A donation of 100 acres (40 hectares) of farmland created the only national park dedicated to the performing arts. Given along with the land were the funds to build a 6800-seat indoor/outdoor theater. From May through October, Wolf Trap is home to a variety of performances - everything from classical music and jazz to rock 'n' roll, opera and theater. On warm summer evenings, it is popular to come early and bring a picnic. The park also includes The Barns at Wolf Trap - a year-round performance center and a Children's Theatre-in-the-Woods.
