said: Waldameer is one of Pennsylvania's fabulous historic parks. It features 4 roller coasters, the oldest of which is the Comet (serial #117), 1951. The Comet is an ACE Coaster Classic designed by Herbert Paul Schmeck and built by PTC. The newest coaster is Ravine Flyer II, a hybrid (steel structure) built by The Gravity Group, LLC in 2008. The Ravine Flyer 3 is a family coaster built by Miler Coaster, Inc., and the Steel Dragon is a Maurer Sohne Xtended S 2000 featuring spinning cars. Other major thrills include the Mega Vortex and X Scream. Overall, a fantastic park for the family with a wide variety of rides. Be sure not to miss the Whacky Shack, a two story dark ride!
