Haunted Forest of Maple Valley: Shady Grove Asylum

All-volunteer nonprofit haunted house trail through Maple Valley's Royal Arch Park with an immersive asylum theme. Two experience levels: evening Full Fright runs (7–11 PM Fri–Sat) for adults seeking intense scares, and daytime Family Walk options (12–3 PM Sundays) with food trucks and community vibes—proceeds benefit local charities chosen by the volunteer team.
