Little Kids (5-8)

The program offers supervised outdoor camp activities and free play throughout the day. Camp Counselors will escort campers to and from their swim & tennis practices, clinics, and lessons so they have a safe transition and enjoy a variety of activities throughout the day in addition to camp.

Big Kids (9-11)

Wanting our “big kids” to have a space of their own, we have a “Chill Zone” with seating, shade, ping pong tables, board games and more. They have the freedom to move between the organized program and the Chill Zone as it interests them.
