Six Flags St. Louis has a new name: Mid America Adventure. The rebrand is already visible on the park’s official website, and a new 2027 pass lineup changes which parks and Halloween visits are included.
This is more than a sign swap for regular visitors. The practical question is whether to buy the lower-priced Hero Pass for Missouri access or the Legend Pass for all eight Enchanted Parks, especially if Fright Fest is part of the plan.
- New name: Six Flags St. Louis is now branded Mid America Adventure by Enchanted Parks.
- Hero Pass: Starts at $75.99 before taxes and includes Mid America Adventure, Worlds of Fun, parking, discounts and one 2027 Fright Fest ticket.
- Legend Pass: Starts at $130.99 before taxes and includes all eight Enchanted Parks, parking and unlimited 2027 Halloween event access at participating parks.
- Immediate use: The official offer says a 2027 pass can be used for the rest of the 2026 season.
- Do not assume: An older Six Flags pass is not automatically the same product as a new Enchanted Parks pass.
What changed at the St. Louis theme park
The Eureka, Missouri, park now identifies itself as Mid America Adventure. The name reconnects the property with its original Six Flags Over Mid-America identity, but the operator is using a distinct Enchanted Parks brand rather than reviving the old name word for word.
Theme Park Tribune reported that the formal name is Mid America Adventure and that the change follows the park’s sale and separation from the Six Flags chain. Amusement Today also confirmed the rebrand and the launch of the 2027 pass products.
The image on this article was photographed in 2025, before the rebrand, and intentionally shows the departing Six Flags St. Louis entrance identity. Travelers should expect signs, digital listings and third-party maps to update at different speeds during the transition.
The announcement does not by itself reveal a new coaster, a park expansion or a new operating calendar. It changes the identity and pass structure first, so guests should separate confirmed admission details from speculation about future attractions.
The 2027 Hero Pass is the Missouri-focused option
Mid America Adventure’s official sales page lists the 2027 Enchanted Hero Pass from $75.99, shown as a $75 base price plus a $0.99 fee, before applicable taxes and other terms.
The St. Louis version includes admission to Mid America Adventure and Worlds of Fun. That two-park access is important: the lower tier is not strictly a one-park pass for Missouri buyers, but it also is not an all-chain product.
General parking and 10 percent discounts on eligible food and retail purchases are listed. The pass also includes one 2027 Fright Fest ticket and unlimited applicable 2026 Fright Fest access, wording that makes Halloween frequency the sharpest difference between the two tiers.
A household expecting ordinary daytime visits in St. Louis, plus perhaps one trip to Worlds of Fun, may find the Hero Pass sufficient. A guest planning repeated 2027 Fright Fest nights should calculate the cost of additional Halloween admission before choosing it.
The Legend Pass is for chain access and repeat Halloween visits
The 2027 Enchanted Legend Pass starts at $130.99, displayed as a $130 base price plus a $0.99 fee before taxes. It includes admission to all eight Enchanted Parks rather than only the passholder’s home-state options.
The official benefits list includes free general parking, 15 percent food and retail discounts, guest tickets and single-use Fast Lane benefits. Exact perk rules can vary, so the benefit page at checkout should control the purchase rather than a screenshot or social post.
The Legend Pass includes unlimited 2027 Halloween event access at participating parks, based on the individual park calendar and offerings. That does not promise every Halloween night at every property, but it is clearly broader than the single 2027 Fright Fest ticket listed for the Hero Pass.
Travelers considering an Enchanted Parks road trip should compare the price difference with daily admission, parking and the real number of parks they will visit. Buying chain access only makes sense if the itinerary uses it.
Can current passholders use the new park?
The park’s guest FAQ warns that Six Flags season passes or memberships purchased after April 6, 2026, are not valid at Mid America Adventure. That is the kind of ownership-transition rule that can surprise someone who sees a familiar park but holds a different company’s product.
Guests with an older pass should check the exact purchase date, product name and written terms instead of assuming that all Six Flags credentials carry over. Bring the confirmation email or app record if Guest Services needs to identify the product.
