Depends where you want to be... so here's a few suggestions that we like.
Kankakee State Park just off I57 (South side of the city)
Illinois State Park by Zion Il. (North side of the city)
Indiana Dunes State Park (only 45 min from downtown) also if here you can take the South Shore (train) and leave the truck and traffic behind
theres a quick 3 spots
