I hiked to Rainbow Falls on the west side of in Gorges State Park in Transylvania County, North Carolina. Note I only hiked to Rainbow Falls; there area couple more waterfalls if you stay on the same trail. Hike writeup to come at Two-Heel Drive
Rainbow Falls generates lots of mist -- if you get to close you'll get soaked if it's really pouring, like after a major rainstorm goes through. This is one of the most impressive waterfalls I've seen in North Carolina, though there are probably are even bigger, better ones I haven't seen yet.
