Gretna Theatre, nestled snugly under the trees of Mt. Gretna since 1927, is one of South Central Pennsylvania's only professional theatres. Using professional, Equity actors alongside the best local talent, they produce a mix of Broadway musicals and comedies, musical revues, theatre for children and more each summer. Their covered, yet open-air pavilion-style venue seats 708 and lets in the summer breeze. They offer educational outreach programs in several counties throughout the year.
