One of the many Six Flags theme parks. Located in Jackson, New Jersey. The park features 13 roller coasters, the 2nd most for a Six Flags park (see Six Flags Magic Mountain), and the 5th most for any theme park in the world.

Some of the coasters at Great Adventure incluse Kingda Ka: the tallest (456 ft.) and fastest (128 mph) coaster in the world (as of June 2009); El Toro: a wooden roller coaster that is 181 ft. tall, 70 mph, and is the steepest wooden coaster in the world; Nitro, a steel roller coaster 230 ft. tall, 80mph, and about 3 minutes long! And most recently: Bizarro (formerly known as Medusa), a floorless coaster with many inversions (i.e. loops, zero-g rolls, etc.) that has recently been upgraded with new paint, a new name & backstory, trains with audio features, and elements during the ride such as flamethrowers, mist sprayers, etc.
"Wow, Great Adventure is the greatest place in the world!!"

"Hey, do you guys want to go to Great Adventure this Saturday? I have tickets."

most amazing amusement park in the world where locals who go every weekend have to put up with groups of whorish middle schoolers who think they are so cool. other people put down rides like kingda ka because they are jealous losers who wish the fastest coaster in the world came from their town! otherwise, its a great family friendly park! dont spell profanities, the workers will yell at you! also dont become angry with these workers as they continuously say "visual scan". it's their job.
whore 1: OMG IM LIKE 7
whore 2: shut up bitch, im 8!
normal people: this is my town you whore!
worker: great adventure is a family park!

a place where all the 13 year old jersey sluts go. they often give oral sex to people they don't know. and get fingered there. when at six flags, check the bushes for 13 year olds doing sexual acts.
guy 1: "Dude, yesterday I went to Six Flags Great Adventure and met some hoe. She brought me to a bush and got on her knees, and the rest is history."
guy 2: "Let me guess...she was like 13."
guy 1: "You know it."
