City Surfers is an after school and summer program in East Harlem and Inwood. Youth will decide what they would like to learn, which health issues they would like to address, and how to alter their physical environment to improve their health. Programs are built around their needs and interests. They will build a movement of youth who live to play outdoors. 3,000 Upper Manhattan children will participate annually in a monthly outdoor health leadership training series. Teachers will receive support to become health advocates in the classroom and at our sites.
