A few years ago Renee and I were in Gatlinburg and picked up one of those books that has things to see and do in the area. In the book Renee found a trail,not a walking trail,but one you could drive,that took you up and around the mountain.Water falls,beautiful scenery. The road was narrow so not sure driving a dually would be a good idea.Can't remember the name of the park,but as you drive out of Gatlinburg on 441 we tuened left.I know that is not much help,but like I said we found the park in one of those see and do books for the area.
