Gragg Prong Dispersed camping is at the beginning of the Gragg Prong Falls/Huntfish Falls trail parking area. There are numerous dispersed sites near here - one right down from the main parking and a few on the other side of the bridge.

If you hike about .25 miles on the trail there are is also another great campsite. Reminder that dispersed camping means NO AMENITIES so please pack out any trash and leave the area better than you found it.

There's also a nice little swimming hole near the parking lot that is pictured. I can't imagine that it is highly visited since it is very out of the way from the mainstream areas.
