When is Six Flags Great Adventure least crowded?

The largest of all the Six Flags parks, Great Adventure boasts over 50 rides, including 13 roller coasters. If thrills aren’t your thing, there’s the neighboring Six Flags Wild Safari animal park, one of the largest drive-through safaris outside of Africa.

Six Flags Great Adventure has something for everyone, but what about the crowds? Some days are busier than others. Here are some of the best and worst times of the year to visit the park.

March – April

Opening Day – Great Adventure’s operating season finally begins in late March or early April. Big crowds and long lines are the norm for opening day and through the opening weekend.

Spring Break – The week after opening day is typically Spring Break time for most of the schools in the area. That means the park is open all week long and it’s usually packed. Your best bet for lighter crowds would be on the Sundays after Spring Break week.

May

Weekdays – Great Adventure is open on Thursday-Sunday in May and the weekdays are usually least crowded, although the crowds do tend to pick up a bit on Fridays.

Memorial Day Weekend – Memorial Day marks the start of the summer season and Six Flags gets very crowded for the three-day weekend.  The park is still open on the weekdays following Memorial Day, so try to go after the holiday if you can for less crowds and shorter wait times.

June

Summer Season – Six Flags Great Adventure is open everyday in June, as the park gets ready for the summer crowds. Weekdays are again the least crowded days, while Saturdays tend to be the busiest.

More schools start to get out for the summer in mid to late June, so the earlier in the month you go, the less crowded it will be. The summer crowds start to get a lot worse on the last week of June.

July

4th of July Weekend – The summer crowds are out in full force by July, and it’s typically very busy for the 4th of July.

There’s really not much relief from the summer crowds in all of July, including on weekdays, so be prepared.

August

Summer Season – The big summer crowds are still around in all of August.

September

Labor Day Weekend – Great Adventure is typically very crowded for the three-day weekend, as the summer season finally comes to an end.

The park is only open on weekends in September, and Sundays are the least crowded days.

October

Columbus Day Weekend – The three-day weekend attracts big crowds to the park. Be prepared for long lines.

Fright Fest – Fright Fest takes over for the Halloween season on Fridays and the weekends in October. The event is very popular, so try to get there early.

    I would just wait until you get there to see what the lines are like before buying Flash Pass or not. It usually isn’t too crowded that late in the season.

  • Tara

    Any thoughts on halloween day crowds?

  • Sam

    I’m thinking it will still be busy since it’s a Saturday. Get there early!

  • brian

    any idea what crowds are like in December for holidays in the park

  • Sam

    I don’t think it will be too bad, especially early in the month. Crowds should pick up a bit after Christmas though.

    Anyone know how Sundays in May (before Memorial Day weekend) are?

  • Sam

    It usually isn’t too bad since the big summer season crowds aren’t out yet.

    Hi. The park announces their opening weekend will be from march 23 to 27 this year. Would you think March 28th won’t be as packed considering most schools won’t be on spring break?
