6. Incredible Hulk Coaster

TPT100 Ranking: No. 9 (full ride details)

This coaster that transforms you into Dr. Bruce Banner's experiment was one of the premier attractions when Islands of Adventure opened in Florida in 1999, and now it's getting a makeover. The coaster is expected to reopen in summer 2016 after undergoing a major enhancement and refurbishment. The ride promises to be smoother as it accelerates from zero to 40 miles per hour in only two seconds and you go into a weightless "zero g" roll. You hear a roar as you gain speed, smash through the sky and plummet back to Earth.

5. Apollo's Chariot

TPT100 Ranking: No. 8 (full ride details)

This steel coaster at Busch Gardens Williamsburg in Virginia is a favorite because of its smooth, fast ride. Daring riders go through eight air-time hills (totaling 26 seconds of airtime) and plenty of oversized turns, and the ride even has a funny story about its 1999 opening. The famous Italian model Fabio was on hand to promote it, and on its first run, a 10-pound goose struck him in the face. Fabio's nose was covered in blood and he was treated for minor cuts at a hospital. Luckily, there haven't been any more reports of Italian model/bird accidents on this ride.

4. Revenge of the Mummy: The Ride

TPT100 Ranking: No. 7 (full ride details)

This "psychological thrill ride" has immersive theming, lots of surprises and a breathless journey to escape a "curse." At one point, you even feel as if you're being overrun by scarab beetles. This indoor coaster is one of the most technologically advanced rides on the list and it can be found at Universal Studios Florida, Universal Studios Hollywood and Universal Studios Singapore. Each ride has its own unique plot and track layout.

3. Nemesis

TPT100 Ranking: No. 5 (full ride details)

The builders of Europe's first-ever inverted roller coaster had a unique challenge imposed on them: The coaster could only be constructed as high as the trees that surrounded it. So what did they do? They built a lot of it in a huge hole in the ground. The coaster sends riders up just below the tree line, then plunges them into the valley at a top speed of 50 miles per hour and puts them through barrel rolls and other twists. And interestingly, the ride at Alton Towers in England carries another claim to fame — it earned a Guiness World Record in 2004 for the "Most Naked People on a Rollercoaster" at 32 (the number of seats on a single train). It kept the record until 2010, when it was broken by Adventure Island's Green Scream Rollercoaster. That ride in Scotland carried 40 naked riders.

2. The Amazing Adventures of Spider-Man

TPT100 Ranking: No. 4 (full ride details)

It took three years to produce this motion-based 3D dark ride, and the effects are stunning. You follow the webslinger across 12 screens as he crashes through streets, climbs skyscrapers and plummets 400 feet in a freefall. You'll also catch glimpses of Spidey villains such as Doctor Octopus, Hydro-Man, Scream, Electro and the Hobgoblin. And while you're aboard your Daily Bugle vehicle, you can look for a hidden message on the manhole cover that you plunge toward at the end of the ride. The Amazing Adventures of Spider-Man is at Islands of Adventure in Florida as well as Universal Studios Japan.

1. Harry Potter and the Forbidden Journey

TPT100 Ranking: No. 2 (full ride details)

This Islands of Adventure standout is an amazing thrill ride and dark ride in one, so it's no wonder that it's your No. 1 attraction on our list. It offers an in-depth look at Harry Potter's entire environment. After Hermione Granger dusts you with Floo Powder and makes you say "Observatory," you begin the journey around Hogwarts Castle, through a horde of Dementors and through a Quidditch match, among other scenes. And while you're never turned upside down, you will drop, twist, turn and sometimes lie flat on your back. The ride has been called the most advanced and engaging in the history of theme parks, and it truly makes you feel like you've entered a magical world.
