Six Flags Magic Mountain currently lists Twisted Colossus as closed from August 17 through September 4, 2026. If your Valencia plan depends on the park’s hybrid racing coaster, treat that window as offline until the official board changes.
This is a dated attraction hold, not a parkwide shutdown. You can still build a Magic Mountain day around other thrill rides, but you should not bank on riding Twisted Colossus during Labor Day week unless Six Flags moves the return date earlier.
- What changed: Twisted Colossus appears on the park’s Scheduled Ride Closures board for August 17 through September 4, 2026.
- Where: Six Flags Magic Mountain in Valencia, California.
- Why it matters: Guests planning late August or early September visits lose one of the park’s signature hybrid coasters for that stretch.
- Related holds: The same board also lists X2 without an end date, SCREAM through September 11, and Looney Tunes Lodge through September 18.
- Still open: Exact reopen timing can shift; recheck the board and app the morning of your visit.
What the official board says
Six Flags Magic Mountain’s Scheduled Ride Closures page currently names Twisted Colossus with the window August 17 to September 4. The same page lists X2 without a published return date, SCREAM from August 17 through September 11, and Looney Tunes Lodge and Camp Duck Amuck Fun Fort from August 21 through September 18.
The board’s own language says attraction availability can change without notice. Treat September 4 as the currently published return marker, not a guaranteed minute-by-minute reopening clock.
Thrill Data’s live Twisted Colossus wait page also shows the ride as Closed, with no wait data collected for the current day. That independent wait surface matches the park board’s offline status even though it does not reprint the September 4 end date.
What this means for September trip planning
If you already hold tickets for August 23 through September 3, remove Twisted Colossus from any must-ride list and rebuild around machines that remain open on the day you visit. Labor Day weekend falls inside the published window, so do not assume the coaster will be back for the holiday crowd.
If Twisted Colossus is your primary reason for the trip, shift the visit to September 5 or later and reconfirm the board before you leave home. A one-day move past the published end date is cheaper friction than arriving to a still-closed signature ride.
Use Deep Arrival’s Six Flags Magic Mountain planning guide and the height-requirements list to rebuild a ride order that still hits your height and thrill targets without the hybrid coaster.
Twisted Colossus is the park’s Rocky Mountain Construction hybrid conversion of the former Colossus structure, with a 48-inch height requirement and a long racing layout that many guests treat as a top-three Magic Mountain priority. Losing it for more than two weeks changes how you sequence the rest of Screampunk District and the higher-thrill circuit, especially if you also hoped to duel with a second train.
Practical substitutes for a similar thrills-first guest usually start with Tatsu, Goliath, Full Throttle, and WONDER WOMAN Flight of Courage when those rides are open. Confirm each one on the same board and in the app, because Magic Mountain often stacks multiple holds and a substitute can also be offline on your exact date.
How this differs from other Magic Mountain holds
Twisted Colossus is a dated coaster refurbishment window. It is not the same decision as the open-ended X2 hold covered in our X2 closure update, and it is not the kids-area decision covered in our Looney Tunes Lodge closure note.
SCREAM’s August 17 through September 11 window overlaps, so a guest chasing both floorless and hybrid rides faces a longer dual gap. A guest who only needed Twisted Colossus can plan around September 4; a guest who needed both should wait until after September 11 or accept substitutes.
Confirmed: the park published the Twisted Colossus dates on its official closures board, and an independent wait tracker currently shows the ride closed. Still unknown: whether crews will finish early, slip past September 4, or stage a soft return with limited trains before a full schedule.
What to do before you buy or go
Recheck the Scheduled Ride Closures page and the Six Flags app the night before and again after arrival. Screenshots go stale quickly when parks extend or compress refurb windows.
If you are comparing Fast Lane value, do not price the add-on as if Twisted Colossus is available during this window. Spend the add-on budget on open headliners such as Tatsu, Goliath, or WONDER WOMAN Flight of Courage when those rides are operating.
Families mixing thrill seekers and younger kids should separate the decisions. The Looney Tunes Lodge hold is a play-space problem. The Twisted Colossus hold is a coaster problem. Fix each itinerary on its own terms instead of treating every Magic Mountain closure as one story.
| If you… | Do this |
|---|---|
| Need Twisted Colossus on your trip | Move the visit to September 5 or later and recheck the official board before you leave. |
| Already hold late-August tickets | Rebuild the must-ride list without Twisted Colossus and keep X2 off the plan until it posts a return date. |
| Want both Twisted Colossus and SCREAM | Wait until after September 11 or accept that both dated windows currently overlap. |
| Are planning with kids who need Lodge play spaces | Treat the Looney Tunes Lodge hold as a separate family decision from this coaster window. |
Watch for an earlier reopen, a slip past September 4, or any app alert that Twisted Colossus is back with limited operations. Those updates change whether a Labor Day or first-week-of-September ticket still fits a hybrid-coaster goal.
The practical takeaway is narrow and useful: Twisted Colossus is offline through the currently published September 4 marker, neighboring holds remain separate decisions, and the fix is either a date shift or a rebuilt ride list.
Valencia day-trippers coming up the I-5 should still confirm park hours and parking plans, but the coaster gap itself is the material change for thrill-first guests. Keep the official closures board and the Magic Mountain height chart open while you rewrite the itinerary so you do not discover the miss at the station entrance.
If Six Flags shortens the window, you can always add Twisted Colossus back. Until the board changes, plan as if the hybrid coaster will not be part of an August 17 through September 4 visit.
Passholders who visit repeatedly have more flexibility: skip the closed stretch and return after September 4 without rewriting a whole vacation. Single-day ticket buyers should decide now whether the remaining open headliners still justify the ticket price, or whether a later date is the cleaner call.
Also leave a little slack in the day for mid-visit board changes. Parks sometimes reopen a ride mid-afternoon after testing, and they sometimes extend a hold overnight. A short recheck after lunch can recover a ride you wrote off at rope drop, or confirm that the station is still dark.
When does Twisted Colossus reopen at Magic Mountain?
The park’s Scheduled Ride Closures board currently lists Twisted Colossus closed August 17 through September 4, 2026. Recheck that board before travel because dates can move.
Is the whole park closed?
No. This is a single-attraction window. Other rides continue on their own schedules, subject to the same board and day-of operations.
Is this the same as the X2 closure?
No. X2 is listed without a published end date and has separate reporting around an ongoing safety review. Twisted Colossus has a dated August 17 to September 4 window.
What should guests do for Labor Day weekend?
Assume Twisted Colossus remains offline through September 4 and rebuild the ride list around open headliners, or shift the visit to September 5 or later after confirming the board.
