I've been to this lovely campsite three times - once in the fall and twice during different summers. The campground and park are packed during the late fall as everyone around comes to see the colors. Find a campsite that's a little ways away from others if you want a more private experience - they're very close together but you can find ones with better tree cover.

Starved Rock is great because you can walk a mile or two in a loop or do the full "mega hike" which is 13.4 miles through 18 canyons. The park features lots of elevation with many sets of stairs so make sure you bring water, sunscreen and snacks.
