Markoff's Haunted Forest

Dickerson, MD

A 33-year Montgomery County institution ranked the top haunt in the world for 2025, run by a youth-program nonprofit.

Thirty-three seasons deep, Markoff's turns the Dickerson woods into the most acclaimed haunt on earth for 2025. The Forest trail bleeds into the Town and Onslaught Mills, where a new three-story castle wears props from a 1980 Black Sabbath tour. Every scream funds Calleva's youth programs.
