Brantwood Camp Brantwood Camp, a summer camp for boys and girls, enrolls campers who are between the ages of 11 and 15 from Boston, New York City, Jersey City, Hartford, and urban areas of New Hampshire who might not otherwise have an opportunity to attend summer camp. Since 1904, boys have enjoyed our active, residential summer camping experience surrounded by the beautiful hills and woods of Peterborough, NH. In 1982, we opened Brantwood for Girls a mile away. Every summer, Brantwood serves 365 campers, with each camp offering three 16-day terms. Campers are recommended and sponsored by social service agencies, schools, churches, and a variety of youth organizations.
