The Quiet Upgrade Season: What's Actually Changing at East Cobb's Parks and Trails This Fall

Most fall guides for East Cobb read like a printout of the county events page. Chalktoberfest, HarvestFest, a 5K or two, a parade. What those roundups miss is that the season's best moments aren't scattered across a map. They line up along a single geographic spine, and that spine is being reworked underfoot right now.

If you already live off Johnson Ferry, Paper Mill, or the Roswell Road corridor, this is the season your daily walk actually changes.

The Spine Runs From Paper Mill to Jamerson

Draw a line from McFarlane Nature Park at the Paper Mill and Johnson Ferry intersection, up through East Cobb Park at 3322 Roswell Road, across the East Cobb Trail sidepath along SR 120, and out toward the future Noonday Creek expansion near Jamerson Road. That's the corridor. Almost every fall event with a local pedigree, and every capital project the county is currently working on in this pocket of Cobb, sits within a mile or two of it.

That is the argument of this post. The fall calendar is not a menu of unrelated outings. It is a season that runs along a set of parks and trails you already use, and several of those parks are being quietly upgraded before the leaves turn.

East Cobb Park Is Getting Slate Swapped for Pervious Paving

The most useful fact in the county's June 2026 SPLOST status report, if you walk East Cobb Park regularly, is a single line: portions of the slate trail are being replaced with pervious paving. The project is in the Planning phase, which means the ground you're walking on now is not the ground you'll walk on next spring.

Pervious paving matters here for a specific reason. East Cobb Park is a 20-acre passive park with playgrounds, five pavilions, an outdoor stage, and a walking path that hugs Sewell Mill Creek. The slate sections have always been the pinch point after a heavy rain. Pervious surface lets water through instead of pooling, which is the kind of small change that stops being invisible the first weekend it rains and your shoes stay dry.

The adjoining work is already done. The county lists the "add slate to trail from East Cobb Park to Robinson Rd" project as complete, which finishes the through-line between East Cobb Park and Fullers Park across the Sewell Mill Creek bridge. Fullers is the active counterpart. It has the gym, the tennis courts, the ball fields. East Cobb Park is where you go to sit. Walking from one to the other in a single loop is now the closest thing East Cobb has to a signature short trail.

McFarlane Just Earned a Credential Most People Don't Know Exists

In May, McFarlane Nature Park was awarded Level 1 Accreditation by the ArbNet Arboretum Accreditation Program and The Morton Arboretum. Read past the press release and here's what it means for you: the 11.5 acres tucked half a mile from Johnson Ferry and Paper Mill now sits in the same registry as botanical gardens around the world.

The park is quietly extraordinary. Every native tree species of the Georgia Piedmont region is represented on the property except two that only grow in the mountains. Fourteen separate species of Quercus, the oak genus that supports more other living species than any other kind of tree, live within the fence line. The 280-foot perennial border along the entry drive is maintained by the Master Gardener Volunteers of Cobb County. Bee hives are active. The 1940s farmhouse is still standing.

McFarlane runs on donations. There is no government funding line, no admission fee, and the gate is open every daylight hour of the year.

That combination — a nationally recognized arboretum, no admission, and a five-minute drive from Whole Foods at Merchants Walk — is not something you get in most suburbs.

The Bigger Trail Ambitions Are Still On Paper

Both of the priority trail projects in the county's Greenways and Trails Master Plan for our side of Cobb are unfunded. That is worth knowing before you get excited about a ribbon cutting.

The Noonday Creek expansion is the more complicated one. Much of the proposed corridor sits in floodplain or floodway, it would cross three major roads, and a signalized crossing at New Chastain Road is part of the concept. If it happens, it happens slowly. The Hyde Farm alignment is cleaner because most of the route runs through public land, utility easements, and existing road right-of-way, but it also has no dollars assigned.

You can walk the existing East Cobb Trail today. It's 2 miles of paved sidepath on the south side of Roswell Road, running from Manor Crest Court east past East Side Elementary and Indian Hills Parkway toward Seven Springs Circle. The Bethlehem Primitive Baptist Church Cemetery is a worthwhile stop about halfway across. Traffic on Roswell moves fast, so cross at signals.

The Fall Dates That Actually Live On This Spine

Here is where the geographic argument pays off. Sort the fall calendar by proximity to the spine and the pattern is obvious.

• Saturday, August 8, 7:00 a.m. The Rotary Club of East Cobb's Dog Days 5K, a 21-year tradition, still opens the season.
• Saturday, August 8, 9:00 a.m. to 2:00 p.m. Pope High School Band's Community Recycling Day at the NE Cobb Family YMCA. Paint, metal, electronics, appliances, and paper shredding on site, $15 per car plus disposal fees where applicable. If you have been sitting on a garage full of old monitors, this is the drop-off.
• PopeFest 2026. Pope High School turns 40, so the school's own festival scales up this year with live music, food trucks, and a fireworks finale. Dates are being finalized on the East Cobb Area Council calendar.
• Saturday, October 3. The 28th annual East Cobber Parade & Festival. The parade runs one mile south on Johnson Ferry Road from the Princeton Lakes subdivision entrance at 1223 Johnson Ferry to Olde Towne Parkway, and the festival lands at the south parking lot of Johnson Ferry Baptist Church, 955 Johnson Ferry Road, from 11 a.m. to 3 p.m. This is the closest thing East Cobb has to a hometown parade, and it runs directly through the spine.
• Second weekend of October. Chalktoberfest at Marietta Square, presented by the Marietta-Cobb Museum of Art at 30 Atlanta Street. More than 80 chalk artists and 40 breweries. Admission is free, beer is not.
• Third Saturday of October. HarvestFest on the Marietta Square. Same walkable footprint as Chalktoberfest, different weekend.
• Late October. The Cobb PARKS Fall Festival of Fun at Jim R. Miller Park, 2245 Callaway Rd SW, from 5 to 9 p.m. Free admission, hayrides, inflatables, a haunted house. This is the county's answer to a school carnival.
• Marietta Square, morning race. The Make-A-Wish 5K, a Peachtree Road Race qualifier, benefits Make-A-Wish Georgia and starts at the Square.

Add the Cobb PARKS Haunted House, the Cobb County Library Fall Book Sale, and Sprayberry Trunk or Treat and you have a Saturday-by-Saturday season without leaving a 15-minute drive of your front door.

A Weekend Worth Building From Scratch

If you want a single Saturday that captures what's actually new this fall, try this sequence. Start at McFarlane on Farm Road for a slow morning walk under a canopy of labeled native trees, then drive ten minutes north to East Cobb Park for a mid-morning loop across the Sewell Mill Creek bridge into Fullers. From there, the parade route on Johnson Ferry or the Chalktoberfest booths on the Square are both a short hop, depending on the weekend.

This is a route you couldn't have built the same way two years ago. The Fullers connector wasn't finished. McFarlane wasn't accredited. The East Cobb Park slate had not been slated for replacement. The pieces have been assembled quietly, one project at a time, while everyone was reading the same recycled fall bucket list.

The parks and trails you already use are getting better. The events you already attend cluster on top of them. Pay attention to the spine and the season plans itself.
