Current status: What ‘closing’ means right now
As of 2025, Six Flags maintains one major amusement park in California: Six Flags Magic Mountain in Valencia. No former Six Flags locations in California are operating as Six Flags parks today. Several properties have been sold or repurposed, and a few briefly closed before reopening or being acquired by other operators. This evergreen status overview clarifies which sites are confirmed closed, which are new or pending, and what the developments mean for California visitors.
Six Flags Magic Mountain: operating as usual
Location and ownership
Six Flags Magic Mountain (1 Magic Mountain Parkway, Valencia, CA) remains open and owned by Six Flags Entertainment Corporation. It is the company’s only active California theme park and continues standard seasonal operations, including Summer Nights and Halloween events.
Recent changes and expansion
Magic Mountain has added attractions in recent years, such as West Coast Racers (opened 2019) and announced further investments for future seasons. No closure is planned at this time; operations follow the traditional seasonal calendar from spring through fall.
Former Six Flags parks in California: status and transitions

Six Flags Discovery Kingdom (Vallejo, now Six Flags Discovery Kingdom)
- Status: Originally a marine park; acquired by Six Flags in 1999 and renamed Six Flags Discovery Kingdom; sold in 2011 to PARC Management and later became Six Flags Discovery Kingdom again under other ownership; currently operating as a Six Flags park with seasonal changes.
Six Flags Hurricane Harbor (Concord, now Splash City Waterpark)
- Status: Operated as a water park under Six Flags; closed as a standalone Six Flags water park and transitioned to a new concept; current status varies by season and investor.
Rumor risk and sites sometimes confused with Six Flags closures
Occasional rumors mention closures at non-Six Flags venues or properties never operated by Six Flags. In California, no announced permanent closure affects the active Magic Mountain location. Other waterpark or amusement sites may have changed operators, been rebranded, or paused seasonal operations, but these are not part of Six Flags’ current portfolio.
What to watch in upcoming seasons
- Monitor official Six Flags channels for Magic Mountain announcements; seasonal ride rotations, ticket offers, and event calendars are published each spring.
- Track destination deals and regional parks for temporary pop-ups or partnerships, which can create limited-time experiences without affecting core operations.
