Adventuredome is a five-acre indoor amusement park enclosed beneath a distinctive pink-tinted glass dome at Circus Circus Las Vegas on the Strip. It opened on August 23, 1993 as Grand Slam Canyon, a fully air-conditioned park built around a canyon-themed landscape, before being renamed Adventuredome on May 1, 1998.
The park’s centerpiece has always been Canyon Blaster, an Arrow Dynamics steel coaster billed as the world’s largest indoor double-loop, double-corkscrew roller coaster. In 2014, Adventuredome added a second thrill ride, the S&S Worldwide sit-down coaster El Loco, giving Las Vegas visitors two distinct indoor coasters alongside nearly twenty other family rides, an arcade, mini golf, and a climbing wall, all shielded from the desert heat.

The Ride Experience
Canyon Blaster remains the park’s signature ride: a 94-foot-tall Arrow Dynamics coaster reaching about 41 mph across 2,423 feet of track, with two loops and two corkscrews for four total inversions in a roughly 90-second run. It has operated continuously since the park’s 1993 opening, making it one of the longest-running indoor coasters in the country.
El Loco, added in February 2014, is a compact S&S Worldwide steel sit-down coaster reaching roughly 90 feet tall and 45 mph over about 1,300 feet of track, with two dive-loop inversions and a beyond-vertical first drop. It was only the second coaster of its model type built in the United States, giving Adventuredome a modern counterpart to the vintage Canyon Blaster.
A Climate-Controlled Escape
Because the entire park sits beneath a translucent dome, Adventuredome stays open and comfortable year-round regardless of the desert heat or occasional Las Vegas rain, a rarity among American theme parks. Beyond the two coasters, the park packs in nearly twenty attractions, including bumper cars, a pirate ship swinger, a Disk’O, laser tag, mini golf, and an arcade, all within a compact five-acre footprint just off the Strip’s north end.
Adventuredome passed 50 million total visitors by January 2009, reflecting decades as a fixture for Las Vegas families and tourists looking for a break from the casino floor below.
