Get ready to venture off the tourist trail and unearth the hidden gems that make Illinois a captivating destination for those willing to seek out its secrets.

Anderson Japanese Gardens | Rockford

One of the highest-quality Japanese gardens can be found in northern Illinois and offers a slice of tranquility to visitors of all ages.

Cahokia Mounds | Collinsville

An Ancient Native American city in Southern Illinois? That’s exactly what visitors will find at this site — the largest Pre-Columbian site north of Mexico. The site covers over 2,000 acres and 72 of the civilization’s remaining 80 mounds, providing a fascinating glimpse into ancient North America.

Cache River State Natural Area | Belknap

Renowned for its ancient cypress swamps, Cache River is a nature lover’s paradise — home to over 100 endangered species and nearly a dozen state-champion trees that have stood tall for centuries.

History buffs looking to dive even deeper into ancient Illinois history will love this archaeological museum that offers insights into Illinois’ indigenous tribes.

Garden of the Gods | Herod

Short hikes, unique rock formations, and great views? That’s what visitors will be rewarded with after a quarter-mile hike in the Shawnee National Forest. Arriving at the Garden of the Gods, visitors can gaze upon the unique geological structure of the forest and appreciate a view of the forest that seems to go on forever.

Matthiessen State Park | Oglesby

While Starved Rock State Park is one of Illinois’ top outdoor attractions, Matthiessen State Park is no less scenic.

Keep your eyes peeled for abundant plant and animal life and round things out with a family picnic.

Kaskaskia Dragon | Vandalia

One of the best things about Midwest hidden gems is their uniqueness and the Kaskaskia Dragon is certainly unique. Constructed in 1995, this 25-foot metal monster actually breathes fire and has glowing red eyes each time a Dragon Coin is dropped into a special slot — coins are purchased onsite at a self-service coin box. Pull off of US Highway 40 and see this firebreather for yourself!

Bishop Hill | Henry County

Founded in 1846 by Swedish immigrants, the Bishop Hill Colony is now a historic site that invites visitors to take a step back in time.
