Summer Xtreme is the alternative the middle school age group has been looking for, and once they become part of the Summer Xtreme experience, your middle school child will be coming back for more, week after week! Middle school students are too old for the traditional town programs, but they still need to keep active. We offer thrill seekers, artists, social butterflies, athletes, and laid-back boys and girls this remarkable option to meet new friends while engaging in fun activities. Activities are on-site and off-campus for special adventure days, giving these campers more freedom. Our program encourages building friendships, independence, self-control, and the ability to make safe choices and good decisions all while having fun and building self-confidence!
