None of those tallies include the eight roller coasters coming in 2025 to the new $1 billion Six Flags Qiddiya City in Saudi Arabia — including Falcon’s Flight, which will become the fastest (155 mph) and tallest (640 feet) coaster in the world.

Six Flags Magic Mountain will add to its expansive roller coaster line-up with the debut of a new “first of its kind” coaster in 2026. Magic Mountain currently has 20 roller coasters, more than any other theme park worldwide.

Six Flags is investing $1 billion for park improvements over the next two years. A new roller coaster is to replace two rides in the Arlington park.

Six Flags Great Adventure announced some major changes to its attraction lineup on Thursday. The amusement park will be closing Kingda Ka and Green Lantern coasters to make room for a new "multi-world-record-breaking launch roller coaster" that will debut at Six Flags in 2026. No additional details were released about the new ride.

The plan is to spend half a billion dollars in 2025 and 2026 to add new rides, themed areas, food options and upgrade their technology. Arlington’s Six Flags Over Texas is one of seven parks getting a new roller coaster, in this case, the kind with one or more near vertical drops.

La Vibora, the longtime bobsled-style coaster, opened in 1986. El Diablo, a giga loop coaster, was in operation since 2019.
