I'm not buying the 7.1 distance, I am buying at least the 2100 feet in elevation change. We have what we did at nearly 12 miles. Plenty of chances to get in the water and to get different vantage points of the falls. we went down Dismal, then back up. Dismal had more switchbacks, some bouldering and three ladders and a ledge on the way back up to the payoff....a suspension bridge over the tallest waterfall in South Carolina. Challenging enough, not for a beginner or little one. Love it.
