IL Posted in Illinois March 24, 2016 by Laura 11 Things You Must Do In Illinois On A Hot, Summer Day It’s almost summer, so we are definitely planning for all the amazing things we will do when it turns warm (for good). Here are 11 things you should do on a hot summer day in Illinois. 1. Lake Kinkaid Spillway Curtis Abert/Flickr This is the best swimming hole in Illinois. Head over to southern Illinois and let the water rush over you. Then, float in the deep pools. 2. Hurricane Harbor Six Flags Great America/Facebook Many people head to Six Flags on hot summer days in Illinois. But why not hit up Hurricane Harbor this time? Provided you plan well, you can hit both parks. 3. Grizzly Jack's Grand Bear Resort Grizzly Jack's/Facebook After a long day of hiking at Starved Rock State Park, come stay at this Utica hotel and relax in the beautiful pool. 4. Illinois Beach State Park Peter Ciro/Flickr Isn't this stunning? Walk 6.5 miles of beach alongside Lake Michigan. 5. Millenium Park Juan Carlos Martin/Flickr Kids love running through the fountains here during the summer. You might get a few looks, but adults definitely do it, too. 6. KeyLime Cove KeyLime Cove Indoor Waterpark/Facebook This indoor water park covers 65,000 square feet. The cool thing you'll notice right away about the hotel is that the slides go both inside and outside the hotel. In addition to the water, there is a place to eat and also an arcade, as well as other activities for the kiddos. 7. Rend Lake J Rend Photography/Flickr This 29 acre lake is referred to as southern Illinois' playground. People have loads of fun getting out on the water here and camping. 8. Go for a drive.
