LaSalle County, Illinois
LaSalle County is a big stretch of land in north-central Illinois, where the Illinois River cuts through. Ottawa is the county seat, but Peru and LaSalle are in the mix too in terms of population. Starved Rock State Park brings in tons of hikers.
It’s old coal country, trying to find its footing these days. You’ve got a weird mix of industry and farmland here. Corn and soybeans are for miles, broken up by the occasional wind farm.
You’ll find some great old bars along the river, the kind of places that haven’t changed in 50 years. Buffalo Rock State Park is also nice if you want to avoid the Starved Rock crowds. On a good day, you can spot bald eagles soaring over the river.
