I've camped at Shades probably a half-dozen times because it is just around the corner from Clement's Canoes on Sugar Creek. Many of the trails are marked rugged, with some requiring ladders not unlike Turkey Run. Only taller. My experience with our kids has been the more difficult the trail, the less bored they become....and less they complain.
Again, it's a great place for a hike or camping....no inn at this park. It also offers a long backpacking trail and back country campsite. May have to try that!
We ended our get-a-way with a family canoe trip down Sugar Creek. My daughter's first time in a canoe. 20 minutes into the trip both kids wanted their dad as their partner. We were told to watch for an eagle's nest, but we did not find it.
I stared at a lot of rocks looking for river glass
