DISCOVERY DAY CAMP… DISCOVERY IS THE DIFFERENCE SINCE 1984! Located in the Lincolnshire / Vernon Hills area, Discovery is a summer day camp for girls and boys ages 4-14. It is a place where campers experience Adventure, Creative and Performing Arts, Swimming, Team and Individual Sports, Special Events, and so much more! At the core of everything we do, Discovery is an environment where campers and staff feel safe, comfortable, and happy.
