Ultimate Abyss Review: Facing the Fear

Introduction. I'll be honest—staring down the entrance to Ultimate Abyss, I questioned my life choices. The 10-story drop looms above the Boardwalk like something out of a nightmare. But after 9 seconds of thrilling descent, I immediately got back in line for another go.

The Build-Up

The anticipation is half the experience. Climbing to Deck 16, watching others disappear into the tubes with varying degrees of screaming, and then shuffling forward in line as your turn approaches. The crew keeps things light with jokes, but everyone's a little nervous. When they hand you the mat and position you at the edge... that's when it gets real.

The Slide

You sit on the mat, cross your arms, and then—release. The first drop is the steepest and genuinely takes your breath away. The enclosed tube has windows where light flashes in, and eerie sound effects add to the atmosphere. It's over in about 9 seconds, but it feels both longer and shorter than that somehow. You exit laughing, slightly breathless, and probably wanting to go again.

Tips

Go early morning for the shortest lines. The wait is almost worse than the slide itself—just go! Keep your arms crossed and feet together. And yes, you will scream. Everyone does.

Conclusion

Ultimate Abyss delivers on its promise of thrills. It's genuinely exhilarating without being dangerous or too extreme. Our whole family (everyone over 44 inches) rode it multiple times. Rating: 4.5/5. Don't chicken out—you'll regret not trying it.
