News & Rumors

Six Flags Theme Parks




Park News - (10/13/21) Good news from Six Flags Discovery Kingdom, I’m told that Kong has reopened to guests once again, which should be extra good news for the Fright Fest crowds.


icon_STOP2022 - Sidewinder Safari - (5/28/22) Congratulations to Six Flags Discovery Kingdom who will have a grand opening for their long delayed Sidewinder Safari spinning roller coaster today, following passholder previews that took place yesterday. You can see the coaster in action in the video below from the park, featuring both Reverse POV and a POV run at the end. (note: the Reverse POV has no audio track, the POV does).

    (5/6/22) Six Flags Discovery Kingdom has confirmed that their new Sidewinder Safari roller coaster will open to guests on Saturday, May 28th. The new spinning coaster has been anticipated since it was first announced for the 2020 season, but put on hold due to COVID.
    (3/21/22) A picture posted to Twitter shows off the new Sidewinder Safari spinning mouse coaster being assembled at Six Flags Discovery Kingdom this week.




    (11/17/21) A reader stopped by Six Flags Discovery Kingdom this week and sent back a couple of pictures of the track pieces and other parts on site for the new Sidewarder Safari coaster. They also sent in a few ride updates, confirming that Kong was open, The Flash Vertical Velocity was closed, and during their visit Joker broke down but had begun testing later in the day.

    (8/30/21) Six Flags Discovery Kingdom has confirmed that the long delayed Sidewinder Safari coaster is now back on track and slated to open in 2022.

    (6/7/21) Pieces for the new coaster have arrived on site and were spotted sitting in the parking lot. New signs in the park promote the coaster as coming in 2022.
    (2/27/21) In a press release from the Six Flags corporate office that covers what every park is doing for 2021, there was no mention at all of the previously announced Sidewinder Safari coaster. So either it is delayed even further, or there is always the possibility that it could have been canceled outright.
    (7/5/20) NorCal Thrills has posted an excellent trip report showing off what The Marine World Experience is really like at Six Flags Discovery Kingdom. Meanwhile they also took a look at the future site of the Sidewinder Safari coaster, noting that the park is still full of posters claiming the new coaster is still coming in 2020. While there was no active construction to be seen, other than the previous site clearing, perhaps they are hoping to have it ready by the end of 2020 as an extra attraction for the park’s winter activities.
    (4/10/20) As Six Flags is now looking to cut 2020 capital budget to save money, one rumored victim is thought to be the Sidewinder Safari spinning coaster. The previous webpage for the project is now missing from the site, and two weeks prior to the chainwide closure, the park had posted a time-lapse video from the construction site, revealing that the only thing that really has taken place so far was clearing and ground work, so this would be an easy project to put on hold.  Can anyone confirm this?
    (2/29/20) Six Flags Discovery Kingdom has posted a time-lapse time-lapse construction video of the site clearing taking place for Sidewinder Safari. Based on the video the structure in the background that has the roof taken off as the video progresses is the former load/unload structure for the park’s former Elephant Rides attraction that was closed way back in 2016, so it looks like the new coaster will be located here.

    (8/29/19) Six Flags Discovery Kingdom will mix a new animal encounter with a family roller coaster adventure in 2020 when they add Sidewinder Safari, a new spinning mouse style coaster ride. But before you ride, you’ll encounter live snakes and other reptiles as you pass through the queue. Sidewinder Safari will be the park’s 12th roller coaster.
