This is one of the most well-known sections of whitewater in the US. Section IV includes major whitewater, including Five Falls, a set of five Class IV-V rapids within 1/3 of a mile.
Large, paved parking lot, restrooms, trailhead, and an overlook of the Chattooga River. A short walk upstream lets you observe boaters take on Bull Sluice, a large IV+ rapid just upstream of the Highway 76 access.
Developed boat ramp with parking.
This is a serious whitewater section for advanced boaters. More information about running whitewater through this section can be found on the American Whitewater page.
There are a number of commercial rafting guides in the area if you want to experience the Chattooga River's classic whitewater.
