Markoffs is Maryland’s original greatest Halloween event. There is so much going on that you’re sure to soil yourself! Choose from 2 terrifying trails, and while you wait, indulge in a dozen other spine tingling events from zip-lines to zombie hunts. The Markoffs have been freaking patrons out for over 20 years, and every year it gets a little crazier!


The haunted forest is put on by Calleva Inc. In 1993, the Markoffs started the Haunted Forest in order to raise money to start a summer camp. Calleva is now a year-round outdoor school committed to teaching and building strong leaders through positive outdoor experiences. Thanks to the many great staff, friends, and family that have made our dream a reality.
