Mingo Falls - Cherokee Indian Reservation, North Carolina
Take HWY 441 to Big Cove Road drive about 5 miles to Mingo Falls Campground (large gray sign) turn right, cross bridge and the parking lot is straight ahead. You climb over 150 steps and walk a short foot trail over rocks to the wooden bridge.
Overall height of falls is 180 feet.
Note: you can photograph the falls without the use of Neutral Density filters. The speed of the water falling allows for a much shorter shutter speed. But, I highly recommend a good tripod.
