Idlewild has just opened full time for the summer season, and with that comes the new Wowabunga Family Wave Pool, which replaced a nearly 80-year-old swimming pool. NPN has some great photos from the old pool here.
According to this article, the park is expecting half a million visitors this season. Park spokesman Jeff Croushore said that the Wowabunga addition is "the single-largest capital improvement project in Idlewild's history" and costs in the "multimillion-dollar" range. Along with the wave pool, Idlewild is expanding its entertainment offerings with "Cirque Extreme - Under the Big Top," featuring jugglers, a contortionist, and even trained cats and dogs!
Having a look around the park's website and park map, it's evident why Idlewild has bragging rights to "Best Kid's Park in the World" by Amusement Today and "#3 Best Park for Families" by National Amusement Park Historical Association.
