The Community Center (formerly Carthage Elementary School) houses the Seniors of Carthage and the Carthage Community Gardens. A fitness room is available for members. Carthage has two parks: Caldwell Playground and Caldwell Nature Center. The nature center has an amphitheater and 3.5 miles of nature trails. The playground features a spray park for the wamer months.
The Carthage Civic League is very active and meets monthly. Founded in 1937, it is one of the oldest community councils in Cincinnati. This group of citizens and business owners are in charge of neighborhood beautification flower pots along Vine Street, a Community Day, as well as other projects in the community.
