Six Flags is North America's largest regional theme park operator, running dozens of properties spread across the United States, Canada, and Mexico. Whether you are a hardcore coaster enthusiast chasing record-breakers or a family looking for a solid summer day out, mapping the full network before you buy a pass saves you from overpaying for parks outside your driving range.

How Many Six Flags Parks Are There?
As of 2026, Six Flags operates roughly 27 distinct properties across North America after a series of significant ownership changes. Following the 2024 Cedar Fair merger, the combined company divested seven parks to EPR Properties in early 2026, and Six Flags America in Maryland closed permanently in November 2025. The network now focuses on flagship destination parks rather than smaller regional properties. The mix includes traditional theme parks and separately-gated Hurricane Harbor water parks. Always verify the current lineup directly on the official Six Flags website before purchasing a season pass, as the portfolio is actively changing.

Six Flags Theme Parks by State (US)
Finding the right park requires knowing which state holds the flagship destination properties versus the regional family spots.
California
California hosts two drastically different experiences. Six Flags Magic Mountain in Valencia holds the undisputed crown for thrill-seekers with a world-record 20 roller coasters. Mapping out the rides beforehand is essential to beat the massive crowds. Further north in Vallejo, Six Flags Discovery Kingdom offers a hybrid experience blending intense steel coasters with marine life encounters.
Texas
Texas is the birthplace of the entire franchise. Six Flags Over Texas in Arlington stands as the original park, featuring classic wooden structures right alongside modern steel giants. Down south in San Antonio, Six Flags Fiesta Texas uses the dramatic walls of an abandoned limestone quarry to create unique coaster drops you will not find anywhere else.
New Jersey and the East Coast
Six Flags Great Adventure in Jackson, New Jersey, is the heavyweight champion of the East Coast. It houses Kingda Ka, the tallest roller coaster in the world, and a massive drive-through wild safari spanning over 350 acres. The total property exceeds 510 acres - you literally need a vehicle to explore the animal reserve before reaching the coaster section. It draws crowds from both New York and Philadelphia, so arrive before opening and hit the major attractions first.
Six Flags New England in Agawam, Massachusetts, serves the Boston and Providence corridor with a strong coaster lineup and an attached water park.
Georgia and the Southeast
Six Flags Over Georgia sits just outside Atlanta and uses the natural hilly terrain to enhance its coaster designs. The adjacent Six Flags White Water in Marietta operates as a separate water park gate.
Illinois
Six Flags Great America near Chicago is a massive property known for its diverse coaster lineup, sitting in Gurnee just north of the city.
Oklahoma
Frontier City in Oklahoma City is a smaller regional park that rounds out the southern portfolio.
Six Flags Water Parks (Hurricane Harbor Locations)
Nearly half of the Six Flags portfolio consists of water parks operating under the Hurricane Harbor brand. Many Hurricane Harbor locations sit directly adjacent to the main theme parks, allowing combined-ticket access. Arlington, Jackson, and Valencia follow this convenient side-by-side model.
However, several standalone water parks require an entirely separate trip:
| Standalone Water Park | Location |
|---|---|
| Hurricane Harbor Phoenix | Phoenix, Arizona |
| Hurricane Harbor Splashtown | Spring (Houston area), Texas |
| Hurricane Harbor Concord | Concord, California |
| Hurricane Harbor Rockford | Cherry Valley, Illinois |
| Hurricane Harbor Oklahoma City | Oklahoma City, Oklahoma |
Always check whether your season pass includes access to these separate gates. Basic pass tiers often restrict entry to your home park only.

International Six Flags Locations
The brand operates beyond US borders with two major international hubs.
Canada
La Ronde sits on a dedicated island in Montreal, Quebec. Built originally for the 1967 World Fair, it provides spectacular views of the city skyline from the top of its coasters. Note that La Ronde's sale to EPR Properties was pending as of early 2026, so confirm current branding before visiting.
Mexico
Six Flags Mexico is located on the southern edge of Mexico City and is the most visited theme park in Latin America. The extreme elevation means coaster trains actually run slightly faster due to the thinner air. The resort also includes Six Flags Hurricane Harbor Oaxtepec, a separately located water park outside the city.
Parks Sold or Closed: What Changed in 2025-2026
The Six Flags network shrank considerably following the Cedar Fair merger. Understanding what has changed helps you avoid planning a trip to a park that no longer operates under Six Flags.
| Park | Change |
|---|---|
| Six Flags America (Maryland) | Permanently closed November 2025 |
| Six Flags St. Louis (Missouri) | Sold to EPR Properties, April 2026 |
| Six Flags Great Escape (New York) | Sold to EPR Properties, April 2026 |
| Valleyfair (Minnesota) | Sold to EPR Properties, April 2026 |
| Worlds of Fun (Missouri) | Sold to EPR Properties, April 2026 |
| Michigan's Adventure (Michigan) | Sold to EPR Properties, April 2026 |
| Schlitterbahn Galveston (Texas) | Sold to EPR Properties, April 2026 |
| La Ronde (Quebec) | Sale to EPR pending Q2 2026 |
EPR Properties intends to operate these divested parks through Enchanted Parks and may retain the Six Flags name through end of 2026. Verify current branding before booking.
Which Six Flags Park is the Biggest?
Six Flags Great Adventure in New Jersey takes the top spot for sheer physical size. When you combine the massive theme park footprint with the integrated Wild Safari, the property spans over 510 acres.
In terms of ride count, Six Flags Magic Mountain in California remains the undisputed king. It packs more extreme roller coasters into its hilly terrain than any other park in the world.
