Amusement Dark is a collection of interactive dark rides located within Cedar Fair amusement parks. There are currently two operating attractions, Wonder Mountain's Guardian at Canada's Wonderland which opened in 2014, and Voyage to the Iron Reef at Knott's Berry Farm which opened the following year. For both dark rides the audio visual components were designed by Triotech Amusement.
