At an elevation of 7,192 feet, North Franklin Mountain is the highest peak in the Franklin Mountains. Couple that statistic with the fact that the route to gain the peak is a little less burly than the route to South Franklin, and you have a recipe for a busier trail. You still probably won't see a ton of other runners and hikers once you make it up to the ridge.
