Starved Rock State Park
Starved Rock State Park is open daily at 7:00 am, so we like to add this on the way to the Wisconsin Dells or Chicago. Just a warning -- the waterfalls are only active in the spring or after heavy rains.
Tips and observations:
Even if you only have an hour, it's great to park at the Visitor center, as there are quite a few trails under a mile. (Click here for the trail map)
The Visitor Center is open daily from 9:00 am to 4:00 pm.
If you want to make it a full day, they have 13 miles of trails to explore, and the Illinois River offers fishing, boating, extraordinary views and great places to relax.
