2027 Explorer Pass
Costs the same as one day ticket. Good through Sept 6, 2027, with the rest of 2026 and this year's Fright Fest thrown in.
Or as low as $6/mo after a down payment
No. 0001 · EXPLORERFright Fest
Open Friday to Sunday in October, closed Monday to Thursday. Fright Fest runs select nights through Nov 1, 2026, and Boo Fest runs weekend afternoons. The water park is closed for the season.
Six Flags St. Louis is now Mid America Adventure. Enchanted Parks took over in April 2026, so it's no longer a Six Flags park. Six Flags passes bought before April 6, 2026 kept multi-park access for 2026 only.
The short version
A 2027 Explorer Pass costs $55.99, the same as one Good Any Day ticket, and the rest of 2026 comes free.
Driving in twice or more? The $75.99 Hero Pass adds free parking, which starts at $15.99 a day, so it beats Explorer by your second visit.
