Cobb County's Greenway Network: More Than Just the Silver Comet

The Silver Comet Trail gets all the attention — and it deserves it. But Cobb County's trail and greenway system extends well beyond the old rail corridor. A growing network of paved greenways, creek-side paths, and connector trails is quietly making Cobb one of the more trail-connected counties in metro Atlanta. Here is what exists and how to use it.

Cobb County sits northwest of Atlanta and is home to about 760,000 residents spread across a suburban landscape that is, in many places, not particularly friendly to people on foot or on bikes. The county's street network prioritizes vehicular movement on arterials; sidewalk coverage in many residential areas is incomplete; and the scale of development — large subdivisions, wide commercial corridors, shopping center clusters — is not organized around walkability. In that context, the county's trail and greenway investments are all the more significant: they represent a deliberate decision to build connected off-road infrastructure in a landscape that did not otherwise create it organically.

The Silver Comet Trail is the undisputed anchor. It runs 61 miles from its eastern terminus at Mavell Road in Smyrna to the Georgia-Alabama state line, following the former roadbed of the Silver Comet passenger railroad that served the Atlanta-Birmingham route from the 1940s through 1969. The trail is paved its entire length within Georgia, accessible year-round, flat to gently rolling along the old rail grade, and one of the most pleasant long-distance trail experiences available to Atlanta-area residents. The connection to Alabama's Chief Ladiga Trail at the state line creates a 95-mile continuous trail that is among the longest rail-trails in the Southeast.

The Cobb County Greenway system beyond the Silver Comet

Cobb County's greenway system — the collection of paved multi-use paths that the county has built alongside creeks, through parks, and connecting neighborhoods — now totals more than 60 miles of paved trail beyond the Silver Comet itself. These paths are less famous than the rail-trail and individually shorter, but they are the infrastructure that makes neighborhood-scale trail use possible — the everyday connection between a subdivision and a park, between a commercial area and a school, between residential streets and the regional trail system.

The Noonday Creek Trail in Kennesaw is one of the more complete of these greenway segments. It runs approximately 8 miles along Noonday Creek from the Silver Comet Trail connection near Whitfield Drive northward through Kennesaw and toward Bells Ferry Road. The trail passes through creek-side woodland for most of its length, with the canopy closing overhead in the mature bottomland sections. It connects to the Big Shanty Museum and provides access to the Kennesaw Mountain National Battlefield Park trail network on its northern end — a connection that links neighborhood-scale greenway to both a regional battlefield park and a nationally significant trail.

The Rottenwood Creek Trail connects the Silver Comet Trail's eastern trailhead area westward toward Cumberland and the Chattahoochee River, providing a paved connection through the dense commercial and residential fabric of inner Cobb County. The trail follows Rottenwood Creek through a corridor that is naturalistic in character despite the surrounding development density. Its connection to the Chattahoochee River National Recreation Area's Cochran Shoals and Sope Creek units on the north bank of the river makes it an important link in a potential cross-county trail route.

Kennesaw Mountain National Battlefield Park trails

Kennesaw Mountain sits in the center of Cobb County and is managed by the National Park Service as Kennesaw Mountain National Battlefield Park. The park's primary identity is historical — it protects the site of significant fighting during Sherman's 1864 Atlanta Campaign — but its trail system is also one of the most extensive in metro Atlanta, covering more than 20 miles of unpaved paths through the park's 2,965 acres of woodland and open terrain.

The mountain trails include the summit trail to Kennesaw Mountain's peak (elevation 1,809 feet, the highest point in Cobb County), routes along the original Civil War trench lines, and woodland paths through the forest that has regrown on former farmland and battlefield terrain. The reforested woodland now provides interior forest habitat that supports breeding birds uncommon in more fragmented suburban landscapes: ovenbird, wood thrush, and scarlet tanager are recorded in the park's forest interior during breeding season.

The park's trail network connects to surrounding Cobb County greenways via the Big Shanty Museum connector and a trail link to the Noonday Creek greenway, allowing visitors arriving from the Silver Comet Trail to reach the mountain summit via a completely off-road route from the Silver Comet's eastern sections.

Sope Creek and the Chattahoochee units in Cobb

The Chattahoochee River National Recreation Area includes several units within Cobb County. Sope Creek is the most ecologically interesting: a 12-mile trail network through creek-bottom forest along Sope Creek and its tributaries, ending at the Chattahoochee River. The ruins of the Marietta Paper Mills — nineteenth-century industrial ruins similar in character to those at Sweetwater Creek — sit on the creek bank and provide a historical dimension to the trail experience.

Sope Creek's trail network is unpaved, rooted, and considerably more physically demanding than the county's paved greenways. It is an appropriate destination for hikers comfortable with natural surface trails rather than casual walkers expecting a paved surface. The creek-bottom sections are slick after rain; the ridge trails above the creek are rockier and more exposed. The ecological character — mature bottomland hardwoods, clear creek water over sandy and rocky substrate, wood duck on the quiet creek pools — rewards the effort.

Using the system: practical connections

A serious trail user can now construct a full day of riding or walking entirely within Cobb County's greenway network, connecting the Silver Comet to the Noonday Creek Trail to the Kennesaw Mountain trails to the Rottenwood Creek Trail without using public roads for significant distances. That level of connectivity is not accidental; it reflects a county-level planning commitment to building the network as a system rather than a collection of unconnected segments.

The Cobb County Department of Transportation publishes a current greenway map showing all existing paved trails and planned future extensions. The map is available on the county website and at county parks facilities. Trail surface conditions after major rain events vary; the paved greenways drain quickly while the natural surface trails at Sope Creek and Kennesaw Mountain may remain muddy for a day or two.

For residents of Cobb County who have only used the Silver Comet, exploring the broader greenway network is a reasonable next step. For visitors from elsewhere in the metro, Cobb's combination of the Silver Comet, Kennesaw Mountain, Sope Creek, and connecting greenways makes it a destination worth a full day rather than just a transit point on the way out of the city.
