Rafting and kayaking
The Illinois River is "a wilderness river that tests both the skill and strength of boaters". For the run along the Wild and Scenic part of the river between upper Oak Flat near Kerby and lower Oak Flat, boaters are far from trails and roads. In fact, it is "the most inaccessible river canyon in the lower 48 states..." with sections that are inaccessible, even by trail. Depending on the water flow, this stretch of the river has eight class IV to IV+ rapids. Green Wall, a class V, "is considerably more difficult and longer than the others" and below it lie of difficult rapids. The river is generally run by

, but the permit must also be deposited at Oak Flat to verify the safe completion of the trip. Since there is no dam on the Illinois River, river flows are highly dependent upon weather conditions. Changing weather can often result in water levels being too high or too low for safe and successful navigation. Furthermore, since water levels can rise rapidly, potential bad weather can also be the cause for cancelled or postponed trips. Nevertheless, even under acceptable conditions, the Illinois River can still cause casualties.
