If you are accessing the park via 113, west of Route 45, there is an access road within the park. If you go to the opposite side of the street, there are a couple of entrances. Either way, head down to the cement boat launch. It was littered with charcoal from idiots who dumped their grill in or near the river.
The river was high, relatively fast and very muddy.
We took the kayaks out at Kankakee State Park, just west of Warner Bridge Rd
