While the trails themselves are very clear, the trail names are no where to be found aside from the regional trail. You'll end up walking farther than intended if you aren't paying attn or don't have a sense of direction. Beautiful marshland and woodlands. Wasn't anything much to see in terms of wildlife, birds, or flowers, but to be fair it is February. We turned off too early on our way back to the car and ended up having to go through the maintenance station and Mack Rd. Trailheads aren't marked either except at the start. Wasn't a great way to end a beautiful walk. We will definitely go back in spring or summer as I bet it is teeming with flora and fauna.
This review is for McKee Marsh on the north side of the preserve. This is a prime location for birding in DuPage County, especially in the spring and fall when birds are migrating. Bring binoculars and a camera with telephoto lens, if you have them. Don't forget bug spray in the summer!
