Silver Comet Trail: A Practical Guide for Cyclists and Walkers

Sixty-one and a half miles of paved, car-free trail on a former railroad bed — the Silver Comet is one of the best outdoor assets within reach of Atlanta. Whether you are riding a full day end-to-end or walking a few miles near a trailhead, here is what you need to plan a trip.

The Silver Comet Trail follows the former right-of-way of the Seaboard Air Line Railroad's Silver Comet passenger service, which ran from New York to Birmingham before the line was abandoned. The corridor was acquired and converted to trail use in stages beginning in the 1990s, and the Georgia section — from Smyrna in Cobb County to the Alabama state line near Cedartown — opened fully in 2008. At the state line, it connects to Alabama's Chief Ladiga Trail, making a continuous paved corridor of more than 90 miles accessible to anyone willing to drive to a trailhead.

What makes the Silver Comet exceptional as a regional trail asset is its combination of length, grade, and surface quality. Because it follows a railroad grade, the trail's elevation changes are minimal — the steepest grades are gentle enough to be comfortable for casual cyclists and for riders on cruisers and hybrids rather than performance bikes. The paved surface is well-maintained along most of its length. And the corridor, running through a mix of forest, farmland, and suburban edges, is largely shaded, making it considerably more comfortable in Georgia's summers than an exposed path would be.

Key trailheads and access points

The eastern terminus at Mavell Road in Smyrna is the most heavily used access point and the starting point for most day rides out of the Atlanta area. Parking is available and the trailhead has basic facilities. From Mavell Road, the trail runs west through a series of suburban and rural communities with trailheads offering parking and, at some locations, water and restrooms.

Powder Springs, roughly 13 miles from the Smyrna terminus, is a convenient turnaround point for a moderate out-and-back ride of about 26 miles — a comfortable half-day ride for most cyclists. The downtown Powder Springs area near the trail has food options for a mid-ride stop.

Rockmart, at roughly 35 miles from Smyrna, sits near the midpoint of the Georgia section and is a reasonable turnaround for longer-day riders or a good starting point for people driving from west of Atlanta who want to ride a portion of the quieter rural section. The trail through Polk County beyond Rockmart becomes more remote, with fewer services but correspondingly less traffic.

The Alabama state line terminus at the Cleburne County line is marked with a small monument and connects directly to the Chief Ladiga Trail. Riders doing the full Georgia section as a point-to-point trip need a vehicle shuttle — leaving a car at the western end and driving to Smyrna, or arranging pickup. Some local cycling clubs organize supported point-to-point rides that handle logistics.

What to expect on the trail surface and conditions

The paved surface on the Silver Comet is generally smooth enough for road bikes with narrower tires, though some sections show weathering and patching that may be more comfortable on a hybrid or gravel bike. The trail is wide enough for two-way traffic in most sections, and the grade is consistent and gentle — a few shallow cuts through small hills, some open timber bridge crossings over creeks and roads, and long straight sections through forest corridors.

Tree canopy covers much of the trail, particularly in the forested sections between communities. This shade makes summer riding significantly more bearable than it would otherwise be, though the late-morning and midday hours on exposed sections near communities can still be warm. Early morning starts are strongly recommended for warm-season riding of any significant distance.

The trail is shared by cyclists, walkers, runners, and people on inline skates. Trail etiquette — announcing when passing, yielding to pedestrians, keeping right — applies throughout. The mix of users is generally cooperative, but group riders on weekends should be aware that the trail carries significant foot traffic near trailheads and at community access points.

Wildlife and natural landscape along the route

The Silver Comet corridor passes through a landscape that includes second-growth forest, creek crossings, farm edges, and several notable trestle bridges over lowland areas. These environments support a range of wildlife visible from the trail with reasonable frequency. Wild turkeys are common in the more rural sections of Paulding and Polk counties. White-tailed deer are seen regularly along forest edges, particularly in early morning and evening. Red-tailed hawks and other raptors hunt open sections of the corridor.

The creek crossings and low trestle sections are good places to look for great blue herons, green herons, and kingfishers working the water below. Box turtles occasionally cross the trail in warmer months — worth watching for on the road surface, as they move slowly and are hard to see at cycling speed until you are close. Eastern box turtles are a species of conservation concern in Georgia due to road mortality and habitat loss; giving them safe passage off the trail if you find one in a hazardous position is a worthwhile two-minute stop.

Planning a day trip from Atlanta

From central Atlanta, the Mavell Road trailhead in Smyrna is approximately 20 to 25 minutes by car depending on traffic. Arriving early on weekends — before 9 a.m. — secures parking and avoids the midday crowds. Riders planning longer distances should carry more water than they think they need, as fountain access is limited between communities in the rural sections. A basic repair kit — tubes, tire levers, a pump or CO2 inflator — is worthwhile for any ride beyond 20 miles.

The Silver Comet is dog-friendly, and leashed dogs are common on the trail. Keep dogs on a short leash and to the right edge of the trail when other users approach. Equestrian use is not permitted on the paved surface but is allowed on adjacent unpaved corridors in some sections — check current rules at the trailhead before bringing horses.
