Skokie Trail is a 16.8 mile out and back trail located near Skokie, Illinois. The trail is primarily used for walking, road biking, and mountain biking and is accessible from April until October.
My family and I ride this trail often and have been for many years. It is very scenic and offers a lot of shade through the forest preserve if you go on a hot day. You do have to cross several streets, but overall, not too bad.
