Kennywood Amusement Park, West Mifflin

This legendary old park is a National Historic Landmark, and one of the best amusement parks in the country. There are seven roller coasters -- some were built as far back as 1921, a fact possibly scarier than the rides themselves. The newest, Phantom's Revenge, was installed in May 2001. There's also the water rides, "flat" rides, and the haunted house. Don't forget the hot dogs and cotton candy! The park sometimes closes down for days at a time, so call or check the website to make sure it's open.
