Dorney Park & Wildwater Kingdom is a water park in Allentown, USA. The park opened on 1884, it features seven roller coasters, other adult and children’s rides, and a waterpark, Wildwater Kingdom. It features some of the world’s most prominent roller coasters, including Steel Force, the ninth longest steel roller coaster in the world and the second longest on the U.S. East Coast. The best ride here is Python Plummet and Steel Force. Other rides which I recommend you try are Thunder Canyon, Thunder Creek Mountain and White Water Landing.
