Cub Scout Pack 657 is made up of first grade through fifth grade boys, mostly from Hopkinson Elementary School. Boys meet in small groups (dens) of 5 to 10 boys. Each den has an adult leader, and consists of boys in the same grade. First graders are Tiger Cubs, second graders are Wolf Cubs, third graders are Bear Cubs, and fourth and fifth graders are Webelos. See Ranks and Advancement for more information about these.

Pack 657, together with other Cub Scout packs and Boy Scout troops make up the Orange Frontier District. The Orange Frontier District is one of 11 subdivisions of the Orange County Council. There are over 300 councils in the United States.
