Six Flags Great Adventure in Jackson, NJ is scheduled to open for the 2026 season on Saturday, March 28, 2026.

Quick Scoop: When does Six Flags open in NJ?

For 2026, Six Flags Great Adventure (the main Six Flags park in New Jersey) kicks off its season on:

  • Opening Day: Saturday, March 28, 2026.
  • Location: Jackson, New Jersey (the big coaster park most people mean when they say “Six Flags NJ”).

Recent coverage notes that this March 28 date marks the start of another season of rides, shows, and seasonal events at the park.

What about the safari and water park?

  • Wild Safari (Drive-Thru Safari): Opens for the season along with the main park around the March 28 date, offering guided safari-style animal experiences.
  • Hurricane Harbor (water park): Planned to open in late May 2026 , adding water slides and pools once the weather is warmer.

Think of it as: coasters first in late March, then the full summer water-park experience by the end of May.

How this compares to past years

While dates shift slightly year to year, Six Flags Great Adventure usually:

  • Opens in late March or early April after a winter break.
  • Starts with limited days (weekends) , then expands to daily operation closer to late spring and summer.

For example, a prior season opened on March 29 with weekend-only operation at first, then more days added around spring break and summer.

Planning tips and “latest news” angle

If you’re planning a trip around opening:

  1. Target late March: Aim for March 28, 2026, or that opening weekend if you want the earliest possible visit.
  1. Expect cooler weather: Early-season days can be chilly in NJ, so layering up is smart even though the park is open.
  2. Water rides & Hurricane Harbor: Don’t count on the water park until late May 2026.

Online coverage frames the 2026 opening as the unofficial “start of warm- weather fun” in New Jersey, with emphasis on the safari, family areas, and the big ride lineup returning for another season.
