Discover the County
Cobb County
Established in 1832, Cobb County developed around communities with different histories and roles in the Atlanta region. Marietta remains the county seat, but the incorporation of Mableton changed the county’s municipal landscape: Mableton is now its largest city. Kennesaw Mountain preserves a nationally significant battlefield and landscape, while downtown districts offer other perspectives on local change. The county’s character includes historic places, suburban growth, recreation and major sports destinations. Those layers are best understood by exploring more than one community.
Choose a mountain walk, a downtown visit or a ballpark outing as the centerpiece of a day in Cobb. Kennesaw Mountain has specific parking and access rules, so consult the National Park Service before visiting. Marietta and the county’s other cities offer additional opportunities to explore. Event crowds can change travel conditions around major venues. Check official schedules, admission and transportation information when planning, and use county and city websites for resident services.
