Canyon Blaster is an indoor roller coaster at the Adventuredome theme park in Las Vegas, Nevada, US. It features back-to-back vertical loops and corkscrews, and ends with a helix inside the mountain that takes up a large portion of the park. It is proclaimed as the world's largest indoor double-loop, double-corkscrew coaster. It is the second Arrow coaster to be built for an indoor amusement park. The first was Chicago Loop at the ill-fated Old Chicago in Bolingbrook, Illinois, which is now at Canobie Lake Park as Canobie Corkscrew.
