The 2025 season has officially come to a close for Kings Island and 2026 is starting off strong with a new Phantom Theater: Opening Nightmare update episode from the park. Some notes about the upcoming season are as follows:
2026 will be the second full season under the new Six Flags Entertainment Corporation, with all-park add-ons now working across every North American park in the chain.
Kings Island will open for the season on Saturday, April 18th, 2026. A Passholder Preview event may be held on 4/17, but I haven't seen anything official on that matter.
Phantom Theater: Opening Nightmare is set to debut this Spring as a revival of the classic Kings Island attraction that occupied the same building from 1992-2002.
There is hope that Monster will reopen after being down for all of 2025 while a little further north Invertigo has received a new lift chain, hopefully to also reopen in 2026.
The 1926 Grand Carousel will celebrate its 100th birthday this season. Similar carousels at Carowinds and Kings Dominion received informational plaques and an anniversary horse design for their 100th anniversary.
No plans have been released about other park projects, but we may see survey markers and site clearing for a potential 2027 or 2028 attraction. I believe we might also see some upgrades elsewhere in the park like we have in previous years with the Festival/Carousel Pavilion and other retail location renovations.
With new leadership at the helm of Six Flags and changes being made across the board, I will be very curious to see how this year turns out for Kings Island.
