Volo Bog State Natural Area

NOTE: The Volo Bog Interpretive Boardwalk is closed due to unsafe conditions until funding is secured for upgrades.  The first section into the marsh moat remains open. The other trails (5.5 miles worth) remain open. We apologize for the inconvenience and appreciate your support. 

If you're looking for a truly unique outdoor adventure, head for Volo Bog State Natural Area in Lake County in northeastern Illinois.  The site includes Volo Bog, the only quaking bog in Illinois, significant in that it exhibits all stages of bog succession. A floating mat of sphagnum moss, cattails and sedges surrounds an open pool of water in the center of the bog.

Local citizens partnered with the newly formed state chapter of The Nature Conservancy and mounted a fundraising campaign to purchase the bog in 1958.  The land was later deeded to the University of Illinois.  In the late 1960s, local citizens again advocated for Volo Bog to protect the site from proposed development, and encouraged its eventual transfer to management of the Illinois Department of Conservation, now the Illinois Department of Natural Resources.  The Friends of Volo Bog, a 501(c)(3) membership organization, formed in 1983 and has fought to protect the site from additional threats including bisection of the site by a proposed highway.  They continue to this day to advocate for the protection of Volo Bog and support programming and projects at the State Natural Area.

Volo Bog was dedicated as an Ill​inois Nature Preserve in 1970. Three years later, it was registered as a National Natural Landmark.  More than 1,100 additional acres of land have been purchased to protect and enlarge the state preserve, which now includes marshes, prairie restoration areas, woodlands, two other bogs, and scenic trails.

Originally opened in 1980, Volo Bog's Visitor Center is housed in a dairy barn built in the early 1900s.  Renovations began in 1996 to bring the building up to code, make it fully accessible and accommodate the needs of the fast-increasing population of northeastern Illinois. The center includes a program room, the Tamarack Shop, offices and restrooms on the first floor. An elevator, housed in the silo, takes visitors to the second floor exhibits, hands-on discovery area and library.

The Visitor Center is open Wednesday - Sunday from 9 am - 3 pm as staff and volunteers are available (and by luck and chance otherwise).  Phone 815-344-1294 to check daily availability.

A picnic area with tables and an outdoor privy is conveniently located adjacent to the visitor center parking lot. Visitors are encouraged to bring their own grill for cooking or use one of two near the picnic shelter. Ground fires and alcohol are strictly prohibited at Volo Bog State Natural Area.​​​​​​

Site Hours:

Gates open at 8:00 am 363 days a year - closed Christmas and New Year's Days

Closing time is posted as one enters the parking lot and as one walks out of the parking lot.  Closing times vary with the season; plan to be back to the parking lot no later than 30 minutes before sunset.  Closing time might be EARLIER than that so PLEASE make note of the time as you enter.
