The Arc’s mission is to help children with intellectual and developmental disorders cultivate their artistic talents and build life skills. In a semistructured environment, campers ages 5 to 21 attend two-week sessions that include activities such as arts and crafts, games, swimming, music, dance therapy, and field trips. Some of the campers’ artistic creations are later auctioned during public displays. Siblings are welcome, space allowing. Two-week camps are $525. Call for locations.
