Hydra the Revenge
Site preparation began in late 2003, when on September 1, 2003, Hercules, a wooden roller coaster that sat in the current location of Hydra the Revenge, was closed and demolished. On September 14, 2004, the $13 million Hydra the Revenge was announced. Construction began in the spring of 2004 and continued through the winter. Hydra the Revenge was topped off (highest piece of the lift hill) on August 20, 2004 and the entire track layout was completed on December 4, 2004. The first cars for the coaster arrived at Dorney Park on December 10, 2004 and the first ride with people on a train took place on March 24, 2005. The roller coaster officially opened to the public on May 7, 2005.
