I think you're referring to the jungle gym, kind of an inverted cone or space capsule shaped apparatus which was like a cage.  At the top, you were at least 8-10 feet above ground.  In the picture, the child at the top looks to be about that same height off the ground.  Jungle gyms were banned (along with the big merry-go-round wheel with the handles and the see-saw, remember those?) because of the inherent danger from misuse.  I see the same with the pictured play area.  Too bad because we had lots of fun on those things, but all it takes is one fall, a broken leg, and the lawsuits that follow.  What a litigious society we have today!
