Information:   Calleva is a self-supporting 501(c)(3) educational non-profit.  Every October, we hold a special event (benefit performance) known as Markoff's Haunted Forest (MHF).  MHF is essential to the achievement of Calleva's mission.  Due in large part to the income generated by MHF, Calleva is able to hire the best instructors and guides, purchase top quality equipment, and transportation to the area's best venues for climbing, rafting, kayaking, mountain biking and other outdoor adventure sports.

Markoff's Haunted Forest:

  • Gets people outdoors for a 20-minute hike in the woods surrounding Calleva Farm, a haunted hayride around the farm and/or a canopy tour with 5 zip lines & 3 bridges high above the forest.
  • Provides leadership opportunities for the young adults & teens who comprise Calleva's fall & summer staff.
  • Offers additional entertainment & activities that enable participants to stretch their comfort zones and achieve personal success.
  • Generates income to support all of Calleva's year-round programming, including: school programs, working students & after school programs with Calleva's horse center, summer camp scholarships, discounted programs and pro bono work, community partnerships with organizations including Girls on the Run of Montgomery County, Montgomery County Linkages to Learning, Potomac Riverkeeper, Team RiverRunner (Wounded Warriors).

"Markoffs" is Maryland's original and greatest Halloween event. There is so much going on that you're sure to soil yourself! Choose from 2 terrifying trails, a haunted hayride, a canopy tour and a dozen other spine tingling events. The Markoffs have been freaking patrons out for 20 years, and every year it gets a little crazier! Often copied, never duplicated -don't be a chicken, come walk through our woods!
