There seems to be some confusion. Ripley's Believe It or Not! is a museum chain known for its exhibits of oddities and unbelievable stories. While Panama City Beach does have a Ripley's Believe It or Not! museum, there isn't a waterpark directly affiliated with Ripley's in the area. However, Panama City Beach offers a variety of exciting waterparks, including Shipwreck Island Waterpark. Perhaps you were thinking of this popular waterpark that boasts thrilling rides, a relaxing lazy river, and a wave pool, all perfect for a fun-filled family day.
