Explore nature in Illinois before summer’s end. Trails for walking and biking are open at forest preserves and state parks. One special place is Glacial Park, less than an hour's drive from Northbrook in McHenry County.
Walk up small hills called kames, through tallgrass prairie and savannah woodland till you reach a large marsh. Sit quietly on the observation deck and notice frogs, turtles, dragonflies, and other marsh-dependent creatures quietly dipping in and out of the water. https://www.mccdistrict.org/visit___explore/places_to_go/find_a_site/glacial_park.php
