The stretch from Wilton to Ontario (12 miles) is seldom paddled, but is cleaner and faster than downstream legs. Those willing to endure weedy bridge accesses and occasional snags will be rewarded with spectacular outcrops. A very underrated part of the river.
The stretch from Ontario to Rockton (13.5 miles) is the most popular part of the river (if not the entire state). Highlights include spectacular outcrops. This section can easily be subdivided. Shuttle services are plentiful, but this leg can get crowded and noisy during summer weekends.
The stretch from Rockton to La Farge (11 miles) is the second most popular stretch of the river. While there aren’t as many outcrops as the Ontario Leg, the ones by La Farge tend to be larger and more impressive.
From La Farge to the mouth (~90 miles) very few rock outcrops remain. The Lower Kickapoo is more of a generic river paddle and few paddle it.
