Founded in 1926, Waldemar is a beloved all-girls camp set in the Texas foot hills along the Guadalupe River. It’s stunning. And so popular that it’s hard to get into it—this is going to sound crazy, but parents actually sign their kids up when they’re born. Every girl is a member of a tribe, and earns points for her tribe throughout camp for everything from good manners to field day victories (on the final day, a tribe winner is announced). The girls live in stone kampongs, which is a South Sea Island word for a house on stilts. And activities are divided into water sports, land sports, and the arts. Girls between 4th and 11th grade can attend one of Waldemar’s two month-long sessions. There is also a shorter, one-week term for girls entering 2nd through 5th grade.
