1. Cahokia Mounds, Collinsville

Located directly across the river from St. Louis, Missouri, the Cahokia Mounds State Historic Site features about 80 mounds constructed between 900 and 1400 A.D. Cahokia was a great city until the inhabitants mysteriously abandoned it sometime around the early 15th century. Monks Mound, the largest remaining mound, features four terraces, and rises 10 stories high. Each mound served specific functions in the society of Cahokia, including burials. This historical gem helps visitors understand the early civilization of the area.

2. Mississippi Palisades State Park, Savanna

Cross over into another world when you enter Mississippi Palisades State Park. Put on some good walking shoes and hit the trails once traveled by Native Americans who followed the bluffs along the Mississippi River. Along the rugged 15 miles of trails, look for the many limestone caves that feature stunning rock formations, including Twin Sisters. Help the kids watch for and identify the various species of wildlife you encounter, including deer, skunks, foxes, squirrels, and birds. Visit during spring, summer, or fall as some overlooks and amenities close during winter months.

3. Cave in Rock State Park, Cave-in-Rock

Pirates, and bandits, and outlaws, oh, my. If anyone knows where to find a hidden treasure, those guys do–and, in 1739, a French explorer found the cave and named it “caverne dans Le Roc.” River pirates used it as a base camp, and other lawbreakers followed suit. Things changed in the mid-1800s when a church moved into the cave, and established their village nearby, which they later named Cave-in-Rock. Find the cave, kick back, and relax in peace and quiet.

For a relatively easy hike that is suitable for all ages and skill levels, hit the jackpot when you find this treasure tucked away in a mature oak, hickory, and beech forest. Water passing over an outcropping of sandstone carved out a natural bridge that is 90 feet long and about eight feet wide in places. Stay on the trail and just a few yards downstream you find a small cave.

Silver Creek and Stephenson Railroad’s pride and joy is the 1912 Heisler steam locomotive that carries passengers on the 3.4-mile round-trip ride.

8. Grosse Point Lighthouse, Evanston

Step off the beaten path and keep stepping all the way to the top of the 1873 Grosse Point Lighthouse. Take your kids who are ages eight and older on a scheduled tour to climb the 141 stair steps to the top of the tower for a stunning panoramic view of Lake Michigan. Docents lead tour groups on Saturdays and Sundays, June through September.

9. Villa Kathrine, Quincy

Few people know there’s a beautiful castle–Villa Katherine–hidden on a bluff overlooking the Mississippi River in Quincy. A wealthy Illinois native, W. George Metz, enjoyed European architecture and decided to build his mansion in 1900. He lived alone there until selling the property in 1912, after which it changed hands several times before becoming the town’s visitor center. After picking up tourist information and touring the castle, feel free to tour Katherine Villa Park, overlooking the river.
