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.


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.


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.


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.


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


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.


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.

  1. It would be AMAZING if I got a response in less than an hour…wishful thinking. I’m going to Six Flags today, May 31st. My question. How crowded? It’s the day AFTER Memorial Day, a Tuesday, everyone is in school and everybody is going back to work I’d assume. Hopefully I’ll get an answer before I decide to drive 2 hours up haha. Thanks!

  2. It’s usually manageable after Memorial Day. Most of the big summer season crowds shouldn’t be out yet.

  3. I’m looking at calendar and it says this saturday June 4th will be crowded. Weather forecast says slight chance of rain, do you think it will still be crowded? Also last week of August weekdays 29 to 31, why are these so empty? Does school start so soon?

  4. In addition, why is August less crowded than July?

  5. If it rains, that should help keep the big crowds away. The end of August is usually when schools go back in session, so it tends to be manageable by then.

  6. I noticed that june 9th is the last day on the calendar for a ghost town. Im going for my first time, what do you think the crowds will be like im really hoping for walk ons and oppurtunities for multiple rides on El-Toro and kingda ka

  7. Hey I see that August has less people than July why is that?

  8. Walk-on’s are possible, but the lines shouldn’t be too bad. It’s usually manageable on the first two weeks of the month.

  9. The summer season crowds usually start to die down on weekdays by the second week of August. Weekends are still busy until the end of the month, when schools start to go back in session.
