The Dark Forest opened in March 2010; replacing UG Land which opened in 1999. Dark Forest is themed as a supernatural area of woodland that has been disturbed by recent excavation of an ancient burial ground.
Among the three main attractions are Crypt Games. The new ride for 2010 was unveiled as TH13TEEN, a steel sit down partly indoor coaster themed as a haunted crypt. It features the world's first freefall drop on a roller coaster, and a drop into total darkness.
