The summer is not complete without a visit to one of PA's great water parks. Knoebels PA water park is great fun for the whole family. The waterpark's Crystal pool has all sorts of waterslides and diving boards for your summer pleasure. One of the best rides is Skloosh!, a 16-passenger rubber craft that gets carried up a steep incline and launched down a water ramp. There's even a water park just for your little ones, as they can swim around in shallow water, enjoy fountains, and much more. Once you're done cooling off at the water park, you can dry off at one of the many roller-coasters and other amusement park rides at Knoebels. Best of all, admission is free!
