Top 10 Most Popular Illinois State Parks by Number of Visitors

Honorable Mention – Moraine Hills State Park | 800K Visitors


Opened in 1976, Moraine Hills State Park has one of the only undeveloped glacial-fed lakes in Illinois leaving a pristine natural lake for fishing, hiking around, and boating! Under two hours from Chicago, this park is a popular destination for anyone looking for a little peace from the urban noise.

In 2020, Moraine Hills saw a burst of popularity, helping it leap into the top ten list from #13 in 2019 as a new entry into the most popular Illinois state parks list. Unfortunately, that didn’t last into 2021 and they have now dipped back down to their #13 rank. This just means you’ll have an easier time getting a campsite at least!

Giant City jumped up to the top ten list this year but is still a few hundred thousand visitors from their 1.2M count in 2019. They’ve been undergoing some construction in the last couple of years, likely contributing to the swings in attendance.

4. ( 4) Kankakee River State Park | 1.3M Visitors


Nestled along the beautifully scenic Kankakee River, the Kankakee River State Park offers something for everyone. It’s no surprise that Kankakee River is in the top ten most popular state parks in Illinois. Last year, they saw an explosion of growth, likely driven by the long-awaited reopening of the Potawatomi campgrounds after five years of construction.

Enjoy fishing for smallmouth bass, catfish, walleye, and Northern pike. Check out Rock Creek for a great angling spot or bring your boat to fish out on the river! If you’re looking to experience the captivatingly stunning nature this park has to offer, be sure to try canoeing down the river or camping for a weekend!
