains a few trails for you to explore including a half-mile interpretative boardwalk and an approximately three-mile trail with views of the tamarck forests. In 1970, Volo Bog was designated as an Illinois Nature Preserve and in 1972 as a National Natural Landmark.

Over 10,000 years ago, during the end of the last Ice Age, a chuck of retreating glacial ice lodged itself deep in the ground at what is now Volo Bog. Several thousand years later the remnant lake began to fill with salt and vegetation, creating the wetlands present today. Volo Bog is technically known as a quaking bog because vegetation floats atop the open water. Yes, all the surrounding plant life and trees in the picture above are floating. Over time, the absence of waves will allow the plant life to slowly expand further onto the water, eventually covering the entire site.

As you explore this natural area, you’ll quickly transition between several types of habitats, including tamarack forests, marshlands, and shrublands. If you’re a photographer or just an avid Instagrammer, bring your camera or phone and share what you find at Volo Bog!

Interpretive Trail

Getting There

Volo Bog is little over an hour’s drive from downtown Chicago. There are several road routes across Lake County to reach Volo Bog, and the site is accessible on Brandenburg Road, just north of the intersection of IL-120 and US-12. Be sure to swing by the visitors’ center when you arrive to get some more information and you can plan on packing lunch as there are multiple picnic areas at Volo Bog.

The Eye of Volo Bog

The center of Volo Bog is called the Eye, and it is far more than a simple, ordinary pond. The Eye of Volo Bog is the only remaining open-water quaking bog in Illinois and the southernmost quaking bog in North America to show all the stages of bog succession.

From a birds-eye view, Volo Bog looks like a eye (hence the nickname maybe?), with five distinct layers of vegetation surrounding the ‘pupil.’ Each of the five rings support different varieties of plants and each marks different durations of time that plants have expanded over the open water. The three inner-most rings, made up herbs and shrubs, are floating on water that’s 50 feet deep! Here you’ll see plants like white water lilies, water shields, and highbrush blueberries, as well as tamarack and bog birch trees. You may even notice a scent of peat in the air.

As you walk the boardwalk, keep an eye out for the changes in plant life that you pass, and the signage along the way will point out some of the unique features.
