The Tennessee River Gorge Segment consists of two linear sections, Signal & Edwards Points and Poplar Springs, and two loops, Mullens Cove and Pot Point. Together, these sections make up 33.8 miles of trail currently open, but only the 6.9 miles of the Signal Point Section are considered part of the official Cumberland Trail.
The Poplar Springs Trail connects the CT to the figure-eight of Mullens Cove and Pot Point loops. The trailhead for Mullens Cove is on Tower Drive.
Highlights of Mullens Cove include spectacular, high overlooks of the Tennessee River Gorge and a natural rockhouse and stone door.
