The Silver Comet Trail is located 13 miles northwest of Atlanta, Georgia and travels west through Cobb, Paulding and Polk counties. This quiet, non-motorized trail is for walkers, hikers, bicyclists, roller bladers, horses, dog walkers, and is wheel chair accessible. The Silver Comet is paved for over 37 miles starting at Mavell Road in Smyrna to Water Street in historic downtown Rockmart. When completed, the Silver Comet Trail will start in Smyrna, Georgia and end at the Georgia / Alabama state line.

At the Georgia / Alabama state line, the Silver Comet will connect to the 33-mile long Chief Ladiga Trail that ends in Anniston, Alabama. When construction on the Silver Comet and Chief Ladiga is finished, the trails will join to form one continuous trail from Smyrna, Georgia to Anniston, Alabama. The Silver Comet and Chief Ladiga Trails will connect in 2002.

Both the Silver Comet and Chief Ladiga are converted rail-trails built on abandoned railroad lines.
