This giant obstacle course is a combination of giant slide and obstacle course. The pool, as seen in the photo, will be removed and the slide is for dry use only. This attraction is best suited for high volume events. Hundreds of participants can pass through the course in an hour. It is also a lot of fun to have speed competitions or races.
