The ultimate rollercoaster, TH13TEEN, launches on 20th March 2010.

TH13TEEN will be based on the discovery of an unearthed ancient burial site in an area of unexplored woodland known as the Dark Forest.

Built on the site of the old Corkscrew rollercoaster, visitors will be invited to take a petrifying ride on Thirteen, venturing into the seemingly living and breathing Dark Forest.

There they will face an unknown horror that has been unleashed from the ancient crypt.

The ride has been developed with the world's leading coaster and thrill consultants who have collaborated to combine the ultimate elements of physical and psychological fear - to create what experts are dubbing a 'psychoaster'.
