Six Flags Great Adventure's Kingda Ka roller coaster is not currently in operation. We are working diligently to bring the ride back in operation as soon as possible. However, we do expect it will be closed for several weeks.
We realize that our guests' expectations for this record breaking coaster are especially high. We apologize for any disappointment or inconvenience this temporary closure may cause.
Please check here for updates on Kingda Ka. As soon as we have determined the specific date it will reopen, we will post details.
Thank you for your patience and understanding.
Vice President and General Manager,
Six Flags Great Adventure, Wild Safari and Hurricane Harbor
