Sometimes you’re so excited about visiting a particular attraction that you can blow it out of proportion. You can’t wait to make it to your destination and you plan an entire family weekend around it. It isn’t until you get there that you realize there just isn’t that much to do. Sure, it had some of what you hoped, but realistically, you can only fill a couple of hours and suddenly the rest of your weekend is wide open. This is certainly not the case at Pere Marquette State Park in Grafton, Illinois. With over 8,000 acres to explore, you’ll find plenty of sights and activities to fill your visit at this Illinois State Park.
