Our GPS said 6.6 miles, not 5.8, There were two places where the river/swamp covered the trail and we had to try and walk around. Deep enough that if you don't have waterproof boots your feet will get wet. As another reviewer wrote, we heard lots of gunshots on the purple trail. Be careful transitioning from the Perimeter Trail (orange) to the Broad River Trail (purple). The park map does not show it accurately. We walked right past it until we consulted the AllTrails map, which is accurate. Enough ups and downs to get a good workout.
