Hydra The Revenge is a steel floorless roller coaster located at Dorney Park in Allentown, Pennsylvania, USA. It was designed by Bolliger & Mabillard and opened on May 7, 2005. Hydra The Revenge replaced a Dinn Corporation wooden roller coaster named Hercules, which closed in 2003. The ride features a heartline roll (or "Jo-Jo Roll") right out of the station.[1]


In September 2004, Dorney Park announced the addition of Hydra The Revenge.[2]

Hydra The Revenge opened on May 7, 2005.



The track is filled with sand to reduce the noise created by the roller coaster.[3]

The "jojo roll" at the beginning of Hydra was named after the park's Vice President of Maintenance and Construction, Joe Greene. Greene suggested the element on the ride.[4]
