We have seen the opening of two incredible indoor coasters this year. Both TRON: Lightcycle / Run at Walt Disney World and Darkoaster at Busch Gardens Williamsburg opened earlier in 2023 as innovative and unique roller coasters.
We thought it best to look at some of the other indoor coasters that allow you to get in your thrills no matter the weather. Let’s look at five of the best indoor roller coasters.
1. Space Mountain, Magic Kingdom

However, the original Space Mountain at Magic Kingdom in Walt Disney World has our pick as the best of them. The coaster, which opened in 1975 and was manufactured by Arrow, takes riders on a journey through outer space and features several drops, turns, and space-themed projections and props all in almost complete darkness.
While the coaster only reaches speeds of 27 miles per hour, the darkness mixed with sudden drops and turns gives riders the illusion of going much faster. For a speed that rivals most kiddie coasters, this indoor classic holds its own as a premier thrill attraction at Walt Disney World.
Guests can board one of two nearly identical tracks, Alpha and Omega. They are mirror images of one another except that the Alpha track is 10 feet longer than the Omega. After turning out of the loading platform guests enter an intergalactic lighted tunnel that carries them up the first lift hill. Along the lift, guests can spot space-related décor including two astronauts standing upside down.
Once riders reach the top they are sent down through a series of sudden drops and twists. During Mickey’s Not So Scary Halloween Party, the coaster is run in complete darkness and it is an even crazier ride than usual. That darkness really makes the coaster feel that much faster and more intense. If you have the chance to ride it in this way, take it.
2. Revenge of the Mummy, Universal Studios Orlando

The coaster opened in 2004 and features several special effects, including fire, water, animatronics, and projections. The theming of this attraction is exquisite.
Even the queue that winds you through the Museum of Antiquities is completely immersive. The ride also includes multiple launches, sudden drops, and turns in the dark, a part where the train is thrust backward, and well, you might not be as safe at the end as you think.  
The Revenge of the Mummy coasters at both Universal Studios Hollywood and Orlando were manufactured by Premier Rides, and the Orlando version is longer and faster. The coaster is housed within a 62,000-square-foot building that used to be the home of Kongfrontation. They actually had to excavate part of the foundation to accommodate one of the drops. That’s right, at one point you are below the ground level.
The coaster received an extensive refurbishment in 2022 that included updates and cosmetic upgrades. While it only reaches speeds of 45 miles per hour, the theming, effects, and dark elements of the coaster make it both unique and thrilling. It is truly a must-ride if you are visiting Universal Studios Orlando.
3. TMNT Shellraiser, Nickelodeon Universe at American Dream

Not to be confused with its Mall of America counterpart, this Nickelodeon Universe is located at American Dream in New Jersey. Nickelodeon Universe features a few indoor great coasters, but TMNT Shellraiser stands above the rest. This steel coaster manufactured by Gerstlauer is the steepest roller coaster in the world with its 121.5-degree drop.
This indoor coaster at what many would consider a “kids-themed” park really brings the thrills. It includes a slow-motion heart line roll after leaving the station and a launch that sends riders from 0-62 miles per hour in 2 seconds. If the launch and 138-foot beyond-vertical drop weren’t enough, the coaster also has seven inversions.
Not only that but before riders are sent plummeting down the steepest coaster drop in the world, they are held in place for a whopping fourteen seconds to contemplate the choices that brought them to that point. The coaster and the park are open year-round, rain or shine, so if you find yourself near Nickelodeon Universe, check out the record-breaking TMNT Shellraiser.
