Knock Knolls is a pretty park, but it is spectacular in late April and early May. That's when the forest floor is carpeted with Virginia Bluebells. If you get to experience this, you will never forget it. To get to the bluebell area, cross the bridge over the DuPage River from the parking lot. After the bridge, there is a dirt path on your right. Follow this back into the woods. Most of the bluebells are a beautiful lavender blue shade, but if you're lucky you'll spot some white and pink ones. Enjoy your time here!

Visited Knoch Knolls Park in Naperville one August afternoon. The place is wonderful for outdoor enjoyment. There are many opportunities to keep oneself active here. We walked on the beautiful trails crossing over the DuPage River on two beautiful bridges. The trails are lovely with shade from interspersed. The paved trails are heavily used, but we did not see too many people on the unpaved nature trails. The trails are well marked. Lot of nice scenic places for photography. The Nature Center building and the surrounding prairie landscaping are very well done (did not go inside the building). There is an impressive children’s playground at the Nature Center. Other recreational opportunities include a disc golf course and kayaking on the river. The longer DuPage River Trail goes by Knoch Knolls park. There is plenty of parking. Knoch Knolls Park is a wonderful place to enjoy nature.
