JCC Maccabi Sports Camp, together with three others opening their doors this summer, is part of a growing Jewish specialty camp trend that is picking up steam around the country. Since the first set of specialty camps launched four years ago — an arts camp in Manhattan, an environmental-themed camp in the Poconos, two wilderness camps, one based out of Atlanta, the other in the Rockies, and a sports camp in North Carolina — nearly 3,000 Jewish tweens and teens have enrolled. For more than a third, according to one report, it was their first Jewish camping experience.
