The Haunted Forest of Maple Valley is a mile-long indoor/outdoor attraction held in the haunted trails of the Maple Valley Royal Arch Park. The Forest is produced by Haunted, a 501 (c)(3) non-profit, whose “soul” purpose is to give back to the community. Proceeds benefit local youth groups like DeMolay, Girl Scouts of Western Washington, Jobs Daughters Int’l, Boy Scouts, Venture Crews, a variety of Masonic Lodges, Eastern Star, and many other charities.
