Illinois is full of natural wonders and prehistoric monuments, some of the most fascinating examples are found in our caves and mounds.

Head down to Cave-In-Rock State Park in southern Illinois, where a massive riverside cave carved into the limestone cliffs has captivated visitors for centuries. Once rumored to be a hideout for river pirates, but don’t let that dissuade you from visiting, this site now offers a scenic and safe peek into the state’s rugged past.

A bit farther north, Illinois Caverns State Natural Area near Waterloo is one of the few public wild caves in the Midwest. With its underground streams, mineral formations and cool year-round temps, it’s a true adventure for nature lovers and geology buffs alike.

Above ground, Illinois is home to some of the most important Native American archaeological sites in the country. At Cahokia Mounds, just outside of St. Louis, you’ll find the remnants of a massive city that once rivaled London in size. It’s a powerful reminder of the Mississippian culture that thrived here long before European settlers arrived.

For a more intimate experience, Dickson Mounds offers insight into Native life along the Illinois River. Its museum and trails overlook the valley, once home to generations of Indigenous communities.

From underground to prehistorical heights, these sites offer an immersive way to connect with Illinois's natural and cultural history.

Although historic accounts regarding the origins of deep dish pizza differ, the consensus holds that the birthplace of deep dish pizza was in Illinois. Chicago, now home to iconic chains and local restaurants, is where deep dish was invented at Pizzeria Uno on 29 East Ohio Street.

Did you know there is a 3,000 mile long road that follows the entirety of the Mississippi River? This scenic route winds all the way from Lake Itasca in Minnesota, to Louisiana and the Gulf of Mexico. Of all the territory the road covers, Illinois has by far the most picturesque stretch of the river.

Pro tip: the stretch of River Road between Alton and Grafton Illinois is unlike any other place in Illinois. This area is the confluence of the Mississippi, Missouri and Illinois Rivers. Complete with a full view of the Mississippi and towering white cliffs, you would hardly think you were in the Midwest. There are many memorable stops along the way including the Loading Dock, Pere Marquette State Park, Lewis and Clark Confluence Tower, and Historic Downtown Alton.

Today is National Popcorn Day and a perfect way to celebrate is to enjoy this classic treat as your state snack! National Popcorn day may have popped up on the National Holiday calendar in 2013, but this time-honored snack has been celebrated since 1988. From a traditional movie theatre food to a gourmet sweet, popcorn is a national and local staple.

With approximately 333 popcorn farms across Illinois, the state is recognized as the third largest grower of the product. In 2003, this “Official Illinois Snackfood” was voted as a state symbol thanks to the support of second and third grade students and their teacher, Fran Hollister, at Cunningham Elementary in Joliet, which was sponsored by former State Senator Larry Walsh.
