Like any good circus, Circus Circus has a big top – a big, pink top, to be specific. Visible from miles away, The Adventuredome, housed in the giant rosy dome, is an indoor theme park featuring an intense roller coaster called the Canyon Blaster and more than a few other rides sure to excite even the most discerning thrill-seekers. Families and small children can take advantage of the tamer – but just as fun – junior rides.
