By far, most of Stekoa Creek runs through private property. However, the last mile and a half ( approximately) before it joins the Chattooga River, is on National Forest land. There are two nice waterfalls on the upper part of that 1.5 miles. See my hike to the lower falls here https://mtnimages.smugmug.com/Hiking-With-Mtnimages/Lower-Stekoa-Creek/ This hike describes a continuation of that hike to the upper waterfall. Just after the lower waterfall comes into view there is a feeder stream coming in on the left.
