Rock Island is centered around the Great Falls, one of the most spectacular waterfalls in Middle Tennessee. About 80 miles east of Nashville, the park has two major trailheads. The first, right off of the main road, provides access to the gorge via a flight of stairs; you can then walk through the gorge and see the falls at a distance, although structures associated with the hydroelectric plant there do obscure the view.
Still, the beauty of the gorge and being able to walk up the bed in low water are worth a stop there. From the other trailhead, which can be accessed by driving across the dam at the entrance to the park and following a gravel road for a mile and a half, is in the gorge directly across from the falls. Although the views from both parts of the gorge are beautiful, if you don't have much time, I'd go to the trailhead right across from the falls, as it offers the best views of the falls themselves.
