Heintooga Round Bottom Road allows you to find solitude in the Great Smoky Mountains National Park, the nation's busiest national park. The trail travels downhill for over 16 miles and provides a forest view with glimpses of the Smokys for brief moments. The top two-thirds of the route is one-way only before you level out, and then the road becomes two-way travel while parallelling the Straight Fork Raven Fork River. No camping is along the road unless you have reservations for the Round Bottom Horse Camp.
