  • Hydra The Revenge is named after the nine-headed monster of Greek Mythology.
  • In the myth, Hydra battles the hero Hercules, who succeeds in cutting off all of Hydra’s heads. However, one head is immortal and Hercules buries it under a huge boulder by a lake. In Dorney Park mythology, Hydra has risen from Dorney Park Lake and takes its “revenge” on Hercules, the wooden roller coaster that the park retired after the 2003 season. Hydra The Revenge is located in the same spot bordering Dorney Park Lake where Hercules once stood.
