Loved it, Packed! with birds singing and chirping :). About 1/2 of the trail is in the open/in the sun. The trail map will show the trail as green, the trail markers are actually yellow tho.. maybe just really faded. The 'scenic overlook' (aka old landfill) in only open to go up Sat/Sun 11-6. So i'll have to make another trip for that view. Not to upset about that.
Well maintained trail. There are two main loops, one very wooded and one out in the open. There are several options to create the distance you want to travel. It is a very flat trail. For a portion of the year, hiking to the top of a large hill provides great views.

I've walked this trail many times with my dog. This trail is also a great little cross-country ski trail in years when it snows. There are several options available as far as trails. The DuPage Forrest Preserve has maps in the parking lots.
