Introduction to the Halloween season: During Halloween every October, the Dinosaur Park will launch a night park for about a month. Different haunted houses will be presented every year, and after dark, there will be a group of demons dancing wildly. In the 2013 Halloween month, Dinosaur Park has four new haunted houses: Haunted Dinosaur Mountain, Psychedelic Cave, Walking Dead Prison Break, and No. 14 Medical Research Institute.
