Nashville's Stones River Greenway travels about seven miles from the Cumberland River to the J. Percy Priest Reservoir, parallel to and occasionally within sight of Stones River. The trail connects a number of communities and parks including the skate park at Two Rivers Park where I began. This trailhead is adjacent to The Wave Country waterpark, just off Route 155 (Briley Parkway) and about a half mile south of the Grand Old Opry, Opry Mills, and Opryland Hotel complex.
The trail is paved and in very good repair. It was April and foliage was nearly in full bloom, making for a very scenic ride. The trail is not a former rail line so steep grades and a one-half mile long uphill will get your heart pumping.
Boardwalks and bridges protect fragile environmental areas and drainages.
Here's a photo of the namesake Stones River.
If you head left onto the trail from Two Rivers park, the trail takes you below the freeway and its ramps and then over the adjacent Cumberland River on the Pedestrian Bridge and gets you to Shelby Bottoms Greenway and another five miles of paved trails.
