Created by the minds behind the state’s most infamous haunts, we offer a one-way descent into your best – and most horrifying – Halloween experiences yet.
Nightmare Cleveland is a high-intensity, fully indoor haunted house located just outside the city in Parma, Ohio. Crafted specifically for horror fans who want more than just a casual spook, we deliver an immersive experience that pushes the limits of traditional haunted attractions.
Each timed entry allows guests to move through the space without long waits or overcrowding, building tension and realism to a new level. Tickets are limited, and you must purchase them in advance if you want a chance to live through your worst nightmares.
