If you’re looking for an adrenaline-filled summer adventure without boarding a plane, one of the most thrilling water attractions in the world is surprisingly close to Philly. Located inside the massive American Dream complex in East Rutherford, New Jersey, DreamWorks Water Park is home to the world’s tallest indoor trapdoor water slide.
Known as Thrillagascar and Jungle Jammer, the twin slides tower 14 stories above the park and begin with a heart-racing countdown before the floor suddenly disappears beneath your feet.
Riders plunge more than 140 feet at near free-fall speeds, making it one of the most intense water slide experiences in the entire North America.
What makes the trapdoor slides so terrifying? 😱

Indeed, this attraction is not for the faint of heart. Unlike traditional water slides, Thrillagascar and Jungle Jammer start inside enclosed capsules. Once the countdown begins, riders stand waiting as a trapdoor opens beneath them without warning.
The combination of the sudden drop and steep descent has made the attraction one of the most talked-about experiences at DreamWorks. Even thrill-seekers who regularly tackle roller coasters say the anticipation before the trapdoor opens is often the most nerve-racking part.
However, what may start out as terrifying ends up being unforgettable.
More than just extreme slides 🛝

No doubt, the trapdoor slides may steal the spotlight. However, DreamWorks Water Park is packed with attractions for every age and thrill level.
Visitors can enjoy:
- 🌊 Far Far A Bay Wave Pool – One of the world’s largest indoor wave pools
- 🛟 Bubbly Lazy River– A relaxing float through the parks’ tropical surroundings.
- 🏰 Madagascar Rain Fortress– A multi-level play structure complete with water cannons, slides, and giant tipping buckets.

- 🎢 More than 40 attractions – From high-speed thrills to kid-friendly adventures, there’s something for everyone under one roof.
