Terry Hill Water Park is now offically defunct. Probably has been for 2 years ATLEAST now. I went once when i was younger, it was alright. It was mostly body slides and a pool. The lazy river barely moved you, you had to like paddle yourself through it. They had ONE really fun tube slide that i remember.. The whole entire park is still standing with a for sale sign at the front of the park on rt 222.
EDIT:
http://www.terryhillwaterparkpa.com/home.htmlThe site claims theyre reopening for the 2013 season, but seeing NO WORK being done at the park, and the state the park is in... id really be surprised to see it open this year. Also.. I definitely wouldnt go because it doesnt look safe either.
