About Six Flags Great Adventure
About Six Flags Great Adventure
Six Flags Great Adventure sits in Jackson, New Jersey, and has long been one of Six Flags' flagship coaster parks. The line-up is exceptional: El Toro (one of the world's top-rated wooden coasters), Nitro, Jersey Devil Coaster, Superman: Ultimate Flight, Batman: The Ride, Skull Mountain, and Green Lantern stand-up. Kingda Ka was the park's signature ride until its closure; a Safari Off Road Adventure drive-through exhibit also operates on the property.
NJ and NYC school holidays, Fright Fest and US summer weekends drive huge crowds. Weekdays in May, September and October are dramatically calmer. Check live queue times for El Toro and Nitro on arrival - they build up fast - and use our crowd calendar to pick a midweek visit for shorter waits across the whole coaster line-up.
