Take 321 to Cosby Entrance Road, then stay straight into the campground. Park at the Nature Trail and follow it to the Low Gap Trail. Once on the Low Gap Trail in will be on your first bridge crossing.
Heavy rains had brought Cosby Creeks water levels up and cloud cover allowed me to capture the entire scene in a beautiful neutral light. This was taken along the Low Gap Trail in the Cosby Campground section of the Great Smoky Mountains National Park.
