A nice Rails to Trails path, wide and made of concrete. In the Rockmart area the trail diverts from the rail bed and snaked through the town along the river and some industrial area where it is hilly but not impossible steep. Much of the trail is shaded and if you go east far enough enjoy the coolness of the tunnel.
A Rails to Trails project that is great for the biker. Concrete the entire way and no greater than a five degree grade, is perfect for biking. Well maintained and heavier traffic as one gets closer to Atlanta, it is connected to the Chief Ladiga trail that continues into Alabama for another 30 mile.
