Haunted Mansion is a track ride in Thrill Rides at Knoebels. While it's not the best, it is also recommended.
A classic haunted house dark ride, built in-house by Knoebels in 1973. This ride features old-fashioned amusement park haunted effects using lighting, timing, and stage-craft to create thrilling scares. But, like much at Knoebels, the quality of the work and maintanance on the ride is top-notch, so the whole is definitely greater than the sum of its parts.
