From the center of Durham, follow RT 108 south for 1.5 miles and then take a right onto Bennet Road. Stay right at all "Y" intersections and follow Bennet Road all the way to the end where it intersects Packers Falls Rd.
Popular swimming place in the river behind Hancock Campground. Very large swimming area. Aka "Upper Ladies Bath". Park in the parking area after you get through the camping area. Walk back into the camping area #47, look for sign saying "RIVER"
There are two swimming locations here, both with signs that say "Swift River": One is across from campsite #60, the other across from campsite #49. The first is deep but has little beach, the second one is shallower but has a better beach.