The 2027 pass FAQ says newly purchased 2027 Enchanted Parks passes can be used immediately for the rest of the 2026 season. It also says renewal customers may have a separate offer and will need the email address tied to the existing pass.
That creates two different questions: whether an existing Six Flags product remains valid, and whether buying a new Enchanted product unlocks the rest of 2026. Treat those as separate decisions at checkout.
What the rebrand means for a 2026 visit
A guest arriving this season should still verify the operating calendar, attraction status and event rules just as before. The new name does not guarantee that every road sign, hotel listing or navigation app has changed.
Search both names if directions or rideshare results look incomplete. The physical address remains 4900 Six Flags Road in Eureka on the official site, even though the destination name is changing.
For layout planning, Deep Arrival’s Six Flags St. Louis park map page remains a useful orientation aid while the on-site identity transitions. Verify the current official map on visit day because names and branded areas can change faster than archival guides.
If Fright Fest is the purpose of the trip, use the park’s live ticketing page to confirm whether the desired date requires separate event admission. The 2027 pass language offers a preview of next year’s structure, not a substitute for the rules governing a specific 2026 night.
How to choose between the two passes
Start with the number of realistic visits, not the size of the discount banner. Count St. Louis daytime visits, Worlds of Fun trips, other Enchanted Parks, parking needs and Halloween nights separately.
Next, price the full basket after taxes and fees. A pass can be a good value while still costing more than the headline amount once optional upgrades, food, premium parking and event admission enter the plan.
Families should also compare benefits by person. Parking generally needs one eligible credential per vehicle, while admission and event access are individual, so identical passes for every traveler may not produce the best value.
Finally, save the benefit page shown at purchase. If the operator later updates its public marketing, the dated confirmation and product terms are the cleanest record of what was included.
Planning a St. Louis theme park trip
The park sits southwest of central St. Louis in Eureka, so travel time depends heavily on the hotel and traffic window. A downtown stay can pair the park with city attractions, but it is not the same as staying beside the gate.
Visitors traveling by road can use Deep Arrival’s guide to RV parks and campgrounds near St. Louis to compare a regional base. Confirm late arrival, parking and seasonal closure rules directly with the property.
Do not let the name change hide the basic trip mechanics. Check the calendar, weather policy, ride restrictions, parking opening and Fright Fest entry conditions before leaving the hotel.
The new branding may also affect search results for restaurants, packages and local ticket sellers. Direct booking through the operator is the safest reference point when a third-party listing still says Six Flags St. Louis.
What to watch next
Watch for the 2027 operating calendar and any attraction announcement that is separate from the rebrand. The current announcement establishes the name and passes, not a full capital plan.
Watch how the park defines Fright Fest admission for 2027. The Hero Pass promises one ticket while the Legend Pass promises unlimited access at participating parks, but date-level reservation or capacity rules could still matter.
Watch for official map and app updates. During a brand transition, the website, mobile app, roadside signage and third-party navigation can carry different names without indicating that the park has moved.
Finally, watch the other Enchanted Parks properties. The St. Louis change is the first visible test of how the new operator will distinguish its destinations after the Six Flags separation.
| If your plan is… | Best next step |
|---|---|
| Mid America Adventure plus Worlds of Fun | Compare the Hero Pass with two parks’ daily admission and parking; it includes both Missouri home-state parks. |
| Three or more Enchanted Parks | Price the Legend Pass because it carries all-eight-park access. |
| One 2027 Fright Fest visit | The Hero Pass includes one ticket, but verify the event date and reservation terms. |
| Multiple 2027 Halloween visits | Compare the Legend tier’s unlimited participating-event access with the cost of added tickets. |
| You already hold a Six Flags pass | Check the purchase date and exact product; do not assume it transfers to the Enchanted Parks system. |
The new name is immediate, but the financial decision is the 2027 pass split. Hero is built around Mid America Adventure, Worlds of Fun and one 2027 Fright Fest ticket; Legend expands to all eight parks and repeat participating Halloween access. Verify the final checkout terms before buying because ownership-transition rules make old Six Flags products a separate question.
